The length of the rectangle shown below is represented by the expression (x - 2)2. The width is represented by the expression (3x - 5). What is the area of the rectangle?

Answers

Answer:

(6x² - 22x + 20) square units

Step-by-step explanation:

The area of a rectangle is calculated as:

Length × Width

From the question

Length = (x - 2)2 = 2x - 4

Widths = 3x - 5

The area of the rectangle =

(2x - 4 ) × (3x - 5)

2x(3x - 5) -4(3x - 5)

6x² - 10x - 12x + 20

6x² - 22x + 20

The area of the rectangle =

(6x² - 22x + 20) square units

To check which set does not make a right triangle, let us check if each set is a Pythagorean triplet:

A) 3, 4, 5
(3)^2+(4)^2=(5)^2
= 9+16=25
= 25=25

B) 5, 12, 13
(5)^2+(12)^2=(13)^2
= 25+144=169
= 169=169

C) 9, 40, 41
(9)^2+(40)^2=(41)^2
= 81+1600=1681
= 1681=1681

D) 7, 8, 15
(7)^2+(8)^2=(15)^2
= 49+64=225
= 113≠225

Thus, the set of side measures 7, 8, 15 does not form a Pythagorean Triplet, and thus not a right triangle.

(please help!)Abigail invested $2,900 in an account paying an interest rate of 2.8% compounded
quarterly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $4,050?

Answers

Answer:

Step-by-step explanation:

4050 = 2900 (1 + 0.028/4)^4t

4050 = 2900 (1.007)^4t

Divide all by 2900

1.3965517 = 1.007^4t

TURN LOG

log (1.3965517) = log (1.007^4t)

47.8819724 = 4t

11.9704931 = t

Round to nearest year = 12

T = 12

What is the volume of a spherical water balloon with a radius of 6 inches?

Answers

Answer:

288πin³

Step-by-step explanation:

Volume of a sphere is expressed as;

V = 4/3πr³

r is the radius = 6 inches

Substitute into the formula

V = 4/3π(6)³

V = 4/3π(216)

V= 864/3π

V = 288π in³

Hence the volume of the sphere is 288πin³

On a map with a scale of 1 inch= 100 miles, the distance between two cities is 7.55 inches. If a car travels 55 miles per hour, about how long will it take to get from one city to another.

Answers

Answer:

13.73 hours

Step-by-step explanation:

On a map with a scale of

1 inch= 100 miles

the distance between two cities is 7.55 inches.

We convert from inches to miles

1 inch = 100 miles

7.55 inches = x

x = 7.55 × 100 miles

x = 755 miles

The distance between the two cities = 755 miles

If a car travels 55 miles per hour, about how long will it take to get from one city to another?

We are to calculate the Time

Speed = Distance /Time

Time = Distance/Speed

Hence, the time is calculated as:

755 miles/55 miles per hour

= 13.727272727 hours

≈ 13.73 hours
