What is the measure of angle c
A)35
B)60
C)110
D)120

Answer:

graph A.

Step-by-step explanation:

So, y = 1/2x - 2 is only graphed in A and D.

And x ≤ 6 is only graphed in graph A.

The graph of the piecewise function is the first graph (counting from the top).

Here we have a piecewise function:

f(x) = 0.5*x - 2  if x ≤ 6

f(x) = -x - 1   if x > 6

So, we have an increasing line for x smaller or equal than 6, and a decreasing line for x > 6. Such that we should to have a closed dot at the end of the increasing line, because in that part we have the symbol ≥, meaning that x = 6 belongs to that part.

Then the correct graph is the first option.

How to Find the Mean

Add up all data values to get the sum

Count the number of values in your data set

Divide the sum by the count

The mean is the same as the average value in a data set.

We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.

We have two angles and opposite sides to these angles.

We will use Law of Sines to solve our given problem.

[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where a, b and c are opposite sides corresponding to angles A, B, and C respectively.

The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.

Upon substituting these values in Law of Sines, we will get:

[tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex]

Therefore, our required equation would be [tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex].

Answer:

(-4,1)

Step-by-step explanation:

Ordered pair (-4,1) means that x = -4 and f(x) = 1

Ordered pair (1,-4) means that x = 1 and f(x) = -4

From the table, we can see that the function is already defined for x = -4, but it is not defined for x = 1. So, the point (1,-4) can be included into the function, but the point (-4,1) cannot.

Answer:

sin (theta) = [tex]\frac{\sqrt{15} }{8}[/tex]

cos (theta) = [tex]\frac{7}{8}[/tex]

Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of

[tex]B=12 \times 12 = 144 \ in^{2}[/tex]

The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face

[tex]A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}[/tex]

But there are four triangle faces, so [tex]A_{faces} =4(66)=264 \ in^{2}[/tex].

Therefore, the area of each triangular face is 66 square inches.

So, the total surface area would be the sum

[tex]S=144+264=408 \ in^{2}[/tex]

Therefore, Gabriel needs 408 square inches to paint the whole model.

The range is 96.

Step-by-step explanation:

The definition of range is "The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set." So subtract the highest value from the smallest value,  and you get 96. pls mark brainliest.

so it's 4 and 100

we substract the smallest from the biggest number :

100 - 4 = 96

Answer:

$2600 was invested on the 1% account while $2400 was invested on the 6% account.

Step-by-step explanation:

For simple interest we must apply the following formula:

M = C*r*t

Where M is the amount of interest generated, C is the invested money, r is the rate of interest and t is the elapsed time.

The sum of capital investead in each account, "x" for the 1% interest one and "y" for the 6% interest one, must be equal to the original $5000. The same way as the interest generated from these investments must be equal to the earnt $170. So we have:

x + y = 5000

For the first account:

M1 = x*0.01*1 = 0.01*x

For the second account:

M2 = y*0.06*1 = 0.06*y

The sum of interests:

0.01*x + 0.06*y = 170

We have a system of equations as shown below:

x + y = 5000

0.01*x + 0.06*y = 170

Multiplying the first equation by -0.01 and adding both equations we have:

-0.01*x - 0.01*y = -50

0.01*x + 0.06*y = 170

0.05*y = 120

y = 120 / 0.05 = $2400

x = 5000 - 2400 = $2600

$2600 was invested on the 1% account while $2400 was invested on the 6% account.

Let s represent the number of sofas and e  represent the amount earned.

We have been given that Mr. Gilmore sells furniture. He earned $210 for selling 3 sofas. Mr. Gilmore  earned $570 for selling 11 sofas. We are asked to write the equation for given scenario.

We have two points on a line that are (3,210) and (11,570).

Let us find slope of line passing through these points.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{570-210}{11-3}[/tex]

[tex]m=\frac{360}{8}[/tex]

[tex]m=45[/tex]

Now we will use point-slope form of equation.

[tex]y-y_1=m(x-x_1)[/tex], where

m = Slope,

[tex](x_1,y_1)[/tex] = Any point on line.

[tex]y-210=45(x-3)[/tex]

[tex]y-210=45x-135[/tex]

[tex]y-210+210=45x-135+210[/tex]

[tex]y=45x+75[/tex]

Since amount earned is e and number of sofas is s, so our equation would be [tex]e=45s+75[/tex].

Therefore, our required equation would be [tex]e=45s+75[/tex].

Hey there!

Since these angles share the same vertex (point where the lines that make the angle meet), they are congruent (they have the same value). Therefore, we can write the following equation.

4x-12=2x+48

We add 12 to both sides.

4x=2x+60

We subtract 2x from both sides.

2x=60

We divide both sides by 2.

x=30

Now, we can plug this in to find the measure of angle ACB. Whenever you see an angle that is named with three letters, the middle one is its vertex and the other two are the end points.

m∠ACB=4(30)-12

m∠ACB=120-12

m∠ACB=108
