180-55
125
y= 125°

Answer:

x = 6

y° = 125°

Step-by-step explanation:

9x + 1 and 7x + 13 are alternate angles and has same measurement

9x + 1 = 7x + 13

9x - 7x = 13 - 1

2x = 12

x = 6

y° and 7x + 13 are supplementary angles so their sum is 180°

7x + 13 ➡ 7×6 + 13 = 55°

55 + y° = 180 subtract 55 from both sides

y° = 125°

O 20 units

Answers

By using Pythagoras theorem we can calculate length of YA and which will come out as,  5√3 units, So Option A is correct.

What is  Pythagoras theorem?

It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).

Pythagoras theorem,

H²  =  A² + B²

Given information,

The length of the side YZ is twice of the side AZ,

Given length of side YZ is, 10 unit

Therefore,  length of side AZ is, 5 unit

YA is altitude of ΔXYZ,

and ΔAYZ is a right angle triangle so we use Pythagoras theorem

YZ = H = 10

ZA = A  = 5

YA = B  = ?

100²  =  5² + B²

B = 5√3

Hence, the length of side YA is 5√3  unit

passes through (-2,-2) and is parallel to the line 5x-y=45x

Answers

The equation of the line is y + 40x = -78.

Here, we are given that a line passes through point (-2,-2) and is parallel to the line 5x - y = 45x.

when two lines are parallel their slopes are equal. So, let us first find the slope of  line 5x - y = 45x.

The standard form of the equation of a line is- y = mx + c, where m is the slope of the line.

Here 5x - y = 45x can be written as-

y = -40x

Thus, the slope of the line is -40.

Now we can use the point slope form to find the equation of our line.

According to the point slope form-

(y - y1) = m(x - x1)

here, x1 = -2 and y1 = -2

Thus equation becomes-

(y + 2) = -40 ( x + 2)

y + 2 = -40x - 80

y + 40x = -78

Thus, the equation of the line is y + 40x = -78

The required solution after three successive iterations is near x = 7/8. Option c is correct.

What is the equation?

The equation is the values of two expressions that are equal. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here, we have,

Equation is -2x + 6 = -(2/3)^x + 5. Approximate the solution to the equation above using three iterations of successive approximation.

given that,

-2x + 6 = -(2/3)^x + 5

Arranging the equation

(2/3)^x - 2x + 1 = 0

Since the solution of the equation is when f(x) = 0 at near to  x = 0.8

f(x) = (2/3)^x - 2x + 1

First iteration at x =0.8

f(0.8) = 0.123

It will go up more to get exact zero, so

Second iteration at x = 0.9

f(0.9) = -0.106

It seems that zero is near 0.9 so will go down

The third iteration at x = 0.87

f(0.87) = -0.037

Here , solution is much near to x = 0.87 or x =7/8.

Thus, the required solution after three successive iterations is near x = 7/8.

Answer:

Total distance travel = 8.60 miles

Distance of 1st trail = [tex]5\frac{1}{4}[/tex] miles = 5.25 miles

Distance of 2nd trail = 3.35 miles

Find:

Total distance travel

Total distance travel = 8.60 miles

If John deposits $525 in a savings account and his account pays an annual interest rate of 5.5% and makes no other deposits and withdrawals what is the simple interest earned for 5 years , 5 months , and 5 days

Answers

Answer:

The amount of simple interest earned is $156.79

Step-by-step explanation:

Mathematically;

Simple interest = PRT/100

From the question;

P = $525

R = 5.5%

T ; to get this, we need to make the numbers agree;

We do this by dividing number of months by 12 and number of days by 365

So 5 years, 5 months and 5 days will be;

5 + 5/12 + 5/365 = 5.43

So, using this in the simple interest calculations, we have;

S.I = (525 * 5.5 * 5.43)/100

S.I = $156.79

Marisha wants to measure the volume of a rock. She pours water into a graduated cylinder and it measures 200 mL. Then she drops the rock in it, and measures the water level at 297.5 mL. The volume of the rock is the difference between the water level before and after. What is the volume of the rock

Answers

Answer:Volume of Rock= 97.5ml

Step-by-step explanation:

STEP 1

Finding  the volume of rock using  the graduated cylinder that measures volume of liquid can be  done by determining how much water is being displaced by the rock after submersion.

Step 2

Volume of water  before adding rock = 200mL

Volume of water after adding the rock = 297.5mL

Volume of rock =Volume of water after adding the rock - Volume of water  before adding rock

Volume of Rock = 297.5-ml 200ml

= 97.5ml

Samuel and Savannah purchase stocks in a company. Samuel started with 50 shares and of the stock and buys 10 shares per month. Savannah did not start with any shares, but she buys 25 shares per month. Write an equation that represents the number of months it will take before Savannah and Share the same amount of shares

Answers

Answer:

50 + 10m = 25m

Step-by-step explanation:

Given that:

Samuel:

Stating shares = 50 shares plus 10 shares per month

Savanah :

Starting shares = 0 plus 25 shares per month

Let number of months = m

Samuel shares = savanna shares

50 + 10m = 25m

50 = 25m - 10m

50 = 15m

50 / 15 = m

Write the simplest polynomial function with the given roots 1/2,5, and -2

Answers

Answer:

x³-7x²/2-39x/2 + 10

Step-by-step explanation:

Given 1/2,5, and -2 as roots of the polynomial, the function in terms of x is expressed as;

P(x) = (x - 1/2)(x - 5)(x+2)

Expand;

(x - 1/2)(x - 5) = x²-5x -x/2 + 5/2

(x - 1/2)(x - 5) = x²-11x/2 + 5/2

P(x) = (x²-11x/2 + 5/2)(x+2) = x³+2x²-11x²/2-22x+5x/2 + 10

P(x) = x³-7x²/2-39x/2 + 10

Hence the required polynomial is x³-7x²/2-39x/2 + 10
