Answer 2

Answer:

Step-by-step explanation:

the straight sides are just 4.5 *2 = 9 cm

the arcs are  2[tex]\pi[/tex]r * Ф/360

where Ф= 50 for this problem

and r = 8

the inner arc is  2[tex]\pi[/tex](3.5) *50/360 = 3.05432

the outer arc is 2[tex]\pi[/tex](8)*50/360 = 6.98131

total is 19.0356

to 3 sig figs is 19.036  :)

Find the value of x in The parallelogram.

Answers

Answer:

122 degrees

Step-by-step explanation:

A parallelogram has 360 degrees in total

360 - (58 + 58) = 244

244/2 = 122

I hope this helped you!

Answer:

x = 122

Step-by-step explanation:

Consecutive angles in a parallelogram are supplementary, sum to 180° , so

x + 58 = 180 ( subtract 58 from both sides )

x = 122

Answers

Answer:

(3, 6)

Step-by-step explanation:

[tex]y=4x-6[/tex]

[tex]6=4(3)-6[/tex]

[tex]6=12-6[/tex]

[tex]6=6[/tex]

[tex]3y=-2x+24[/tex]

[tex]3(6)=-2(3)+24[/tex]

[tex]18=-6+24[/tex]

[tex]18=18[/tex]

x = 3, y = 6

By substitution method,

[tex]y = 4x - 6[/tex]

[tex]3y = - 2x + 24[/tex]

[tex] \frac{3y - 24}{ - 2} = x[/tex]

[tex]y = 4( \frac{3y - 24}{ - 2} ) - 6[/tex]

[tex]y = \frac{12y}{ - 2} + \frac{ - 96}{ - 2} - 6[/tex]

[tex]y = \frac{12y}{ - 2} + 48 - 6[/tex]

[tex]y = \frac{12y}{ - 2} + 42[/tex]

[tex]y - 42 = \frac{12y}{ - 2} [/tex]

[tex] - 42 = \frac{12y}{ - 2} - y[/tex]

[tex] - 42 = \frac{12y}{ - 2} - \frac{ - 2y}{ - 2?} [/tex]

[tex] - 42 = \frac{12y + 2y}{ - 2} [/tex]

[tex] - 42 = \frac{14y}{ - 2} [/tex]

[tex] - 42 \times - 2 = 14y[/tex]

[tex]84 = 14y[/tex]

[tex] \frac{84}{14} = y[/tex]

[tex]6 = y[/tex]

[tex]\frac{3(6) - 24}{ - 2} = x[/tex]

[tex] \frac{18 - 24}{ - 2} = x[/tex]

[tex] \frac{ - 6}{ - 2} = x[/tex]

[tex]3 = x[/tex]

Therefore,

The solution is (3, 6).

Can someone make me a histogram for this set of data. If you do I’ll mark u as the Brainliest

Answers

Answer:On the vertical axis, place frequencies. Label this axis "Frequency".

On the horizontal axis, place the lower value of each interval. ...

Draw a bar extending from the lower value of each interval to the lower value of the next interval.

Step-by-step explanation:

Answer:

Attached is a file of a sample histogram compiled by Social Science Statistics with the values in the question inputted.

Step-by-step explanation:

Histograms are bar graphs that represent a set of values. The vertical y-axis indicate how many values there are in a certain interval, and the horizontal x-axis indicates those intervals, usually in intervals of 10, but this depends on the range of your data.

A histogram with the following forty (40) values:

37, 22, 28, 25, 53, 29, 37, 41, 54, 29, 23, 30, 37, 41, 27, 26, 39, 24, 36, 48, 45, 31, 27, 40, 38, 41, 39, 37, 30, 44, 42, 46, 53, 43, 44, 43, 49, 51, 38, 32

Which shows a quadratic function?

Answers

Answer:

OPTION B IS YOUR ANSWER.

You know its a quadratic when the second difference of each y value is same.

Here's what I mean.

Option B

First all x values differ by 1. So we're good on those.

Now for the y values

Which are

3, -1, -3, -3, -1

find the difference between the second and first fod each... Then do this a second time.

If it gives the same value for all the second differences... Then its quadratic.

-1-3 = -4

-3-(-1) = -3 + 1 = -2

-3-(-3) = -3 + 3 = 0

-1-(-3) = -1 + 3 = 2.

The values are -4, -2, 0, 2.

Now find the difference of these(2nd - 1st)

-2-(-4) = -2 + 4 = 2

0-(-2)= 0 + 2 = 2

2 - 0 = 2

Since all second differences gave 2 as their answer....

Option B is your Quadratic Function!!!

Hope this helps!

You have a $9000 bond that earns 3% interest compounded quarterly. How much is the bond word at 6 years?

Answers

Answer:

$10,667.66

Step-by-step explanation:

The formula for calculating the compound interest is expressed as:

A = P(1+r/n)^nt

P is the principal = $9000

r is the rate = 3%

time t = 6years

n = 1/4

Substitute

A = 9000(1+0.03/(1/4))^6/4

A = 9000(1+0.03(4))^1.5

A = 9000(1+0.12)^1.5

A = 9000(1.12)^1.5

A = 9000(1.1853)

A = 10,667.67

Hence the amount after 6 years is $10,667.66
