Answer:

The estimated product is  4\times 979\approx 3920            

Step-by-step explanation:

Given : Product of 4 times 979.

To find : Estimate the product ?

Solution :

Estimating means rounding the number for easy calculation.

Estimate of 4 is 4.

Estimate of 979 is 980 as they are very near.

So, 4\times 979=4\times 980

4\times 980=3920

Therefore, The estimated product is  4\times 979\approx 3920

The sum of the measures of the interior angles of a triangle is 180°. The sum of the measures of the interior angles of a quadr
omeli [17]

Answer: 1080 degrees

Step-by-step explanation:

Since the general formular is

(n - 2 )180 = interior angle.

Where n is the number of sides the polygon has.

Octagon has 8 sides so therefore n= 8.

(8-2 ) * 180

= 6 * 180

=1080.

The total number of the interior angles measured is 1080 degrees.

the table below shows the function of f determine the value of f(3) that will lead to an average rate of change of 19 over the i
3241004551 [841]

ANSWER

f(3) =  - 25

EXPLANATION

We want to determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5].

The average rate of change of f(x) over the interval [a,b]:

=  \frac{f(b) - f(a)}{b - a}

If the average rate of change over the interval [3, 5] is 19, then;

\frac{f(5) - f(3)}{5 - 3}  = 19

From the to table f(5)=13

\frac{13 - f(3)}{2}  = 19

13 - f(3) = 19 \times 2

13 - f(3) = 38

- f(3) = 38 - 13

- f(3) = 25

f(3) =  - 25

The function y=-5x+2 is transformed by reflecting it over the y axis. What is the equation of the new function?
vampirchik [111]

y = mx + b

When a function is reflected over the y-axis, the b (2) stays the same but the slope (m) changes to its opposite sign.

since the slope is negative in this equation, it will become positive.

so the new fuction will be

y = 5x + 2
