Question

How to calculate 3x^2+14x+8=

Solution 1

3x² + 14x + 8

3x² + 12x + 2x + 8

3x(x) + 3x(4) + 2(x) + 2(4)

3x(x + 4) + 2(x + 4)

(3x + 2)(x + 4)

3x² + 12x + 2x + 8

3x(x) + 3x(4) + 2(x) + 2(4)

3x(x + 4) + 2(x + 4)

(3x + 2)(x + 4)

Question

Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. He calculates that the extra money he pays in additional interest each year, if invested at the rate of 2% for one year, could earn him simple interest totaling $180. How much does Benson pay in additional interest each month? a. $360 b. $750 c. $900 d. $1,000

Solution 1

The formula for simple interest is given by

where P is the principal, R is the rate and T is the time.

Let the additional interest Benson pays each year be P, then

Therefore, the additional interest Benson pays each month is given by

where P is the principal, R is the rate and T is the time.

Let the additional interest Benson pays each year be P, then

Therefore, the additional interest Benson pays each month is given by

Question

Geoffrey needs to purchase baseballs and bats for his youth baseball league. He'll need at least 30 pieces of equipment, but he only has $870 to spend. Baseballs cost $20 each and bats cost $35 each. If Geoffrey wants to purchase the most amount of equipment and still stay within his budget, which combination of baseballs and bats is optimal? (21, 9)
(29, 1)
(40, 2)
(33, 6)

Solution 1

21, 9) =21*$20+9*$35=$735

It is at least 30 pieces of equipment, but he can buy more equipment and still be within his budge.

(29, 1) =29*$20+1*$35=$615

It is at least 30 pieces of equipment, but he can buy more equipment and still be within his budge.

(40, 2 ) =40*$20+2*$35=$870

He has more thn 30 pieces of equipment, and he is at his budge.

(33, 6 ) =33*$20+6*$35=$870

He has more thn 30 pieces of equipment, and he is at his budge. This combination is better because it allows him to have more bats available to his team. So this one is optimal.

Question

I don't understand this question. Could anyone excplain to me what it wants me to do and what the answer is? What is the diameter of a sphere that has a surface area of 1041 square inches?
A) 9.1
B) 22.5
C) 40.3
D) 18.2

Solution 1

1st you need equation for the surface area of a sphere which is:

A=4*π*r^2

Where r=radius

r = diameter/2 or d/2

So

area of a sphere = 4*π*(d/2)^2

Plug in the area given

1041 = 4*π*(d/2)^2

Solve for d

1041/(4* π)=82.84

82.84 = (d/2)^2

Sqrt(82.84)=d/2

9.10=d/2

9.10*2= d

18.2=d

So the answer is 18.2 in

A=4*π*r^2

Where r=radius

r = diameter/2 or d/2

So

area of a sphere = 4*π*(d/2)^2

Plug in the area given

1041 = 4*π*(d/2)^2

Solve for d

1041/(4* π)=82.84

82.84 = (d/2)^2

Sqrt(82.84)=d/2

9.10=d/2

9.10*2= d

18.2=d

So the answer is 18.2 in

Solution 2

The answer is 18.2

Question

Wright a real world problem that involves classifying a quadrilateral. Then solve the problem.

Solution 1

An amusement park ride has a moving platform attached to four swinging arms. The platform swings back and forth, higher and higher, until it goes over the top and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC is parallel to the ground (line l). Explain why the moving platform AB is always parallel to the ground.

The shape of quadrilateral ABCD changes as the moving platform swings around, but its side lengths do not change. Both pairs of opposite sides are congruent, so ABCD is a parallelogram by Theorem 8.7.By the definition of a parallelogram, AB DC . Because DC is parallel to line l, AB is also parallel to line l by the Transitive Property of Parallel Lines. So, the moving platform is parallel to the ground.

Question

1. For which angle is secant undefined? a. 30°
b. 45°
c. 180°
d. 270°
2. Which of the following is csc(-166°) equal to?
a. csc(14°)
b. -csc(14°)
c. -csc(-14°)
d. csc(166°)

Solution 1

1. The secant is defined as the inverse function of co-secant or cos function

Hence when the cosine is 0, the secant is 1/0 which is undefined. So, when cosine is 0, secant is undefined

Cos 30 =

Cos 45 =

Cos 180 = -1

cos 270 =0

**Since cos 270 is 0, secant of 270 is undefined**

**Answer is d: 270**

2. cosec (-x) = - cosec (180 -x)

We have cosec(-166) = - cosec (180-14) = -cosec (14)

Alternatively we can confirm this as csc (-166) = -4.133565 and -csc(14) = -4.133565; Hence, we can reconfirm that the answer arrived at is right

Therefore **csc (-166) = -csc(14) (Option B) is the right answer**
