Answer:The answer is 12.8
Step-by-step explanation:
8 and 10 are the side lengths so you would put that check mark thingy and then under it you put 8 squared and 10 squared and then you add it up. If you have the side length and the right length (which is the x) you would subtract because the right length is the longest.

which equation represents the line that passes through the points (3,4) and (1,-2)
Answers
Answer:
y = 3x - 5
Step-by-step explanation:
First, you find the slope by finding the change in y and dividing that by the change in x of the two points.
-2 - 4 = -6, so -6 is the change in y.
1 - 3 = -2, so -2 is the change in x.
Then, since slope is change in y divided by change in x, you have -6/-2 = 3.
So far your equation is y = 3x + b and you're trying to find b to finish the equation.
To do this, you can pick one of the points and substitute the x and y values into the equation to find what value of b makes it true. Using (1, -2) we have
y = 3x + b --> -2 = 3(1) +b
-2 = 3 + b
b = -5
That means your equation is y = 3x - 5

180 is the median of the entire data.
The upper half of the data (200, 220, 240)

How to solve this
3 = (2x + 8)/3
Answers
Answer:
x = 1/2
Step-by-step explanation:
First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.
9 = 2x + 8
Then, subtract 8 from both sides to get x by itself.
1 = 2x
Finally, divide both sides by 2 so you only have one x
1/2 = x
This means that the answer is x = 1/2.
Answer:
x=1/2 or 0.5
Step-by-step explanation:
(2x+8)/3=3
(2x+8)=3x3
(2x+8)=9
2x=9-8
2x=1
x=1/2
x=0.5

Answer:
The third: f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
[tex]f(x)=(x-\sqrt5)(x+\sqrt5)(x+7)\\\\f(x)=(x^2+x\sqrt5-x\sqrt5-(\sqrt5)^2)(x+7)\\\\f(x)=(x^2-5)(x+7)\\\\f(x)=x^3+7x^2-5x-35[/tex]
Answer:
C. f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
Given zeros of cubic function:
√5, -√5 and -7The cubic function has standard form:
f(x) = ax³ + bx² + cx + dWithout multiplying lets find the value of a, b, c and d:
a = 1 as all the answer optionsSum of the roots
-b/a = √5 - √5 - 7 = -7, so b = 7Sum of the products of the roots (taken two at a time)
c/a = √5*(-√5) + √5*(-7) + (-√5)(-7) = - 5, so c = -5Product of the roots
- d/a = √5*(-√5)*(-7) = 35, so d = -35So the cubic function is:
f(x) = x³ + 7x² - 5x - 35Correct option is C
Lea invests a sum of money in a savings account with an interest rate of 3.4% compounded continuously. After 10 years, the balance is $1900. What is the amount of her initial investment?
Answers
Answer:
$1,352
Step-by-step explanation:
The computation of the initial amount is shown below:
As we know that
Ending value = Initial investment × e^{rate, time period}
$1,900 = Initial investment × e^{3.4%, 10}
$1,900 = Initial investment × e^0.34
$1,900 = Initial investment × 1.404947591
So, the initial investment is
= $1,900 ÷ 1.404947591
= $1,352

Solve each equation.
1/3a = -5 a = ?
12 - b = 12.5 b = ?
-0.1 = -10c c = ?
Answers
Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1
