What is the slope of the line − 3 3?

Answer:

y = 300x + 100

Step-by-step explanation:

y = mx + c

the line intersects the y axis at 100, so c = 100

m = difference between y-coordinates / difference between x-coordinates

m = (400-100)/(1-0) = 300/1 = 300

y = 300x + 100

The side JE is equal to side IE because all the sides of the square are congruent.

It is a polygon with four sides. The total interior angle is 360 degrees. In a square, all the sides of the square are equal and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

JH is opposite to JE and Hello is opposite to IE. Also, JH is congruent with HE.

Let 'm' be the side of the square.

HI = JE         (Congruent)

HJ = IE         (Congruent)

∠H = ∠J = ∠I = ∠E = 90°

Then the shape that is defined will be a square.

The side JE is equal to side IE because all the sides of the square are congruent.

Answer:

width = 6 cm

Step-by-step explanation:

Area = width x length

let x = length

width = x - 6

A = 72 cm² = x(x-6) =  x² - 2x

rewrite the equation:

x² - 2x - 72 = 0

solve for x by factoring or the quadratic equation:

(x-12)(x+6) = 0

x = 12, -6

therefore x = length = 12

Width = 12 - 6 = 6

Answer:

To calculate Nora's total annual interest on her $800 investment, we can use the following formula:

Interest = Principal x Rate x Time

In this case, the principal is $800, the rate is 6% per annum, and the time is 1 year. Plugging these values into the formula, we get:

Interest = $800 x 0.06 x 1

To convert the 6% rate to a decimal, we divide 6 by 100. This gives us 0.06. We then multiply the principal by the rate and the time to get the total annual interest. So the total annual interest on Nora's $800 investment is:

Interest = $800 x 0.06 x 1 = $48

Therefore, Nora will earn a total of $48 in interest on her $800 investment over the course of one year at a rate of 6% per annum.

Step-by-step explanation:

Given that the hoop makes one complete oscillation in 2s, this implies that the period of oscillation is 2s

Then,

T = 2s

Let the Mass of the thin hoop be M

Let the Radius of the hoop be R

The moment of inertial of a hoop is

I = MR²

The period of a physical pendulum of small amplitude is given by

T = 2π √(I / Mgd)

Where,

T is the period in seconds

I is the moment of inertia in kgm²

M is the mass of the hoop

g is the acceleration due to gravity

g = 9.8m/s²

d is the distance from the rotational axis to the center of gravity

Therefore, d = R

Then, applying the formula

T = 2π √ (I / MgR)

So, we know that

I = MR²

Then,

T = 2π √( MR² / MgR)

T = 2π √(R/g)

Make R the subject of the formula

Square both sides

T² = 4π²(R/g)

T²g = 4π²R

Then, R = T²g / 4 π²

Since g = 9.8m/s² and T= 2s

R = 2² × 9.8 / 4π²

R = 0.993m

Then, the radius of the hoop is 0.993m

The height of the top section of the tower is 32 feet.

The radio station tower is built in two sections. The tower is 87 feet from the viewing point. The angle of elevation of the bottom section is 25 degrees. The angle of elevation from the top of tower (both sections) is 40 degrees. Let the height of the bottom section be y and height of the bottom and top section be z.

Considering a right-angled triangle, tangent formula states that:

Tan ɵ = opposite side/ adjacent side where ɵ is the angle of elevation.

Hence, when ɵ = 25, opposite side = y, and adjacent side = 87

Tan 25 = y/ 87

y = 40.57 feet

Hence, when ɵ = 40, opposite side = z, and adjacent side = 87

Tan 40 = z/87

y = 73 feet
