Answer:

Father's age = 64 years

Step-by-step explanation:

Given:

Mummy's age = Aliyah's age + 32

Father's age = Mummy's age + 8

Tota age = 144

Find:

Father's age

Computation:

Assume;

Aliyah's age = a

So,

Mummy's age = a + 32

Father's age = a + 32 + 8

Father's age = a + 40

Aliyah's age + Mummy's age + Father's age = Total age

a + a + 32 + a + 40 = 144

3a + 72 = 144

3a = 144 - 72

3a = 72

a = 24

Father's age = a + 40

Father's age = 24 + 40

Father's age = 64 years

Answer:

A  =  P  ( 1  + r / n)  ^( t * n)

where

A  =  the amt  owed

P  = amt borrowed

r  = the  interest  rate  as a decimal

n =  the  number of compoundings  per year

t  = the  number of years

A  =    10000  (  1  + .10  / 2)^(2 *1)    =   10000  ( 1.05)^2    =  $11025

Step-by-step explanation:

15 + 36 not-equals 41, so those lengths will not form a triangle.

15 squared + 36 squared = 1,521

41 squared = 1,681

Since a squared + b squared not-equals c squared, it will not be a right triangle.

15 squared + 36 squared = 297

41 squared = 82

The translation of the parent function is f ( x ) = | x + 6 | which is shifted 6 units to the left

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the transformation of the function be a translation , where

The parent function is f ( x ) = | x |

And , the translated function is f ( x ) = | x + 6 |

So , original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

And , the function is translated 6 units to the left

Hence , the translated function is f ( x ) = | x + 6 |

Answer:

  The triangle is not acute because 2² + 4² < 5²

Step-by-step explanation:

The square of the hypotenuse of a right triangle with the given short sides would be 2² +4² = 20. So, that hypotenuse would be √20, about 4.47. The long side of this triangle is longer than that, so the angle opposite is larger than 90°. The triangle with sides 2, 4, 5 is an obtuse triangle.

  The triangle is not acute because 2² + 4² < 5²

The triangle is not acute because 22 + 42 < 52.

Option C is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

To determine if a triangle is acute, we need to check whether all three angles of the triangle are acute angles (less than 90 degrees).

Pythagorean theorem,

- If the square of the length of the hypotenuse is greater than the sum of the squares of the other two sides, then the triangle is acute.

- If the square of the length of the hypotenuse is less than the sum of the squares of the other two sides, then the triangle is obtuse.

Now,

The triangle with side lengths 2 in., 5 in., and 4 in. is not a right triangle.

So we can't use the Pythagorean theorem directly.

Now,

We can check if the sum of the squares of the two shorter sides is greater than the square of the longest side.

2² + 4² = 4 + 16 = 20

5² = 25

Since 20 < 25, we know that the triangle is not acute.

Therefore,

The triangle is not acute because 22 + 42 < 52.

Answer:

y = -4x + 14

Step-by-step explanation:

using the slope intercept form of a line

y = mx + c

Given points

slope (m) =

[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{2 - 10}{3 - 1} \\ = \frac{ - 8}{2} \\ = - 4[/tex]

taking one point as for filling x and y and finding the y intercept (c)

y =mx + c

10 = (-4) × 1 + c

10 + 4 = c

14 = c

therefore the equation is

y = -4x + 14

Answer:

2y + 8x = 28

Step-by-step explanation:

Hi there

So we are going to solve this together

m = y - y1/y2- y1 =x - x1/x2 - x1

y - 10/ 2- 10 =x - 1/ 3 -1

y -10/-8 =x - 1/2

cross multiply

2(y - 10) =-8(x -1)

2y - 20= -8x + 8

Collect terms

2y +8x = 8 +20

ANSWER = 2y + 8x = 28

Answer:

45 degrees

Step-by-step explanation:

The interior of a triangle always adds up to 180. Since one of them is a right angle, which is always 90 degrees, and two lines of the triangle are as long as eachother, 180-90 is 90 degrees, and that is divided by two, which is 45.

Answer:

1(2)^x

Step-by-step explanation:

(^x means x is an exponent.)

Since the experiment begins with a single cell, the initial value, A, is 1. The population increases by a factor of 2 every hour, so the growth factor, b, is 2. Substitute the values of A and b in the general form of an exponential expression to create the expression modeling the number of bacteria in the colony after x hours.

A(b)^x=1(2)^x

          =2^x

The exponential expression to model the number of bacteria in a colony that begins with a single cell and doubles in size every hour is [tex]1 * 2^{x}[/tex].

Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor.

Answer:

  55

Step-by-step explanation:

Here's one way to count them.

12 consecutive integers will have 3 each of the integers whose value is 0, 1, 2, or 3 mod 4. To make a total that is 0 mod 4, any of these combinations of mod 4 values may be used:

  000 -- 1 combination

  013 -- 27 combinations, 3 each of mod 0, mod 1, and mod 3

  022 -- 9 combinations, 3 of mod 0, and 3 ways to choose 2 of mod 2

  112 -- 9 combinations, 3 of mod 2, and 3 ways to choose 2 of mod 1

  233 -- 9 combinations, 3 of mod 2, and 3 ways to choose 2 of mod 3

__

Consider the set of 12 consecutive integers 1 .. 12. Then here are the 9 "233" combinations. Mod 2 integers are 2, 6, 10, and mod 3 integers are 3, 7, 11.

  (2, 3, 7), (2, 3, 11), (2, 7, 11),

  (3, 6, 7), (3, 6, 11), (6, 7, 11),

  (3, 7, 10), (3, 10, 11), (7, 10, 11)

The total number of combinations that will be divisible by 4 is ...

  1 + 27 + 9 + 9 + 9 = 55 . . . . combinations with a sum divisible by 4

__

Additional comment

The number of ways that 3 can be chosen from 12 is 220, so this is 1/4 of that total. It is perhaps not surprising that the remainders from division by 4 are uniformly distributed among the possibilities.

A computer program to list the 220 subsets and the mod 4 remainders of their totals confirms this is the correct number.

There are  [tex]55[/tex]  ways of these integers be selected to give a sum.

Given that:

Now,

Address the formula for  [tex]C(n,r)[/tex],

      [tex]C(12,3)=\frac{12!}{(12-3)!3!} \\\\C(12,3)=\frac{12!}{9!3!} \\\\C(12,3)=\frac{12*11*10*9*8*7*6*5*4*3*2*1}{9*8*6*7*5*4*3*2*1*3*2*1} \\\\C(12,3)=\frac{12*11*10}{3*2*1} \\\\C(12,3)=4*5*11\\\\C(12,3)=220[/tex]

The sum [tex]mod 4[/tex]  of any given subset increases by [tex]1[/tex] when the set is “slid” to the left.

Every subset gives rise to all four values [tex]mod 4[/tex]  by sliding each of four places.

Answer:

Option A:

x^2 + (y - 2)^2 = 9

Step-by-step explanation:

We know that the equation for a circle centered in the point (a, b) and of radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

So the first thing we need to find is the center of the circle.

We can see that the center is at:

x = 0

y = 2

Then the center is at the point (0, 2)

Now we want our circle to pass through point 2, located at a distance of 2 units from the radius of the first circle.

So the distance between the center and point 2 is 2 units plus the radius of the smaller circle:

And the radius of the smaller circle is one unit.

Then, the radius of a circle centered at (0, 2) that passes through point 2 is:

R = 1 + 2 = 3

Then we have a circle centered at (0, 2) and of radius R = 3

Replacing these in the equation for a circle we get:

(x - 0)^2 + (y - 2)^2 = 3^2

x^2 + (y - 2)^2 = 9

The correct option is A

Answer:

50 degrees

Step-by-step explanation:

the sum of all angles in a four-sided shape is 360 degrees.

our four points here are :

the center of the circle

the 2 points on the circle, where the 2 tangents touch the circle

the intersection point of the tangents (where they cross each other).

at the 2 points, where radius meets tangent, we have a right angle or 90 degrees. so, they together take already 180 degrees.

the angle at the center of the circle is 130 degrees.

so, all that is left for the angle at the tangent intersection point is

360 - 180 - 130 = 50 degrees
