Can someone tell me which equation this is
1. f(x)= 1/4x +4
2. y=1/2x +4
3. f(x)=-2/3 +4

Answer: 52.8 kilometers

Step-by-step explanation:

This week she plans to run 2²/₅ times as much as last week.

If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.

First convert the improper fraction to a proper one:

2²/₅ = 12/5

= 12/5 * 22

= 264/5

= 52.8 kilometers

Answer:

4.672 × 10⁶

Step-by-step explanation:

Answer:

y^2-1=80

y^2=81

y = positive and negative 9

y2−1=80

Step 1: Add 1 to both sides.

y2−1+1=80+1

y2=81

Step 2: Take square root.

y=±√81

y=9 or y=−9

Answer:

y=9 or y=−9

Answer:

45km

Step-by-step explanation:

Distance covered in 1min 20sec (80sec) = 1km

Distance covered in 1 min (60sec) = 1km/80sec

Distance covered in 1Hr (3600sec) = (1/80)*3600 = 45km.

Answer:

9/24

Step-by-step explanation:

This is because when we multiply 3/8 with 3 in both numerator and denominator we get,

[tex] \frac{3 \times 3}{8 \times 3} = \frac{9}{24} [/tex]

Hence, 9/24 is required answer.

Answer:

B

Step-by-step explanation:

A square pyramid is one with a square base. The correct option is B.

A square pyramid is one with a square base. It is a right square pyramid with C4v symmetry if the top is perpendicular to the centre of the square. It is an equilateral square pyramid if all edge lengths are equal.

The place at which the up-side down pyramid will intersect with the plane will be a square.

Hence, the correct option is B.

The complete question is:

If a vertical plane cuts through a square pyramid down from the vertex, which of the following best describes the shape of the cross-section?

A. Pentagon

B. Square

C. Rectangle

D. Triangle

Answer:

y=1.5x+5

Step-by-step explanation:

Answer:

Step-by-step explanation:

No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.

Correctly stated the equation should read f(x) = (x + 2)^2 + 4

As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation

x + 2 = 0

x = - 2

That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.

n has to be negative

Answer:

B or 2nd answer.

Answer:

1) 270 degrees

2)  pi/4 rad

Step-by-step explanation:

1.) For which value of theta is sine theta = negative 1?

Given

sintheta = -1

theta = arcsin(-1)

theta = -90degrees

Since sin is negative in the third and 4th quadrant

In the third quadrant, theta = 180 + 90 = 270degrees

In the fourth quadrant, theta = 360 - 90 = 270 degrees

Hence the required value of theta is 270degrees

2) Given the radius of the circle to be 1, the y axis value will also be 1 units

Opposite = 1

adjacent = 1

hyp = √1²+1²

hyp = √2

sin theta = opp/hyp

sin theta = 1/√2

theta = arccsin(1/√2)

theta = 45 degrees

Express in radians

45 degrees = pi/4 radians

Hence the required angle in the first quadrant is pi/4 rad

Answer:

3pi/2

Step-by-step explanation:

that is only one that makes sine negative. others make it 0 or positive

Given:

The equation is:

[tex]y=2x-3[/tex]

The x-values in the given table are -1, 1, 3.

To find:

The y-values for the given x-values in the table.

Solution:

We have,

[tex]y=2x-3[/tex]

At x=-1,

[tex]y=2(-1)-3[/tex]

[tex]y=-2-3[/tex]

[tex]y=-5[/tex]

At x=1,

[tex]y=2(1)-3[/tex]

[tex]y=2-3[/tex]

[tex]y=-1[/tex]

At x=3,

[tex]y=2(3)-3[/tex]

[tex]y6-3[/tex]

[tex]y=3[/tex]

Therefore the required table is:

x          y

-1        -5

1         -1

3         3

Answer:

2x^2 + 3x - 2

Step-by-step explanation:

=> area of rectangle = length*width

=> length = (2x -1)

=> width = (x + 2)

=> area = (2x - 1) (x + 2)

=> area= 2x(x + 2) - 1(x + 2)

=> area = 2x^2 + 4x - 1x - 2

=> area = 2x^2 + 3x - 2
