The values of the functions are:

1. y = f(-7) = 128

2. y = f(5) = 0.0313

<h3>How to Find the Value of a Function?</h3>

We can evaluate a function by substituting the given value into the equation of the function, then simplify.

Given the function, y = f(x) = (1/2) ^ x

1. Find the value of f(-7):

y = f(-7) = (1/2)^-7

y = f(-7) = 2^7

y = f(-7) = 128

2. 1. Find the value of f(5):

y = f(5) = (1/2)^5

y = f(5) = 0.0313

A worker is cutting a square from a piece of sheet metal. The specifications call for an area that is 16 cm squared with an erro
masha68 [24]

Given:

area of square, A = 16 cm^{2}

error in area, dA = 0.03 cm^{2}

Step-by-Step Explanation:

Let 'a' be the side of the square

area of square, A = a^{2}                 (1)

A = 16 =  a^{2}

Therefore, a = 4 cm

for max tolerable error in length 'da', differentiate eqn (1) w.r.t 'a':

dA = 2a da

0.03 = 2\times 4\times da

da = \frac{0.03}{8}

da = 0.0375 cm

Given: x + y = 10.<br><br> GIVEN X+Y=10<br><br> If x = -21, what is y?<br><br> -31<br> 31<br> 11
iVinArrow [24]

Answer:

y = 31

Step-by-step explanation:

We'll, if x + y = 10,

and x = -21,

then: -21 + y = 10.

To solve, add 21 on both sides to get y = 31

Hope this helps :)

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in
