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
Where 
represents the accelerated strength in psi, and 
represents 28-day standard-cured strength in psi.
Part a is about finding the y-value for 
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 
Part c is about the y-value for 
Part d is about the y-value for 
Answer:
MAD- 2
Step-by-step explanation:
Mean=7
Answer:
78.5°
Step-by-step explanation:
We solve for the above question, using the formula for the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = The distance between the house and the base of the ladder = 4 feet
Hypotenuse = Length of the Ladder = 20 feet
Hence,
cos θ = 4/20
θ = arc cos(4/20)
θ = 78.463040967°
Approximately = 78.5°
Therefore, the angle that the ladder makes with the ground is 78.5°
6 x 9 which is 54 is the closets to 56. :)
