Solve for the length of the hypotenuse
Answer:
5000
Step-by-step explanation:
In a right triangle ,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
where -
c = hypotenusea & b = the other two sides of the triangleAccording to the question , let the hypotenuse of the triangle be 'c' . So ,
[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]
[tex] = > c = \sqrt{9000000 + 16000000} [/tex]
[tex] = > c = \sqrt{25000000} = 5000[/tex]
Hence , c = 5000
Answer:
5000
Step-by-step explanation:
[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000
[tex]\sqrt{25000000}[/tex] = 5000

You roll a dice twice.
Find the probability of getting 3 in first throw and 5 in second throw.
Answer:
1/6
Step-by-step explanation:
there are 6 faces on a dice so there's a 1 in 6 chance that you would roll a 3 on your second go there is still only a 1 out of 6 chance of getting a 5 because there is still 6 numbers you could roll on.

Explain the best you can because I’m struggling :)
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4

Use the Product Rule to find the derivative of :
a.[tex]y=(3x-1)^3(2x+5)[/tex]
b. [tex]y=(3x-2)(2x^2+3)[/tex]
Answer:
see explanation
Step-by-step explanation:
Using the product rule
Given
y = f(x)g(x) , then
[tex]\frac{dy}{dx}[/tex] = f(x).g'(x) + g(x).f'(x) ← product rule
(a)
let
f(x) = (3x - 1)³ , then using the chain rule
f'(x) = 3(3x - 1)² × [tex]\frac{d}{dx}[/tex](3x - 1) = 3(3x - 1)² × 3 = 9(3x - 1)²
let
g(x) = 2x + 5 ⇒ g'(x) = 2
Then
[tex]\frac{dy}{dx}[/tex] = (3x - 1)³ . 2 + (2x + 5) × 9(3x - 1)²
= 2(3x - 1)³ +9(3x - 1)²(2x + 5) ← factor out (3x - 1)²
= (3x - 1)²[ 2(3x - 1) + 9(2x + 5) ]
= (3x - 1)² [ 6x - 2 + 18x + 45 ]
= (3x - 1)²(24x + 43)
--------------------------------------------------------------
(b)
let
f(x) = 3x - 2 ⇒ f'(x) = 3
let
g(x) = 2x² + 3 ⇒ g'(x) = 4x
Then
[tex]\frac{dy}{dx}[/tex] = (3x - 2).4x + (2x² + 3). 3 ← distribute parenthesis
= 12x² - 8x + 6x² + 9
= 12x² - 8x + 9

A person invests 3000 dollars in a bank. The bank pays 4.25% interest compounded semi-annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 5600 dollars?
Answer:
The person must leave the money for approximately 14.8 years.
Step-by-step explanation:
This can be calculated using the formula for calculating the future value as follows:
FV = PV * (1 + r)^n …………………………………. (1)
Where;
FV = Future value of the investment = 5600
PV = Present value of the investment = 3000
r = semiannual interest rate = 4.25% / 2 = 0.0425 / 2 = 0.02125
n = number of semiannuals = ?
Substitute the values into equation (1) and solve for n, we have:
5600 = 3000 * (1 + 0.02125)^n
5600 / 3000 = 1.02125^n
1.02125^n = 1.86666666666667
Loglinearizing both sides, we have:
nlog1.02125 = log1.86666666666667
n = log1.86666666666667 / log1.02125
n = 0.271066772286539 / 0.0091320695404719
n = 29.6829509548973
Since n is number of semiannuals, we divide the answer by 2 obtain the number of years as follows:
Number of years = 29.6829509548973 / 2 = 14.8414754774487
Rounding to the nearest tenth of year, we have:
Number of years = 14.8
Therefore, the person must leave the money for approximately 14.8 years.

The expression x3 – 64 can be written as (x)3 – (4)3. What is the factorization of x3 – 64?
a3 – b3 = (a – b)(a2 + ab + b2)
A. (x – 4)(x2 + 4x + 8)
B. (x – 4)(x2 + 4x + 16)
C. (x – 64)(x2 + 64x + 16)
D. (x – 64)(x2 + 64x + 4,096)
Answer:
B
Step-by-step explanation:
(x - 4) because a = x and b = 4, subsitute into (a - b)
(x2 + 4x + 16) because if a = x and b = 4, you subsitute them into (a2 + ab + b2) to get your answer

Solve using a proportion and an equation. Kendra found the experimental probability of her making a penalty kick in soccer is 3/10 or 30%. Out of 40 penalty kicks, how many could she predict she will make?
Answer: The predicted number of penalty kicks = 12
Step-by-step explanation:
Given : The experimental probability of her making a penalty kick in soccer is 3/10 or 30%.
So, the proportion of penalty kicks she make = 0.3
Out of 40 penalty kicks, the predicted number of penalty kicks = 0.3 x 40
= 12
Hence, the predicted number of penalty kicks = 12

1. Mrs. McKee is thinking of buying solar panels to put on the roof of her new house. The Sunny Solar Company told her that for every 2 panels, she will save $80 on her electric bill.
Make a visual representation ( examples include: a graph, a table, or a picture) for the ratio of the panels to the money that she will save on her electric bill.
(a) Write the ratio of panels to money saved as a reduced fraction. Show your work
I need help ;-;
Answer:
The reduced fraction of the ratio of panels to money saved is 1 panel/ $30 saved on electric bill.
This is because the given parameter from the Solar Company, on the cost savings from the use of solar panels is the amount Mrs. Jolley saves on her electricity bill for every 2 solar panels = $60 \
