f(x)= {x+4 if x<5
{8 if 5 < or equal to x<7
{2x-1 if 7 < or equal to x < or equal to 10
for f(x), evaluate the following:
A. f(0)
B. f(6)
show all of your work.
Answer:
A. f(0) = 4
B. f(6) = 8
Step-by-step explanation:
When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.
A.x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.
f(0) = 0 +4 = 4
__
B.x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.
f(6) = 8
What does X equal in this 30-60-90 triangle?
Answer:
19/2, or 9.5

Start at (5, 4). Move 5 units east, 4 units south, 4 units west, 4 units north, and 1 unit west.
What is the ordered pair of the final point?
Using translation concepts, it is found that the ordered pair of the final point is given by:
D. (5,4).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this situation, considering that we start at point (5,4), the translations are as follows:
5 units east, hence x = x + 5 = 10.4 units south, hence y = y - 4 = 0.4 units west, hence, x = x - 4 = 6.4 units north, hence y = y + 4 = 4.1 unit west, hence x = x - 5 = 5.It ends at the starting point, hence option D is correct.

Terry has an investment account which compounds interest continuously at an annual interest rate of 1. 4%. After 3 years, he has $1700 in the account. How much money did he initially place in the account? Round your answer to the nearest dollar. Do NOT round until you've calculated the final answer
Answer:
$1,630.08
Step-by-step explanation:
The value of an amount earning interest continuously compounded is given by the formula ...
A = Pe^(rt)
The value of P can be found by dividing by its coefficient:
P = A/(e^(rt)) = Ae^(-rt)
P = $1700·e^(-0.014·3) ≈ 1630.0786
Terry placed $1,630.08 in the account.
A swimming pool has a length of 28 feet, a width of 16 feet, and a depth of 7 feet.
How much water can the swimming pool hold?
Answer:
The pool can hold 3,136 cubic feet of water
Step-by-step explanation:
To know how much water the pool can hold, we need to find the volume of this swimming pool, because the volume is how much a container can hold.
The formula for volume is L*W*H (length times width times height)
Let's multiply!
28*16*7=3136
Wich is an equation of the line with a slope of 1/4 and a y-intercept of -2
Answer: y = 1/4x -2.

Two triangles that have three pairs of proportional sides are always similar. Identify the ratios of the length of
each side. Tell whether the triangles are similar or not similar and explain why.
Triangle 1: 18, 24, 36
Triangle 2: 16, 18, 24
Answer:
Step-by-step explanation:
Given "Two triangles that have three pairs of proportional sides are always similar."
Triangle 1: 18, 24, 36
Triangle 2: 16, 18, 24
16/18 = 8/9
18/24 = 3/4
24/36 = 2/3
So the three pairs of sides are not proportional and the triangles are not similar.
No as
One ratio is unsimilar so triangles are not similar

The equation having a sum that is a whole number is 0/5 + 1/5 + 2/5 + .... + 5/5
What is an whole number?A whole number means a number that does not include any fractions, negative numbers or decimals.
Given that, number sentences show a pattern in the sum of the fractions from 0 to 1 for different denominators,
1) 0/5 + 1/5 + 2/5 + .... + 5/5 =
1/5(0 + 1 + 2 + 3 + 4 + 5) = 1/5(15) = 3 [whole number]
2) 0/6 + 1/6 + 2/6 + .... + 6/6 =
1/6(0 + 1 + 2 + 3 + 4 + 5 + 6) = 21/6 = 7/2 [fraction]
3) 0/8 + 1/8 + 2/8 + .... + 8/8 =
1/8(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8) = 36/8 = 9/2 [fraction]
4) 0/12 + 1/12 + 2/12 + .... + 12/12 =
1/12(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) = 78/12 = 13/2 [fraction]
Hence, the equation having a sum that is a whole number is 0/5 + 1/5 + 2/5 + .... + 5/5
