Answer:

∠ A ≈ 35.54°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{5}{7}$ , thus

A = $tan^{-1}$ ( $\frac{5}{7}$ ) ≈ 35.54° ( to the nearest hundredth )

Answer:

The formula is 10 - 3n

Step-by-step explanation:

For an nth term in an arithmetic sequence

U( n ) = a + ( n - 1)d

Where n is the number of terms

a is the first term

d is the common difference

From the sequence above

a = 7

d = 4 - 7 = - 3

The formula for an nth term is

U(n) = 7 + (n - 1)-3

= 7 - 3n + 3

The final answer is

= 10 - 3n

Hope this helps you.

What is an equation of the line that passes through the point (-3,-1) and is

Yuri [45]

Answer:

y = -2x - 7

Step-by-step explanation:

x - 2y = 6

-2y = -x + 6

Divide the whole equation by (-2)

$\frac{-2y}{-2}=\frac{-x}{-2}+\frac{6}{-2}\\\\y = \frac{1}{2}x - 3$

slope = 1/2

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

$=(-1)*\frac{2}{1}\\\\= -2$

(-3, - 1)

y -y1 = m(x -x1)

y - [-1] = -2(x - [-3])

y + 1 = -2(x + 3)

y + 1= x* (-2) + 3*(-2)

y + 1 = -2x - 6

y = -2x - 6 - 1

y = -2x - 7
