Answer:

Find the attached

Step-by-step explanation:

To graph the given function, we would need to obtain pairs of points (x, f(x)). We can let x be;

-5, -4, -3, 3, 4, 5

we simply substitute each value of x in the given function to obtain the value of the function corresponding to the given x value;

when x = -5, f(-5) =  |-5+2| - 3 = 0

when x = -4, f(-4) =  |-4+2| - 3 = -1

when x = -3, f(-3) =  |-3+2| - 3 = -2

when x = 3, f(3) =  |3+2| - 3 = 2

when x = 4, f(4) =  |4+2| - 3 = 3

when x = 5, f(5) =  |5+2| - 3 = 4

The graph of the function is as shown in the attachment below.

The sum of the two areas of two circles is the 80x square meters. Find the length of a radius of each circle of them is twice as
Alborosie

Answer:

r = 4m --- small circle

R =8m --- big circle

Step-by-step explanation:

Given

Area = 80\pi\ m^2 -- sum of areas

R = 2r

Required

The radius of the larger circle

Area is calculated as;

Area = \pi r^2

For the smaller circle, we have:

A_1 = \pi r^2

For the big, we have

A_2 = \pi R^2

The sum of both is:

Area = A_1 + A_2

Area = \pi r^2 + \pi R^2

Substitute: R = 2r

Area = \pi r^2 + \pi (2r)^2

Area = \pi r^2 + \pi *4r^2

Substitute Area = 80\pi\ m^2

80\pi = \pi r^2 + \pi *4r^2

Factorize

80\pi = \pi[ r^2 + 4r^2]

80\pi = \pi[ 5r^2]

Divide both sides by \pi

80 = 5r^2

Divide both sides by 5

16 = r^2

Take square roots of both sides

4 = r

r = 4m

The radius of the larger circle is:

R = 2r

R =2 * 4

R =8m

Express p as the subject of the formula<br>q= p² - r ÷ t​
Rudik [331]

Answer:

p = \sqrt{q +\frac{r}{t} }

Step-by-step explanation:

q=p^{2}- r÷ t   using BODMAS

q = p^{2} - (r/t)

q + r/t = p^{2}

p=\sqrt{q+\frac{r}{t} }

B(7, 2) and C(-1,-9) are the endpoints of a line segment. What is the midpoint M of that line
Oksana_A [137]

Answer:

(3,-3.5)

Step-by-step explanation:

Mid-point formula : \frac{ x_{1} +x_{2}} {2}, \frac{y_{1}+y_{2}  }{2} \\\\x=\frac{7+(-1)}{2}         ,     y=  \frac{2+(-9)}{2} \\x= \frac{6}{2}              ,     y=  \frac{-7}{2} \\x=3                             ,    y= -3.5

Midpoint M of the line segment is (3,-3.5)
