Answer:

The missing side length is 5.7

Step-by-step explanation:

Using the pythagoream theorem you can find the missing side length of a right triangle.

The formula is [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are the lengths of the triangle legs and c is the hypotenuse.

So yours would be:

[tex]7^{2} + x^{2} = 9^{2}[/tex]

Square the numbers:

[tex]49 + b^{2} = 81[/tex]

Isolate b:

[tex]b^{2} = 32[/tex]

Square root both sides:

[tex]b=\sqrt{32}[/tex]

Simplify:

[tex]\sqrt{32} = 5.7[/tex]

Answer:

reggie made an error

the correct scale factor is 2/3

Step-by-step explanation:

we want to get from A to A', B to B', and ultimately C to C'

to get there, we must multiply each value in each point by the scale factor.

let's start out with reggie's scale factor. he multiplies each value in C by 3/2 to get to C'. we can try this out with one point, e.g. A

for A: 3/2 * (-12, -6) = (-18, -9). this is not A' = (-8, -4)! thus, 3/2 cannot be the scale factor

now, onto hillary's scale factor of 2/3

for A: 2/3 * (-12, -6) = (-8, -4). this is A'! thus, hillary is correct and reggie made an error

the correct scale factor is thus hillary's: 2/3

Answer:

shown below

Step-by-step explanation:

9 different possible tiles to choose, but there are duplicates of two types of tiles. Out of 9 tiles, two of them are S. Therefore, the probability you choose an S is 2/9 (however much percent that is).

You'd reverse the math for letters other than P:

Out of 9 tiles, two of them are P. 9 minus 2 is seven. Seven out of 9 characters are not the letter P. Therefore, the probability you choose any letter other than P is 7/9 (however much percent that is).

Answer And Step-by-step explanation:

1. b + 59 = 90

90 - 59 =b

⇒ b = 31

3. 29 + b = 90

90 - 29 = b

⇒ b = 61

5. 23 + b = 90

90 - 23 = b

⇒ b = 67

7. 32 + b = 90

90 - 32 = b

⇒ b = 58

18. 88 + b = 180

180 - 88 = 92

⇒ b = 92

20. 96 + b =180

180 - 96 = b

⇒ b = 84

22. 73 + b = 180

180 - 73 = b

⇒ b = 107

24. 91 + b = 180

180 - 91 = b

⇒ b = 89

Answer:

f(g(x)) = 5(3x + 7)

Step-by-step explanation:

Solving f(g(x))

Answer:

[tex]f(g(x)) = 3(5x + 7)[/tex]

Step-by-step explanation:

Step 1:  State the eqautions

[tex]f(x) = 5x + 11[/tex]

[tex]g(x) = 3x + 2[/tex]

Step 2:  Insert the equation and solve

[tex]f(g(x)) = 5(g(x)) + 11[/tex]

[tex]f(3x + 2) = 5(3x + 2) + 11[/tex]

[tex]f(3x + 2) = 15x + 10 + 11[/tex]

[tex]f(3x + 2) = 15x + 21[/tex]

[tex]f(g(x)) = 15x + 21[/tex]

Step 3:  Simplify completely

[tex]f(g(x)) = 15x + 21[/tex]

[tex]f(g(x)) = 3(5x + 7)[/tex]

Answer:  [tex]f(g(x)) = 3(5x + 7)[/tex]

The cylinder which would have the greater volume is that in which the two shorter sides together, you get a short, fat cylinder.

It follows from the task content that the cylinder is made from the same paper dimensions.

On this note, it follows that when the shorter sides are joined, the longer side represents the height of the cylinder formed.

Consequently, the shorter cylinder has the greater volume.

Step-by-step explanation:

just divide 105 by 5?

the full question wasn't here so I just guessed what u were trying to say

Answer:

h = 110°

Step-by-step explanation:

1) A pentagon has 5 sides that sum up to 540°. We know it is 540° because of this formula that is used to find the sum of the interior angles of any polygons. n is the number of sides.

= (n - 2) x 180

= (5 - 2) x 180

= 3 x 180

= 540°

2) We can now set up an equation.

70 + 100 + 120 + 140 + h = 540

430 + h = 540

h = 540 - 430

h = 110°

Given formula: [tex]\sf A_n= -4(2)^{n-1}[/tex]

simplify substitute the number of term by replacing n

Find first five terms:

[tex]\sf A_1= -4(2)^{1-1}[/tex]  ⇒  [tex]\sf A_1= -4[/tex]

[tex]\sf A_2= -4(2)^{2-1}[/tex]  ⇒  [tex]\sf A_2= -8[/tex]

[tex]\sf A_3= -4(2)^{3-1}[/tex]  ⇒  [tex]\sf A_3= -16[/tex]

[tex]\sf A_4= -4(2)^{4-1}[/tex]⇒  [tex]\sf A_4= -32[/tex]

[tex]\sf A_5= -4(2)^{5-1}[/tex]⇒  [tex]\sf A_5= -64[/tex]

Tenth term:

[tex]\sf A_{10}= -4(2)^{10-1}[/tex]   ⇒  [tex]\sf A_{10}= -2048[/tex]

Answer:

[tex]\sf a_1=-4\\a_2=-12\\a_3=-20\\a_4=-28\\a_5=-36\\a_{10}=-76[/tex]

Step-by-step explanation:

[tex]\textsf{Given sequence}: \sf a_n=-4(2n-1)[/tex]

This formula is for the nth term of the sequence.

Therefore, to find any term of the sequence, substitute the position of the term you wish to find as n.

For example, to find the 10th term, substitute n = 10 into the formula:

[tex]\begin{aligned}\sf a_{10} & =-4[2(10)-1)]\\ & = -4(20-1)\\ & = -4(19)\\ & = -76\end{aligned}[/tex]

To find the first 5 terms, substitute n = 1 through n = 5 into the formula:

[tex]\sf a_1=-4[2(1)-1]=-4(2-1)=-4(1)=-4[/tex]

[tex]\sf a_2=-4[2(2)-1]=-4(4-1)=-4(3)=-12[/tex]

[tex]\sf a_3=-4[2(3)-1]=-4(6-1)=-4(5)=-20[/tex]

[tex]\sf a_4=-4[2(4)-1]=-4(8-1)=-4(7)=-28[/tex]

[tex]\sf a_5=-4[2(5)-1]=-4(10-1)=-4(9)=-36[/tex]

Answer:

= [tex]\frac{x+1}{x(x-1)}[/tex] × [tex]\frac{3(x-1)}{4}[/tex] ← cancel (x - 1) on numerator / denominator

= [tex]\frac{x+1}{x}[/tex] × [tex]\frac{3}{4}[/tex]

The table is a linear regression model, and the equation of the regression model is y = 0.24x + 0.77

See attachment for the required scatter plot

From the attached scatter plot, we can see that the points are almost on a straight line

Hence, the best model that fits the scatter plot is a linear model

Using a graphing calculator, we have the following calculation summary:

The regression equation is represented as:

y = bx + a

So, we have:

y = 0.23929x + 0.77143

Approximate

y = 0.24x + 0.77

Hence, the equation of the regression model is y = 0.24x + 0.77

Answer:

Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

Answer: So therefore your answer would be 7 3/4

Step-by-step explanation: Okay so sun's you are trying to increase the recipe by four times That means you need to do what the recipe calls for four times and times what the recipe calls for by four or how many times larger you want to make it. So first we would do 3/4 X 4 = 12/16 And then from there we need to simplify And for this I'm pretty for sure lol We are going to divide the top by three and then the bottom by four.

When x = - 9, I get same value of 6.7 x 10^-18 to 1 d.p

Hope this helps!

The value of x that satisfies the given equation is -9.

The correct option is (A).

A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the making of mathematics.

As per the given data:

We are given an equation, and we have to find the value of x that satisfies the equation.

We can use the following rule of exponents to find the result of the given equation:

(i) [tex](a^m)^n = a^{m \times n}[/tex]

(ii) [tex]a^m = a^n[/tex] then m = n

For the given equation:

[tex]3^{4x} = 27^{x - 3}\\3^{4x} = 3^{3(x - 3)}\\3^{4x} = 3^{3x - 9}[/tex]

4x = 3x - 9

4x - 3x = -9

x = -9

Hence, the value of x that satisfies the given equation is -9.

Answer:

Step-by-step explanation:

The range = 2 = (greatest number in the set) - (lowest number in the set)

→ If we took x < 1 then the range would be 3 - x > 3 - 1 then 3 - x > 2 which is impossible ,therefore x could not be less than 1

→ If we took x > 3 then the range would be x - 1 > 3 - 1 then x - 1 > 2 which is impossible ,therefore x could not be higher than 3

1 ≤ x ≤ 3

then

x = 1 or x = 2 or x = 3
