Answer:

It's true, if that's what your asking.

Step-by-step explanation:

5/6 = 0.833 to 3 sig.fig.

4/5 = 0.800 to 3 sig.fig.

6/7 = 0.857 to 3 sig.fig.

What is the midpoint of the segment that joins the complex numbers 7 + 3i and -5 – 8i?
A) 16+11/2i
B) (1,5/2)
C) 1- 5/2i
D) (-6, 11/2)

Answers

Answer:

C)

Step-by-step explanation:

The midpoint is the average of the two points.

Thus,

Midpoint = [ ( 7 + 3i) + (-5 - 8i) ] / 2 = ( (7-5) + i(3-8) ) / 2 = (2 - 5i)/2 = 1 - 2.5i

This is soo hard

Answers

Answer:

100

Step-by-step explanation:

angles CHF and EHI are congruent angles because CD is a straight line.

Therefore EHI must be 20 degrees.

angles DIG and EIH are congruent angles because CD is a straight line.

Therefore EIH must be 60 degrees.

Now that you know two of the three angles in the triangle HEI,

Total degrees in a triangle - EIH - EHI = HEI

180 - 60 - 20 = 100

The answer is -6

Step 1: Simplify both sides of the equation.
(2)(n) + (2)(5) =-2
2n + 10 = -2
Step 2: Subtract 10 from both sides.
2n+10−10=−2−10
2n = -12
Step 3: Divide both sides by 2.

Michael started a savings account. After 5 weeks, he had $340 dollars and after 9
weeks, he had $580. What is the rate of change of money in his savings account per
week?

Answers

Answer:

$60.00 in his savings account per week

Step-by-step explanation:

First, we can convert the information given into points so we can more easily find the rate of change, or slope:

(5, 340) and (9, 580)

Then, we can subtract the y-values and x-values of both, then divide those differences, to find the slope. Remember that the change in y goes on top of the division problem and the change in x goes on the bottom of the division problem:

(580-340)/(9-5) = 240/4 = 60

So, $60 in his savings account per week.

Answer:

he saves 18.45 dollars in each week

b] In the opposite figure : XYZL is a square, XZ = 10 cm. , m(L XZY) = 43° Calculate the perimeter of triangle XYZ ​

Answers

Answer:

Perimeter of Δ XYZ = 24.13

Step-by-step explanation:

In Δ XYZ is a right  triangle because the XYZL is a square.  Therefore the hypotenuse = 10; Looking at the 43° angle, XY is the side that is opposite the 43° angle and the YZ is the side that is adjacent to the 43°.

Using the trig ratios:  

XY = opposite/ hypotenuse which is Sin 43°

Sin 43° = XY/ 10

10(Sin 43°) = XY

 6.82 = XY

YZ = adjacent/hypotenuse which is Cos 43°

Cos 43° = YZ/10

10(cos 43°) = YZ

7.31 = YZ

Now the Perimeter = XY + YZ + XZ

  Perimeter = 6.82 + 7.31 + 10

  Perimeter = 24.13

Answer:

y = 116

w = 116

x = 4

Step-by-step explanation:

a // b  and t is transversal.

y + 64 = 180   {co-interior angles are supplementary}

y = 180- 64

y = 116

w = y     {Alternate interior angles are equal}

w = 116

4x² = 64      {Alternate interior angles are equal}

x² = 64/4

x² = 16

x² = 4²

x = √(4*4)
