Answer:

sin A = 9/41

cos A = 40/41

tan A = 9/40

Step-by-step explanation:

sin A = opp/hyp = a/b = 9/41

cos A = adj/hyp = c/b = 40/41

tan A = opp/adj = a/c = 9/40

Enter the equation of the line in slope-intercept form.
ad-work [718]

Answer:

y = \frac{7}{4}x +14

Step-by-step explanation:

Given

y = \frac{7}{4}x + 4

Required

Determine the equation of line that passes through (-8,0) and parallel to y = \frac{7}{4}x + 4

Parallel lines have the same slope.

In y = \frac{7}{4}x + 4

The slope, m is

m = \frac{7}{4}

because the general form of a linear equation is:

y = mx + b

Where

m = slope

So, by comparison:

m = \frac{7}{4}

Next, is to determine the equation of line through (-8,0)

This is calculated using:

y - y_1 = m(x - x_1)

Where

m = \frac{7}{4}

(x_1,y_1) = (-8,0)

So, we have:

y - 0 = \frac{7}{4}(x -(-8))

y - 0 = \frac{7}{4}(x +8)

y - 0 = \frac{7}{4}x +\frac{7}{4}*8

y - 0 = \frac{7}{4}x +7*2

y - 0 = \frac{7}{4}x +14

y = \frac{7}{4}x +14

Convert 0.875 inch to a fraction in simplest form.
worty [1.4K]
0.875 in fraction.
to convert it into fraction you have to divide it by 1000 to remove decimal.
so we get,
 875/1000 = 7/8 
7/8 is the simplest form of 0.875 or 875/1000
