The factored polynomial is given as follows:

(5x - 1)(6x² + 1)

Polynomials are factored placing the common factor in evidence, then dividing all terms by the common factor.

The polynomial is:

6x²(5x - 1) + (5x - 1).

The common factor is (5x - 1), hence:

[tex](5x - 1)\left(\frac{6x^2(5x - 1)}{5x - 1} + \frac{5x - 1}{5x - 1}\right) = (5x - 1)(6x^2 + 1)[/tex]

Hence the factored polynomial is given as follows:

The measure of angle A and C will be 94.5° and 85.5°.

(5y - 3) + (3y + 27) = 180

Collect like terms

5y + 3y - 3 + 27 = 180

8y = 180 - 27 + 3

8y = 156

y = 156/8 = 19.5

(5y - 3) = (5 × 19.5) - 3 = 94.5

(3y + 27) = (3 × 19.5) + 27 = 85.5

Answer: 19

Step-by-step explanation:

Using the sum of an arithmetic series formula,

[tex]\sum^{30}_{n=2} (an+b)=2407 \implies 29(16a+b)=2407 \implies 16a+b=83\\\\\sum^{40}_{n=1} (an+b)=4220 \implies 20(41a+2b)=4220 \implies 41a+2b=211[/tex]

Multiplying the second equation by 2 gives us [tex]32a+2b=166[/tex].

Subtracting this from the second equation, we get that [tex]9a=45 \implies a=5[/tex].

Substituting this back into the first equation, we get that [tex]b=3[/tex].

The correct statement is Triangle B is a reflection of triangle A across the x-axis. Triangle C isn't a reflection of triangle A.

Given that in a coordinate plane, triangle A is reflected across the x-axis to form triangle B. Triangle A is rotated to form triangle C.

From the given figure , it says that Triangle B is a reflection of triangle An across the x-pivot. Triangle C isn't a reflection of triangle A" in light of the fact that Triangle A is in the main quadrant and its appearance with x-axis makes the triangle-B in the fourth quadrant and the triangle C which is in second quadrant can not be a reflection and annot be a rotation of triangle-A. Triangle C is drawn by taking firstly the reflection of triangle A and then rotate on the same place and increased x+3 units in above direction.

Hence, the statement correctly describes the diagram is "Triangle B is a reflection of triangle A across the x-axis. Triangle C isn't a reflection of triangle A".

The conversion is given as 1, 760 feet per second

We need to convert 20miles per hour to feet per second

First, we should convert miles to feet

1 mile = 5280 feet

Then,

20 miles = x

Cross multiply

20 × 5280 = x

x = 105, 600

Per hour = I hour = 60 seconds

To find the conversion, we divided the conversion to feet by that of the time

= 105, 600/60

= 1, 760 feet per second

Answer:

A. the adult human

B. the adult human

Step-by-step explanation:

A. There are 60 minutes in an hour, and the human's heart beats 72 bpm (beats per minute). If you multiply 60 by 72, you get 4,320 bpm. If you multiply 60 by 35, you only get 2,100 bpm.

B. If you use the same logic that 72 is greater than 35, than you can assume that the human hear makes 1,000,000 beats in less time. However, if you want to do the math, then simply divide 1,000,000 by 72. Then, divide 1,000,000 by 35. Whichever has the smaller number is the one that can make more heart beats in a faster time.

Answer:

55

Step-by-step explanation:

61.621 rounded to the nearest whole number is 62. We know this by looking at the whole number "61" and rounding its last digit by the digit to the right of it, depending if its <5 or >5. In this case, the right ones digit is "6", being greater than 5 means we can round 61.621 to 62.

The same applies to 7.173, given that "1" is less than 5, we don't round down (because we are rounding up), instead we replace remaining digits with 0, leaving us with 7.

To find the difference means to subtract;

62-7 = 55.

Answer:

x = 60 degrees

Step-by-step explanation:

1. We know that a triangle has a total angle of 180. If we look at the image closely, triangle GEH can be found, and since we know two angles, which are 40 and 80, we can find the other angle. 180 - (40+80) = 60. Angle GEH is 60 degrees.

2. If angle GEH is 60 degrees, angle EFD will also be 60 degrees, since they have the same angle side. To prove this, we can use alternate interior angles. This means that if a line crosses two parallel lines, the inner angles made have the same size.

3. Since angle EFD is x, we can find that x is equal to 60 degrees.

The distance between the coordinate point (3, 2) and line y = ¹/₄x - 9 is; 10.25 units

We want to find the distance between the coordinate point (3, 2) and line y = ¹/₄x - 9.

Thus, we will plug in 3 for x in the line equation given to get;

y = ¹/₄(3) - 9

y = 0.75 - 9

y = -8.25

Thus, we can say that point on the line is (3, -8.25)

The difference in y-values would give us the required distance;

Required distance = -8.25 - 2

Required distance = -10.25

However distance cannot be negative and so we will take the absolute value as 10.25 units.

The equation, in point-slope from, of the line that is perpendicular to the given line and passes through the point (-4,-3) is  y + 3 = 1/4(x + 4)

The complete question is added as an attachment

The points on the line are given as:

(-1, 1) and (0, -3)

Start by calculating the slope of the line using

m = (y2 - y1)/(x2 - x1)

The slope of the perpendicular line is

m2 = -(x2 - x1)/(y2 - y1)

So, we have:

m2 = -(0 + 1)/(-3 - 1)

This gives:

m2 = 1/4

The equation of the line is then calculated as

y - y1 = m(x - x1)

This gives

y + 3 = 1/4(x + 4)
