Mathematics
1 answer:
deff fn [24]4 years ago
3 0

Answer:

I=Prt

Step-by-step explanation:

The simple interest formula is given as;

          I  = Prt

where I is the simple interest

           p is the principal

           r is the percentage rate

          t is the duration

Simple interest accrues on the principal of either a loan or an investment. This amount is payable after a duration of time.

Principal is the amount borrowed or invested in a business

Rate is the percentage commission to be paid on the amount borrowed

Time is the duration of the borrowing.

The measure of the vertex angle of an isosceles triangle is 64 what is the measure of each base angle
zavuch27 [327]

Answer:

58

Step-by-step explanation:

For every triangle, all angles add up to 180. So you have to subtract 64 from 180 which gives you 116. You then take that number and divide it by two because there are two base angles, which gives you 58. The answer is 58.

Plz helppp: Identify the graph of the equation. What is the angle of rotation for the equation? 21x^2-8√3 xy+13y^2=225
GREYUIT [131]

Answer:

The correct option is C.

C) ellipse, -30°

Step-by-step explanation:

General form of equation for a conic section is:

(A)x² + (B)xy + (C)y² + (D)x + (E)y + F = 0

The equation of the conic section is given:

21x² - (8√3)xy + 13y² = 225

21x² - (8√3)xy + 13y² - 225 = 0

Which can be rewritten as:

(21)x² + (-8√3)xy + (13)y² + (0)x + (0)y + (-225) = 0

where

A = 21

B = -8√3

C = 13

D = 0

E = 0

F = -225

Consult the table below.

As A ≠ C and and AC > 0 , the equation represents an ellipse

The angle of rotation can be found by following equation:

cot(2θ) = (A - C)/B

cot(2θ) = (21 - 13)/(-8√3)

2θ = cot⁻¹(8/-8√3)

2θ = 120°

θ = 60° (from x-axis)

As the major axis of ellipse lies on y-axis, axis of rotation from y-axis is

θ = -30°

A fence is to be built to enclose a rectangular area of 220 square feet. The fence along three sides is to be made of material t
VikaD [51]

Answer: a rectangle is a quadrilateral having opposing sides parallel and four right angles

Area of rectangle = length * width

Step-by-step explanation: Given Area of rectangle = 220 square foot

1 side of the fence = 220/4 = 55 feet

If 3 sides of the fence cost $3

Total cost for 3 sides of the fence = ( 55 + 55 + 55) * 3 = 165 * 3 = $495

Total cos for the 4th side = 55 * 13 = $715

It is more economical to construct the fence with materials that cost $3.
