Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid

b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75

H = 25.01 mm

= 5229 mm³

Answer:
y = -4x + (any number)
Step-by-step explanation:
you want to use the negative reciprocal of the slope for line f
so m = -4, since you didn't say any points it has to go through then the
equation of the line is y = -4x + (any number)
Answer:
(5x + 6) (x + 7)
Step By Step Explanation:
Use the sum form to the product.

Answer:
required probability is .3446
Step-by-step explanation:
It is given that most expected time of completion = 90 days
Variance = 25
We know that

Thus the standard normal deviate is given by

Applying values we get

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446
Thus required probability is .3446
Answer:

Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

Then plug these coordinates into the Point-Slope Formula Remember, in this formula, all the negative symbols give the OPPOSITE terms of what they really, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS. It does not matter which ordered pair you choose:
![\displaystyle y - y_1 = m[x - x_1] \\ \\ y - 3 = -1\frac{1}{5}x\:OR\:y + 3 = -1\frac{1}{5}x - 5](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20-%20y_1%20%3D%20m%5Bx%20-%20x_1%5D%20%5C%5C%20%5C%5C%20y%20-%203%20%3D%20-1%5Cfrac%7B1%7D%7B5%7Dx%5C%3AOR%5C%3Ay%20%2B%203%20%3D%20-1%5Cfrac%7B1%7D%7B5%7Dx%20-%205)
