Answer:
domain of y = sqrt (x+4) is [-4, +inf)
Step-by-step explanation:
[-4, +inf), -4 is included because sqrt(-4 + 4) is defined but is undefined at the points from (-inf, -5].
To figure out two separate dimensions for finding a Volume of 100 cubic cm, you will look at the factors of 100 that will result in an answer of 100.
You will need the area of the triangular base and the height of the pyramid.
I will use 3 as the height for both triangle because in the formula, you will multiply by 1/3. This means you will need to get an area of 100 for each triangle.
Because you will divide by 2, you need to find 2 different sets of factors that will give you 200. I chose 20 and 5 and 25 and 4.
Please see the attached work for the calculations.
Triangle #1: Triangle #2:
b = 40 cm b = 50 cm
h(of the base triangle) = 5 cm h(of the base triangle) = 4 cm
H(of the pyramid) = 3 cm H(of the pyramid) = 3 cm
Answer:
1 and 8
Step-by-step explanation:
Answer: A. 6x3 − 5x2 − 8x + 3
Step-by-step explanation: this is a multiplication (2x − 3) = A (3x2 + 2x − 1) = B, so we are going to multiply each value from A with every value of B
for example you can start 2X from A
2X . 3X2 = 6X3
2X . 2X = 4X2
2X . -1 = -2X
now with -3
-3 . 3X2 = -9X2
-3 . 2X = -6X
-3 . 1 = -3
mow we can put every value in one equation
6X3 + 4X2 + 2X - 9X2 -6 X - 3
after that, you can simplify the common values for example
4X2 - 9X2 = -5x2
- 2X - 6 X = -8x
this the last equation that we get after simplify
6x3 − 5x2 − 8x + 3
Answer: The above described question is an EXPERIMENT.
Step-by-step explanation:
- The subjects studied were ==> 40
- The factors studied, and the number of levels for each==> 2factors were studied, each having 2 levels(desserts /no desserts and exercise/no exercise).
-The number of treatment ==> 4
-The response variable ==> Improvement in sleep ability.
