Step-by-step explanation:

a²+b²=c²

a²+b²=c²√91²+√78²=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169 =13

Answer:

3,5,7,9,11,13,15,17

Step-by-step explanation:

If rabbit starts at 0 the following are the possibilities

-4-2-1=-7

-4-2+1=-5

-4+2-1=-3

-4+2+1=-1

4-2-1=1

4-2+1=3

4+2-1=5

4+2+1=7

If the rabbit starts at 10 then

10-7=3

10-5=5

10-3=7

10-1=9

10+1=11

10+3=13

10+5=15

10+7=17

Answer :

P^2 + 3^2 MIGHT be the answer because…

Step-by-step explanation:

when simplifying and expression like that you have to do something called “wording it out”so in this case you can tell that you are going to have to times 2 by whatever p+3 equals. So we add 2 to both the numbers as a exponets since it(2) is being going to be used to multiply, multiple numbers.
Hope this helps you!

Answer:

y = 3x-3

Step-by-step explanation:

i found the slope by comparing the points (1,0) and (0,-3)

the difference of the y-values over the difference of the x-values equals 3

[tex]\frac{(-3-0)}{(0-1)}[/tex] equals -3/-1 or 3

the y-intercept, as seen in graph, is -3

therefore, y = 3x-3

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that   [tex]\frac{1}{x^{n}} = x^{-n}[/tex]

In this case, [tex]\frac{1}{y^{24}} = y^{-24}[/tex]

Set that equal to [tex](y^{b})^{4}[/tex]:

[tex](y^{b})^{4} = y^{-24}[/tex]

Apply the exponent rule that [tex](x^{m})^{n} = x^{mn}[/tex] so now you get:

[tex]y^{4b} = y^{-24}[/tex]

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6

Answer:

10

Step-by-step explanation:

Here it's given that the area of the shaded region is 48 u² and we need to find out the value of x .

The given figure is made up of two rectangles where the smaller one is inscribed into the bigger one .

So that ,

[tex]\longrightarrow[/tex] ar(bigger) - ar(smaller) = 48

[tex]\longrightarrow[/tex] [ (x+3) (x-4)] - 3(x) = 48

[tex]\longrightarrow[/tex] [ x² - 4x +3x -12 - 3x ] = 48

[tex]\longrightarrow[/tex] x² -4x -12 -48 = 0

[tex]\longrightarrow[/tex] x² - 4x - 60 = 0

[tex]\longrightarrow[/tex] x² - 10x + 4x - 60 = 0

[tex]\longrightarrow[/tex] x( x -10) +4(x -10) = 0

[tex]\longrightarrow[/tex] (x +4)(x-10) = 0

[tex]\longrightarrow[/tex] x = -4,10

[tex]\longrightarrow[/tex] x = 10

Step-by-step explanation:

The surface area (x^2) that you will be provided as the base is made from the formula (3\sqrt(3)/2)s^2. s is the length of one side of the hexagon. In order to get surface area, you will also be provided the height of the prism. From there, set x^2=(3\sqrt(3)/2)s^2 and solve for s. Then multiply s * the height of the prism *8. Then, add 2x^2 to that value for total surface area/

Answer:

Step-by-step explanation:

so  for every 3 Reid washes there are 4 Elsie washes

the ratio of washing is 3:4

lets add 3 and 4 up

3 + 4 = 7

now lets divide the total number of washes by the added ratio

84/ 7

=12

now we know that 1 part is 12

to find Elsie's part we need to x 12 by how many parts she has got

she washed 4 times

4 x 12

=48

Answer:

14 million dollars

Step-by-step explanation:

We notice that there's a pattern on the graph. The company has a loss of 2 million then it gains 4 million and so on. Given this rule, we notice that in 2007 that the company gained 4 million that time and was at 16 million. So, in 2008, the company should lose 2 million, thus giving a total of 14 million dollars.

Answer:

[tex]\sqrt{11}[/tex]

Step-by-step explanation:

well first you have to plug in a and c in the Pythagorean theorem.

[tex]a^2+b^2=c^2\\(2\sqrt{2})^2+b^2 =(\sqrt{15})^2[/tex]

then squaring the square roots cancels them out sooo it becomes

[tex]4 +b^2=15[/tex]

and then isolate b

[tex]b^2 = -4 +15\\\\\\b=\sqrt{-4+15} \\b=\sqrt{11}[/tex]

and there you have it. b is [tex]\sqrt{11}[/tex]

Option D is your answer.

Step-by-step explanation:

We got

[tex] \frac{f(x + h) - f(x)}{h} [/tex]

The function here is

9x^2 so we got now

[tex] \frac{9(x + h) {}^{2} - 9 {x}^{2} }{h} [/tex]

[tex] \frac{9( {x}^{2} + 2hx + {h}^{2} - 9 {x}^{2} }{h} [/tex]

[tex] \frac{9 {x}^{2} + 18hx + 9 {h}^{2} - 9 {x}^{2} }{h} [/tex]

Cancel out terms.

[tex] \frac{18hx + 9h {}^{2} }{h} [/tex]

If we direct subsitue we get

[tex] \frac{0}{0} [/tex]

which is intermidate form in calculus so now, let try to find another way to evaluate this, we can factor out 9h

[tex] \frac{9h(2x + h}{h} [/tex]

Cancel out h

[tex]9(2x + h)[/tex]

Subsitue 0 for h.

[tex]9(2x + 0)[/tex]

[tex]9(2x)[/tex]

[tex]18x[/tex]

The answer here is 18x.

It is the original amount of money the bank loans the borrower.

Step-by-step explanation:

The person that would have more money in their account is Jada.

Total amount = starting balance + (number of weeks x amount saved per week)

$400 + ($15 x 13)

$400 + 195

= $595

Total amount = starting balance + (number of weeks x amount saved per week)

$250 + ($25 x 13)

$250 + 325

= $575
