Answer:

<h2><u>Graph A. </u></h2>

Step-by-step explanation:

Since you are looking for a graph that shows a function, answer A has to be correct. If you look at graph B, C and D, none of these are functions

You can check if a graph shows a function using the vertical line test. Make a vertical line on any x value and if it passes through 2 or more lines, it is NOT a function

Find the measure of each angles: <br>

sineoko [7]

Answer:

10. 123º

13. 65º

Step-by-step explanation:

For number 10, a straight line is equal to 180º so all we have to do is subtract 57 (the number that we're given) from 180

For number 13, vertical angles are always congruent (the same) so we know that it's 65º

Find the perimeter of the polygon. Round your answer to the nearest tenth.

lakkis [162]

Answer:

Option B.

Step-by-step explanation:

From the given figure it clear that the the vertices of the polynomial are Q(2,0), R(4,5), S(8,7), T(6,4) and U(10,3).

Distance formula:

$d=\sqrt{(x-2-x_1)^2+(y_2-y_1)^2}$

Using distance formula, we get

$QR=\sqrt{\left(4-2\right)^2+\left(5-0\right)^2}=\sqrt{29}$

$RS=\sqrt{\left(8-4\right)^2+\left(7-5\right)^2}=2\sqrt{5}$

$ST=\sqrt{\left(6-8\right)^2+\left(4-7\right)^2}=\sqrt{13}$

$TU=\sqrt{\left(10-6\right)^2+\left(3-4\right)^2}=\sqrt{17}$

$QU=\sqrt{\left(10-2\right)^2+\left(3-0\right)^2}=\sqrt{73}$

Now, the perimeter of the polynomial is

$Perimeter=QR+RS+ST+TU+QU$

$Perimeter=\sqrt{29}+2\sqrt{5}+\sqrt{13}+\sqrt{17}+\sqrt{73}$

$Perimeter=26.12996$

$Perimeter\approx 26.1$ units.

Therefore, the correct option is B.

Julie has 1 and 3/4 gallons of juice, and she wants to pour it into 4 equally-sized pitchers. How many gallons will each pitcher

OLga [1]

Just divide the amount of gallons by 4:

1 3/4 = 7/4

(7/4)/4 = 7/16

Each pitcher will have 7/16 gallons.

Question is stated in picture. The figure is a triangular piece of cloth

Anastasy [175]

Answer:

Alternative D - 8 sin(35°)

Step-by-step explanation:

Sin(x) is defined as:

$\begin{gathered} \sin (x)=\frac{\text{Opposite side}}{Hypotenuse\text{ }} \\ \end{gathered}$

In this exercise,

BC is the opposite side to 35°

AC is the hypotenuse and measures 8 in

Then:

$\begin{gathered} \sin (35\degree)=\frac{BC}{8} \\ \sin (35\degree)\cdot8=BC \\ BC=8\sin (35\degree) \end{gathered}$

Express 5.03 as a fraction.

algol [13]

<em>Convert the mixed number 5 3 100 into an improper fraction first by multiplying the denominator ( 100 ) by the whole number part ( 5 ) and add the numerator ( 3 ) to get the new numerator. Place the new numerator ( 503 ) over the old denominator ( 100 ) . 503 /100 .</em>
