If s(x) = 2 – x² and t(x) = 3x, which value is equivalent to (sof)(-7)?
mylen [45]

Answer:

- 439

Step-by-step explanation:

evaluate f(- 7) and substitute the value obtained into s(x)

f(- 7) = 3(- 7) = - 21 , then

s(- 21) = 2 - (- 21)² = 2 - 441 = - 439

Some Field Experience in the use of an Accelerated Method in Estimating 28-Day Strength of Concrete" considered regressing y =28
Brums [2.3K]

Answer:

<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>

Step-by-step explanation:

The given function is

y=1800+1.3x

Where x represents the accelerated strength in psi, and y represents 28-day standard-cured strength in psi.

Part a is about finding the y-value for x=2500

y=1800+1.3(2500)=1800+3250=5,050

Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.

Part b is about the y-value for x=2501

y=1800+1.3(2501)=1800+3251.3=5,051.3

Part c is about the y-value for x=2600

y=1800+1.3(2600)=1800+3380=5,180

Part d is about the y-value for x=2400

y=1800+1.3(2400)=1800+3120=4,920

How do I solve this??
Strike441 [17]

Answer:

r = -1/2

Step-by-step explanation:

3(5 + 4r) = -18r

15 +12r = -18r by distributive property

15 = -12r - 18r

15 = -30r

r = - 1/2r
