Answer 1

Answer:

Answer: C. 7x^2+4x-5

Step-by-step explanation:

Add as you would normally. Exponents can look scary but don’t mind them. First add 5x^2 & 2x^2 to get 7x^2. Then do -5x + 9x. An easier way of doing that would be 9x-5x to get 4x. Lastly do 1 -6 to get 5.

What is the measure of AC?
Enter your answer in the box. Enter only the numerical value.

Answers

Step-by-step explanation:

Angle BDC is an angle inscribed in a circle. As such it intercepts TWICE as many degrees of arc as its measure

so: 2 * (3x-1.5) = 3x+9

6x -3 = 3x+9

x = 4

then the arc AC = 3x+9 = 21 degrees

A golf ball is hit with an initial velocity of 50 m/s at an angle of 45° above the horizontal. What's the maximum height it will reach?a. 35.4 m
b. 63.5 m
c. 82.1 m
d. 127.0 m

Answers

This problem is a projectile problem. The initial velocity is 50m/s at an optimum angle of 45. The maximum height or the height of the y component is at it's highest is asked.

Informtion needed:
Acceleration due to gravity = 9.81m/s^2

Formula:

Hmax = ((V^2)(sin(angle))^2)/2g
Hmax = ((50^2)(sin45)^2)/(2*9.81) = 63.71 or letter B 63.5 m is the closest answer.

An apple pie has a 12-inch diameter and the angle of one slice is 60 degrees. What is the area of that slice of pie? Use 3.14 as the value of pi .

Answers

r = 6 in;
60° = 1/6 · 360°
The area of the slice of pie:
A = 1/6 · r² · π
A = 1/6 · 6² · 3.14 = 18.84 in²

An apple pie has a 12-inch diameter and the angle of one slice is 60 degrees. What is the area of that slice of pie?

Answer: This problem is simple. To find the area of that slice of pie we will need to do the following: radius = diameter / 2. Therefore by replacing the values we will get 12 /2 = 6. Finally we use this formula and solve for the answer Area = πr²Θ / 360. The correct answer you should get is 18.84 in².

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Let the cost of pencil box be x

Let the cost of notebook be y

Total cost = $6.28

⇒ $x+y = 6.28 ----- (1)$
