Step-by-step explanation:

Given,

Angle ADC = 118°

According to the question

11x - 7 + 5x - 3 = 118

=  > 11x   - 7 + 5x = 118 + 3

=  > 11x + 5x = 121 + 7

=  > 16x = 128

= x =  \frac{128}{16}

=  > x = 8

Now let's find the value of angle ADB

In the question it is mentioned that Angle ADB = (11x - 7)°

We know that x = 8 °

<h3 /><h3 /><h3>so let's get into this sum :)</h3>

Angle ADB = (11x - 7)°

= (11 × 8 - 7)°

= (88-7)°

= 81 °

So the answer is the first option i.e. 81°.

HOPE IT HELPS YOU!!

Write the equation of the line that passes through the
Butoxors [25]

Answer: y = 2x also written as y = 2x + 0

Step-by-step explanation:

When dealing with parallel lines their slopes are ALWAYS the same so the equation would have the slope of 2, but to find the y intercept you have to plug the coordinate given into the point-slope formula (y - y1) = m(x - x1) where m is the slope, y1 is the y output of the coordinate and x1 is the x input of the coordinate.

1. Plug cordinate into point slope form equation:

(y - 0) = 2(x - 0)

2. Distribute the 2 to x and 0

y - 0 = 2x - 0

The two zeros cancel out because they are 0s to begin with so your final answer for your y - intercept is 0

hope this helps :)

5) Paul invests $3,092 in a savings account
Mkey [24]

Answer:

R = 5% per year

Step-by-step explanation:

Solving for rate r as a decimal

r = n[(A/P)^1/nt - 1]

r = 4 × [(4,835.71/3,092.00)^1/(4)(9) - 1]

r = 0.05

Then convert r to R as a percentage

R = r * 100

R = 0.05 * 100

R = 5%/year

Summary:

The interest rate required to get a total amount of $4,835.71 from compound interest on a principal of $3,092.00 compounded 4 times per year over 9 years is 5% per year.

To divide complex numbers, you multiply by the conjugate. The conjugate is when you change the sign between the two terms in the denominator. Therefore, the conjugate in this one is (3+i)


\frac{13-i}{3-i} * \frac{3+i}{3+i} ← Then, you foil these guys:


\frac{(13-i)(3+i)}{(3-i)(3+i)} = \frac{40+10i}{10} = 4 + i or C
