Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (4, 1.2)

Point (10, 6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $\displaystyle m=\frac{6-1.2}{10-4}$
Subtract: $\displaystyle m=\frac{4.8}{6}$
Divide: $\displaystyle m=0.8$

laws of Sines with find the angle. Find each measurement indicated. Round your answers to the nearest tenth. Show your work plea

Gwar [14]

Answer:

4. Z ≈ 46.1°

5. T ≈ 45.2°

6. F ≈ 15.0°

Step-by-step explanation:

We need to use the Law of Sines, which states that for a triangle with legnths a, b, and c and angles A, B, and C:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, we can say that ZY = a = 30, X = A = 110, XY = b = 23, and Z = B. Plug these in to find Z:

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{30}{sin(110)} =\frac{23}{sinZ}$

Solve for Z:

Z ≈ 46.1°

Use the Law of Sines as above.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{26}{sin(76)} =\frac{19}{sinT}$

Solve for T:

T ≈ 45.2°

Again, use the Law of Sines as before.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{29}{sin(137)} =\frac{11}{sinF}$

Solve for F:

F ≈ 15.0°

Which shapes can the composite figure be divided into to find the area

icang [17]

Given:

Composite figure

To find:

The shapes in the composite figure.

Solution:

The image splitted into three shapes.

Draw a line from top vertex to bottom vertex.
We get one triangle.
Similarly, draw another line adjacent to the previous line.
We get another triangle and rectangle.

Therefore a composite figure divided into a rectangle and two triangles.

Landon is standing in a hole that is 5.1 ft deep. He throws a rock, and it goes up into the air, out of the hole, and then lands

AysviL [449]

The rock will hit the ground when y=0, so we need to solve this equation for its roots. To do that, we set it equal to 0:
$0=-0.005x^{2}+0.41x-5.1$

Divide everything by -0.005 to clear out the decimals:
$0=x^{2}-82x+1020$

Now use the quadratic formula:
$x=\frac{82 \pm \sqrt{82^2-4*1020}}{2}$
$x=15.29$ or $x=66.71$
We want the larger x value since the smaller one is when the rock will reach the top of the hole.
