What are the answers to 9 and 10?

If you mean,

[tex]0.61^{2x + 1} = 39[/tex]

then the answer is going to be

[tex]x = \frac{log39}{2log \: 0.61} - \frac{1}{2} [/tex]

but if you mean,

[tex]0.61 ^{2} x + 1[/tex]

then, the answer is going to be, x = 102.123085.

Answer:

m<2 = 130°

Step-by-step explanation:

m<1 + m<2 = 180° (angles on a straight line/linear pair theorem)

First, we need to find m<2.

m<1 + 90° + 40° = 180° (sum of triangle)

Add like terms

m<1 + 130 = 180

Subtract 130 from each side

m<1 = 180 - 130

m<1 = 50°

Thus:

50° + m<2 = 180°

Subtract 50° from each side

m<2 = 180 - 50

m<2 = 130°

1.) 1

Let's start with 18 degrees and then subtract 12 degrees from it

18-12=6

Now let's take 6 degrees and subtract 5 from it

6-5=1

At 2 pm the temperature was 1 degree.

2.) $125

Start with the total amount John had ($250) and then subtract his remaining amount ($125) to find out how much he withdrew.

$250-$125=$125

Answer:

V = 63°

U = 29°

X = 12°

Step-by-step explanation:

given that T = 88

88 = 7x+4

88 - 4 = 7x

84 = 7x

84 = 7*12

x=12

V = 60 + 3 = 63

U = 24 + 5 = 29

88 + 63 + 29

Check : 88 + 63 + 29 .= 180

Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.

3x/5+25y=10, multiply all terms by 5 and the denominator cancels out

3x+125y=50, subtract 3x from each side

125y=-3x+50, divide both sides by 125

y=(-3+50)/125

slope=m=-3/125

y intercept=b=2/5

Answer:

Since the calculated value of z= 1.869 does not fall in the critical region we accept the null hypothesis H0: p1≠ p2  the data provides evidence that the proportion of high school students in metropolitan areas who have internet access during school hours is different than the proportion of rural high school students who have internet access during school hours.

Step-by-step explanation:

Let p1= proportion of the high school students having internet access

p2= proportion of the rural school students having internet access

1) The null and alternate hypothesis are

H0: p1≠ p2  against the claim   Ha: p1= p2

2) We choose significance level ∝ =0.05

3) The test statistic under H0 is

z= p1^- p2^/√ p^q^( 1/n1 + 1/n2)

Now

p1^= 768/850= 0.9035

p2^= 308/355= 0.8670

p^= 768+ 308/850+ 355= 1076/1205

p^= 0.8929

q^= 1-p^= 0.1070

Putting the values

z= p1^- p2^/ √p^q^( 1/n1 + 1/n2)

Z= 0.9035-0.8670/sqrt [0.8929*0.1070( 1/850 + 1/355)]

z= 0.0365/ sqrt [ 0.0955403 (0.001176 + 0.002816)]

z= 0.0365/ 0.019531

z= 1.8688

The critical region is  z∝/2 = ± 1.96

The value of z is 1.8666. The value of p is 0.06148 which is greater than 0.05

Conclusion:

Since the calculated value of z= 1.869 does not fall in the critical region we accept the null hypothesis H0: p1≠ p2  the data provides evidence that the proportion of high school students in metropolitan areas who have internet access during school hours is different than the proportion of rural high school students who have internet access during school hours.

Answer:

Nevaeh will have 1224.33 and Paisley will have 1275

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12

Your answers are C and D

Step-by-step explanation:

If you pay attention to the chart you will notice that medium duty fabric can last from 9000 to 15000 rubs meaning that since fabric B lasted 9200 it would be a medium duty fabric, making Fabric A light duty fabric.

A: This is INCORRECT because fabric B is medium duty

B: This is INCORRECT because Fabric B lasted longer than Fabric A

C: This is CORRECT because Fabric B is medium duty fabric

D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric

E: This is INCORRECT because Fabric A does not meet the requirements to be a Medium duty fabric.

Step-by-step explanation:

Use Pythagorean therom

A^2 + B^2 = C^2

Given:

The graph of a relation.

To find:

Whether the given relation in the graph is a function or not.

Solution:

First we need to understand the meaning of open circles and closed circles.

Open circle: It is a unfilled circle, it means, that value is not included in the solution set.

Close circle: It is a completely filled circle, it means, that value is included in the solution set.

A relation is a function if their exist a unique y-value (output value) for each x-value (input value).

The graph of a relation is a function, if the graph intersect each vertical line at most once. It is known as vertical line test.

For the vertical lines x=-1 and x=1, the graph has only one close circle and all other vertical line intersect the graph at most once.

Since the graph passes the vertical line test, therefore it represents a function.

Answer:

58

Step-by-step explanation:

Answer:

since the median means middle, you lay the numbers out from least to greatest.

Step-by-step explanation:

52, 72, 96, 21, 58, 40, 75 would go to

21, 40, 52, 58, 72, 75, 96.

then you cross out the numbers in a pattern so like

no more 21 and no more 96

no more 40, and no more 75

no more 52 and no more 72

this leaves you with 58!

Answer:

A) PK

Step-by-step explanation:

The side lengths of the triangle are x = 12.375 cm , y = 8.475 cm   .

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.

The basic trigonometric ratios formulas are given below,

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

sec θ = Hypotenuse/Base

cosec θ = Hypotenuse/Perpendicular

cot θ = Base/Perpendicular

According to the question

Hypotenuse of the triangle r = 15 cm

Perpendicular for ∠ θ  =  y

Base for ∠ θ  =  x

sin(θ)=0.565

cos(θ)=0.825

Now, using trigonometric ratio

sin θ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]

sin(θ)=0.565  (given)

0.565 = [tex]\frac{y}{r}[/tex]

0.565 * r = y

y = 0.565 * 15

y = 8.475 cm  

cos θ = [tex]\frac{Base}{Hypotenuse}[/tex]

cos(θ)=0.825

0.825 = [tex]\frac{x}{r}[/tex]

0.825 * r = x

x = 0.825 * 15

x = 12.375 cm

Hence, the side lengths of the triangle are x = 12.375 cm , y = 8.475 cm.
