Which of the following is equivalent to the expression below? 9^10*9^x

Answer:

5

Step-by-step explanation:

Slope can be referred to as rise over run, where rise represents the change y-values and run represents the change in x-values of any two points the line passes through.

Since the line passes through the points (0, 0) and (1, 5), the change in y-values is 5 and the change in x-values is 1, hence the slope is 5/1=5 (ans).

Slope formula:

[tex]m=\frac{\Delta y}{\Delta y},\\m=\frac{5-0}{1-0}=\frac{5}{1}=\boxed{5}[/tex]

its 5 bc its a positive slope (It's going up) by 5 over 1 (5/1) and... 5/1 is just 5

Answer:

11.9

Step-by-step explanation:

in maths, we are aware that in triangles we can use sine, cosine, and tangent.

using tangent, we have

tan 29⁰=6.6/x

and tan 29⁰=0.5543

0.5543=6.6/x

cross multiply

0.5543x=6.6

x= 6.6/0.5543

x= 11.9

The answer is (-1,-3)

All you have to do is divide your point by 4, since it is a fraction. if its not then multiply.

Answer:

Standard error of the mean: 1.91

Step-by-step explanation:

The standard error of a sample mean is [tex]SEM=\frac{\sigma}{\sqrt{n}}[/tex] where [tex]\sigma[/tex] is the sample standard deviation and [tex]n[/tex] is the sample size. Therefore, the standard error of the mean for a sample size of 175 is [tex]SEM=\frac{\sigma}{\sqrt{n}}=\frac{25.29}{\sqrt{175}}=1.911744304\approx1.91[/tex]

Answer:

(- 6, 8 )

Step-by-step explanation:

Given the 2 equations

y = - [tex]\frac{1}{3}[/tex] x + 6 → (1)

x = - 6 → (2)

Substitute x = - 6 into (1) and evaluate for y

y = - [tex]\frac{1}{3}[/tex] × - 6 + 6 = 2 + 6 = 8

solution is (- 6, 8 )

Answer:

No, because the longest side is too short to be the hypotenuse of a right triangle.

Step-by-step explanation:

To see if the sides form a right triangle

6² + 8² = 9²

36 + 64 = 81

100 ≠ 81

The the 3rd side is too short

Answer:

The F-value is approximately 4.57

Step-by-step explanation:

The given parameters are;

The number of oceanfront homes in the sample, n₁ = 21 homes

The standard deviation of the selling prices, s₁ = $45,600

The number homes in the sample of homes one to three blocks from the ocean, n₂ = 18 homes

The standard deviation, s₂ = $21,330

The level of significance, α = 0.01

The F-test is given as follows;

[tex]F = \dfrac{s_1^2}{s_2^2}[/tex]

Therefore, we get;

F = 45,600²/21,330² ≈ 4.57

The F-value ≈ 4.57

The critical value from the F-table = 1.86236.

In this exercise we have to use the knowledge about force to calculate the critical force, in this way we find that:

[tex]F-value: 4.57[/tex]

We know that the information given by the text is:

The F-test is given as follows:

[tex]F=(S_1^2)/(S^2_2)[/tex]

So we have:

[tex]F=(45.600^2)/(21.330^2)=4.57\\[/tex]

Step-by-step explanation:

Answer: Total price to pay with 4 snacks = $48

Total price to pay with x snacks =36+3x

Step-by-step explanation:

Given: Jayden is going to see a movie and is taking his 3 kids.

Each ticket cost = $12

Cost of all tickets = 3 x $12

= $36

Price for each snack = $3

Price for 4 snacks = $3 x 4

= $12

Total price to pay = Cost of all tickets + price of all snacks

Total price to pay with 4 snacks = $(36+12)

= $ 48

Price for x snacks =  $3x

Total price to pay with x snacks =36+3x

Answer:

He has $1.87 change left after purchasing 7 packs of chalk.

Step-by-step explanation:

20/2.59 = 7.722 approx.

So Bruce can purchase 7 packs of chalk at $2.59 each.

Change left

= 20 -7*2.59

= $1.87

Answer:

A. 41

B. 1,590

C. .1

Step-by-step explanation:

A.

the equation is l*w=A

9.2*4.5=A

41.4=A

rounded it would be 41

B.

the equation is pi*r^2=A

3.14*22.5^2=A

3.14*506.25=A

1,589.6=A

^round this up to get 1,590

C.

what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)

.5*.2/2=A

.1/2=A

.05=A

.05+.05=0.1

Answer:

[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Part A:

The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].

What we're given:

Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]

Part B:

The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]

Part C:

The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].

What we're given:

Substituting given values, we get:

[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]

Answer:

[tex]{ \bf{2x - 5y = 5 - - - (a)}} \\ { \bf{x + y = 2 - - - (b)}} \\ (a) - 2(b) : \\ - 7y = 1 \\ y = - \frac{1}{7} \\ x - \frac{1}{7} = 2 \\ x = \frac{15}{7} [/tex]

Answer:

[tex]x = \frac{15}{7} , \ y = - \frac{1}{7}[/tex]

Step-by-step explanation:

2x - 5y = 5  ---------- ( 1 )

 x + y = 2  ------------ ( 2 )

x = 2 - y ---------( 3 )

Substitute x in ( 1 ) :

                         2( 2 - y) - 5y = 5

                             4 - 2y - 5y = 5

                                - 7y = 5 - 4

                                   -7 y = 1

                                       [tex]y =- \frac{1}{7}[/tex]

Substitute y in ( 2 ) :

                         [tex]x + y = 2\\\\x -\frac{1}{7} = 2\\\\x = 2 + \frac{1}{7}\\\\x = \frac{14 + 1}{7}\\\\x = \frac{15}{7}[/tex]

Answer:

50

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50
