Answer:

Step-by-step explanation:

It's helpful to draw it out, but you need a calculator for this.

You have the values of line b, line c, and angle C.

You can use sinC / c since you have C and c.

Solve for sinB by doing sinB/5.7 = sinC/8.6

you'll get the value of sinB, use inverse trig to solve for B (sin^-1)

Then you'll have the angle values for C and B. Add them, and subtract by 180 to find the angle measure of A.

Use the steps above to find a:

sinA (which u just found) / a = sinC (125) / c (8.6)

Hope this helps.

Answer:

The required equation $k-2=\dfrac{1}{9}(t-18)$

C should be correct.

Step-by-step explanation:

Given: Julissa is running a 10-kilometer race at a constant pace.

After running for 18 minutes, she completes 2 kilometers.

First point: (18,2)

After running for 54 minutes, she completes 6 kilometers.

Second Point: (54,6)

We need to write an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable

Using two point formula to find the equation of line

Formula:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Required Equation:

$k-2=\dfrac{6-2}{54-18}(t-18)$

$k-2=\dfrac{4}{36}(t-18)$

$k-2=\dfrac{1}{9}(t-18)$

Hence, The required equation $k-2=\dfrac{1}{9}(t-18)$

write an equation in slope-intercept form for the line that is perpendicular to -2x-8y=16 and that passes through (4,5)

mash [69]

Slope of line perpendicular to ax+by=c is b/a

given
-2x-8y=18
slope of perpendicular is -8/-2=4

y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b

y=4x-15
