Answer:
13.22
Step-by-step explanation:
The eqtn is
hypotenuse^2 = leg^2 + leg^2
20^2 = 15^2 + L^2
400 = 225 + L^2
L^2 = 400 - 225 = 175
L = √175 = 13.22
The function f is defined by f(x)= - 1/2x^2
Write down the expression for h(x).
Answer: -1/2 (x-4)^2 + 3
Step-by-step explanation:
Since the graphs both have the same stretch of -1/2x^2, you just need to see how much they were shifted up, down, left, or right. h(x) is shifted up 3 and right 4 of f(x) so h(x) = -1/2 (x-4)^2 + 3
Answer:
[tex]h(x)=-\dfrac12(x-4)^2+3[/tex]
Step-by-step explanation:
Given:
[tex]f(x)= - \dfrac12x^2[/tex]
From inspection of the graph, [tex]f(x)[/tex] has been translated 4 units to the right and 3 units up.
Therefore, [tex]h(x)=f(x-4)+3[/tex]
[tex]\implies h(x)=-\dfrac12(x-4)^2+3[/tex]

Mitchell has been given the option of either paying his $200 bill now or settling it for $204 after 1 month (30 days). If he chooses to pay after 1 month, find the simple interest rate at which he would be charged.
The simple interest rate that he would be of 24.33% a year.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
[tex]A(t) = A(0)(1 + rt)[/tex]
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.In this problem, considering than an year has 365 days, the parameters are as follows:
[tex]A(t) = 204, A(0) = 200, t = \frac{30}{365}[/tex]
Hence:
[tex]A(t) = A(0)(1 + rt)[/tex]
[tex]204 = 200\left(1 + \frac{30}{365}r\right)[/tex]
[tex]1 + \frac{30}{365}r = \frac{204}{200}[/tex]
[tex]\frac{30}{365}r = 0.02[/tex]
[tex]r = \frac{365}{30} \times 0.02[/tex]
[tex]r = 0.2433[/tex]

Answer: LMT=95
Step-by-step explanation:
combine both problems to equal 166
x+x+72+96=166
Combine like terms
2x+168=166
Subtract 168 from 166
2x=168-166

Hugo began his science experiment with 22 grams of sugar crystals. During the experiment, the change in the mass of the sugar crystals was – 6 grams. What is the final mass of the sugar crystals?
Answer:
16
Step-by-step explanation:22 minus 6 is 16
The final mass of the sugar crystals is 16 grams if Hugo began his science experiment with 22 grams of sugar crystals.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Hugo began his science experiment with 22 grams of sugar crystals.
During the experiment, the change in the mass of the sugar crystals was – 6 grams.
Let x be the final mass of the sugar crystals.
The value of the x can be found using:
x = 22 - 6
x = 16 grams
Thus, the final mass of the sugar crystals is 16 grams if Hugo began his science experiment with 22 grams of sugar crystals.

Vertical angles measure (x-28) degrees and (0.5x-13) degrees. What is the value of x?
Answer:
x = -30
Step-by-step explanation:
Ok remember this because its important vertical angles means the two angles are congruent and congruent means when two things are the same
if those two angles are vertical angles what does that mean?
They both equal each other because they are the CONGRUENT!
x-28 = 0.5x -13
combine like terms so add 28 to both sides
x = 0.5x + 15
then subtract - 0.5x on both sides
- 0.5x = 15
then get x by itself by dividing - 0.5 on both sides
x = -30

what is the slope intercept equation of this line
Answer:
B
Step-by-step explanation:
One approach is to plug (2, -2) to every function and only B will work.
Choice A) y = 3x + 4
-2 = 3(2) + 4
-2 = 10
Does not work
Choice B) y = -3x + 4
-2 = -3(2) + 4
-2 = -2
Works
Choice C) y = -1/3x + 4
-2 = -1/3(2) + 4
-2 = -2/3 + 4
-2 = -2/3 + 12/3
-2 = 10/3
Does not work
Choice A) y = 4x - 3
-2 = 4(2) - 3
-2 = 5
Does not work
You can also just take a look at the function and see that its slope is downwards so it has to be negative. Then check the slope using rise/run.
For every 1 to the right it goes down 3, so -3/1 = -3. The only function with a slope of -3 is answer choice B.

Enter the first 4 terms of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
[tex]f(n) =3 {n}^{2} + 1[/tex]
Given:
The rule for the sequence is
[tex]f(n)=3n^2+1[/tex]
Domain of the function is the set of whole numbers greater than 0.
To find:
The first 4 terms of the sequence defined by the given rule.
Solution:
We have,
[tex]f(n)=3n^2+1[/tex]
Domain of the function is the set of whole numbers greater than 0. So, domain for first four terms are 1, 2, 3 and 4 respectively.
For n=1,
[tex]f(1)=3(1)^2+1[/tex]
[tex]f(1)=3(1)+1[/tex]
[tex]f(1)=3+1[/tex]
[tex]f(1)=4[/tex]
For n=2,
[tex]f(2)=3(2)^2+1[/tex]
[tex]f(2)=3(4)+1[/tex]
[tex]f(2)=12+1[/tex]
[tex]f(2)=13[/tex]
For n=3,
[tex]f(3)=3(3)^2+1[/tex]
[tex]f(3)=3(9)+1[/tex]
[tex]f(3)=27+1[/tex]
[tex]f(3)=28[/tex]
For n=4,
[tex]f(4)=3(4)^2+1[/tex]
[tex]f(4)=3(16)+1[/tex]
[tex]f(4)=48+1[/tex]
[tex]f(4)=49[/tex]
Therefore, the first 4 terms of the sequence defined by the given rule are 4, 13, 28 and 49 respectively.

If x = 7-p and y = 3p + 4, which of the following
expresses y in terms of x ?
step by step please !!
Answer:
Step-by-step explanation:
Answer:
y = -3x + 25
Step-by-step explanation:
You have to find p first.
You can do this by using the x equation and moving the p to the right by adding p to each side to get p + x = 7.
Now, move the x to the left by subtracting x on both sides to get a final answer of p = 7 - x
Then, you can substitute p into the y equation.
So, y = 3(7 - x) + 4.
Distribute to get y = 21 - 3x + 4
Combine like factors to get y = -3x + 25
Hope this helps! :)
