What is 3÷269, 4÷195, 6÷249, 7÷186, 9÷198, 3÷208

The number A of tablet computers sold (in millions) can be modeled by the function A=4.5t2+43.5t+17 , where t represents the num

Rina8888 [55]

The problem indicates that A represents the number of tablet computers sold in millions. So, if 65 million were sold, we must substitute A = 65 to the equation. Then, we find for t.

65 = 4.5t² +43.5t + 17
Solving for t using a calculator,
t = 1 and -10.67

Let's take the positive root. So, t=1.
That means the year would be 1 year after 2010. Therefore, the answer is 2011.

The perimeter of a triangle is 47 feet. One side of the triangle is one foot longer than the second side. The third side is four

Ugo [173]

Answer:

The lengths of all three sides (in feet) are = 15, 14, and 18 feet

Step-by-step explanation:

Perimeter of Triangle = 47ft

Let the one side be 'x'

Side 1 = x

One side of the triangle is one foot longer than the second side

Side 2 = x - 1

The third side is four feet longer than the second side

Side 3 = (x - 1) + 4

Perimeter = sum of all sides

47 = x + (x - 1) + (x - 1) + 4

47 = x + x - 1 + x - 1 + 4

47 = 3x + 2

47 - 2 = 3x

45 = 3x

x = 15

substitute for x in each of the sides

Side 1 = x => 15 feet

Side 2 = x - 1 => 15 - 1 = 14 feet

Side 3 = (x - 1) + 4 => 14 + 4 = 18 feet

Find all solutions to the equation:

crimeas [40]

Let z = sin(x). This means z^2 = (sin(x))^2 = sin^2(x). This allows us to go from the equation you're given to this equation: 7z^2 - 14z + 2 = -5

That turns into 7z^2 - 14z + 7 = 0 after adding 5 to both sides. Use the quadratic formula to solve for z. The only solution is z = 1 (see attached image). Since we made z = sin(x), this means sin(x) = 1. All solutions to this equation will be in the form x = (pi/2) + 2pi*n, which is the radian form of the solution set. If you need the degree form, then it would be x = 90 + 360*n

The 2pi*n (or 360*n) part ensures we get every angle coterminal to pi/2 radians (90 degrees), which captures the entire solution set.

Note: The variable n can be any integer.

A company's current stock price is $50.00 and its most recent dividend was $2.00 per share. Since analysts estimate the company

4vir4ik [10]

Answer:

Expected rate of return =7.1% (Approx.)

Step-by-step explanation:

Given:

Current stock price = $50

Divided d = $2

Growth rate g = 5 %

Find:

Expected rate of return

Computation:

Expected rate of return = D(1+g)/Current Price + g

Expected rate of return = [2(1+5%)/50] + 5%

Expected rate of return =7.1% (Approx.)
