Answer:

d = 5 m

Step-by-step explanation:

The diagonal divides the rectangle into 2 right triangles with legs 3 and 4 and hypotenuse h

Using Pythagoras' identity in one of the right triangles, then

d² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )

d = $\sqrt{25}$ = 5

Answer:

Step-by-step explanation:

We know that a^2+b^2=c^2 from the Pythagorean theorem where a and b are the legs and c is the hypotenuse

4^2+3^2 = c^2

16+9 = c^2

25 = c^2

Taking the square root of each side

sqrt(25) = sqrt(c^2)

5 =c

Find the interest earned if you place $76.43 into an account that pays 21.5% simple interest, and leave it in for 3 years.

o-na [289]

A = $125.73

I = A - P = $49.30

hey!

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 21.5%/100 = 0.215 per year.

Solving our equation:

A = 76.43(1 + (0.215 × 3)) = 125.72735

A = $125.73

The total amount accrued, principal plus interest, from simple interest on a principal of $76.43 at a rate of 21.5% per year for 3 years is $125.73.

Answer: Answer is x = 5, y = -3

(5, -3)

Step-by-step explanation: The instruction is to use the substitution method, and from the first equation,

y = x - 8

This means we replace the value of y in the second equation with x - 8. Hence;

2x + 3y = 1 can now be re-written as

2x + 3(x - 8) = 1

2x + 3x - 24) = 1

5x - 24 = 1

Add 24 to both sides of the equation

5x -24 + 24 = 1 + 24

5x = 25

Divide both sides of the equation by 5

x = 5

Having calculated x as 5, we can now substitute for the value of x in the first equation

y = x - 8 now becomes

y = 5 -8

y = -3

The depreciating value of a semi-truck can be modeled by y = Ao(0.85)x, where y is the remaining value of the semi, x is the tim

I've answered this question before, my answer was:

y = Ao(0.85)x

B. $75,000, and the graph would have a y-intercept at 65,000

Based on the graph, when x = 0 ; y = 75,000

If the initial value will be 65,000 instead of 75,000, then the y-intercept is 65,000.

The rate of the same all throughout. It is still depreciating at 15% per year.
