pls help?

Answers

Answer:

X = -4

Step-by-step explanation:

91x + 637 =273

First subtract 637 from both sides: 91x = -364

Then, divide both sides by 91 to get X by itself: X = -4

Hopes this helps:

Answer: -4

91x= 273- 637

91x= -364

X= -364/91

X= -4

A 34-foot tall utility pole is supported by two wires that are anchored 8feet from the base of the pole.how many feet of wire is needed for the support wires?

Answers

Answer:

35 feet

Step-by-step explanation:

The problem is a right angle triangle problem and we have to solve it using pythagoras theorem

Let the length of the wire be x

So;

x^2 = 34^2 + 8^2

x = √34^2 + 8^2

x = 35 feet

If the simple interest on $8000 for 3 years is $540, what is the rate of interest per annum?​

Answers

Answer:

2.25%

Step-by-step explanation:

I = Prt

Given:

I = 540

P = 8000

t = 3

Solve for r:

I = Prt

r = I/(Pt)

r = 540/(8000 * 3)

r = 540/24000

r = 0.0225

Rate in percentage form:

0.0225 * 100 = 2.25%

Do the following setm of lengths form a right triangle 36,77, 85

Answers

Answer:

They can make a right traingle because both sides of the equation are equal these lengths do form a right triangle.

Answer:

yes

Step-by-step explanation:

Using the converse of Pythagoras' identity

If the square of the longest side is equal to the sum of the squares of the other 2 sides then triangle is right.

longest side = 85 and 85² = 7225

36² + 77² = 1296 + 5929 = 7225

Thus the 3 sides form a right triangle

Identify the center and radius of the circle with the following equation: [tex]\displaystyle(x+3)^2+(y+\frac{3}{2})^2=4[/tex]

Answers

Hey there,

The equation is already written in circle equation form but if needed, here is what it will look like when it isn't simplified.

(x - (-3))² + (y - (-3/2))² = 2²

With this, the circle has a center at (-3, -3/2) and a radius of 2.

Best of Luck!

Step-by-step explanation:

Hey there!

Given;

The equation of a circle is:(X+3)² + (y+3/2)² = 4.

Comparing the equation with (x-h)²+(y-k)² = r², we get;

Centre (h,k) = (-3,-3/2)

Radius (r) = 2 units.

Hope it helps!
