Hector = 2s or h/2
Sister = s


Equation: h/2 = s

Substitution: (20)/2 = s

10 = s


Hector’s sister found 10 seashells.

In ΔTUV, the measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet. Find the length of TU to the nearest tenth of a foot.
Degger [83]

<u>Given</u>:

Given that TUV is a right triangle with measure of ∠V=90°

The measure of ∠U = 55°, and the length of VT is 82 feet.

We need to determine the length of TU.

<u>Length of TU:</u>

The length of TU can be determined using the trigonometric ratio.

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

where \theta=55^{\circ}, opp = VT and hyp = TU

Thus, we have;

sin \ 55^{\circ}=\frac{VT}{TU}

Substituting the values, we have;

sin \ 55^{\circ}=\frac{82}{TU}

Simplifying, we have;

TU=\frac{82}{sin \ 55^{\circ}}

TU=\frac{82}{0.819}

TU=100.1

Thus, the length of TU is 100.1 feet.

Which of the following is the equation of the line that is parallel to y=35x+8 y = 3 5 x + 8 and goes through point (-10,4)?
xeze [42]

Slope-intercept form of a line is y=mx+b.

Where m= slope and b= y-intercept.

First step is to compare the given equation y=35x+8 with the above equation to get the value of m.

After comparing the two equations we will get m=35.

Slope of paralle lines always equal which means slope of a line which is parallel to the above line will also be 35.

Now the line is passing through (-10,4).

Point slope form of a line is :

y-y_{1} =m(x-x_{1} )

Next step is to plug in m=35, x1=-10 and y1=4 in the above equation. So,

y-4=35(x-(-10)

y-4=35(x+10)

y-4=35x+350

y=35x+350+4

y=35x+354.

So, the equation of the line is y=35x+354.

Graph the function
Assoli18 [71]

Answer:

see below for a graph

Step-by-step explanation:

The equation is in slope-intercept form, so right away you know one point is the y-intercept: (0, -4).

Another point can be found using the slope, which is 3/2, to go 2 units to the right and 3 units up. (Slope = rise/run, so rise = 3 and run = 2 match the slope.)
