Answer:

D:86

Step-by-step explanation:

all three triangle sides always equal 180, so first you find the missing side. As you can see the angle you are finding is complementary to the missing side so its just the 180 minus the first answer.

Solve the following system of equations. (Hint: Use the quadratic formula.) f(x) = 2x² 3x g(x)=-3x² + 20 (0.-10) and (1, 17) (-2
jasenka [17]

The solution of the system of equation is the intersection point of the two quadratic equations, so we need to equate both equations, that is,

2x^2-3x-10=-3x^2+20

So, by moving the term -3x^3+20 to the left hand side, we have

5x^2-3x-30=0

Then, in order to solve this equation, we can apply the quadratic formula

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

In our case, a=5, b=-3 and c=-30. So we get

x=\frac{3\pm\sqrt{(-3)^2-4(5)(-30)}}{2(5)}

which gives

\begin{gathered} x=2.76779 \\ and \\ x=-2.16779 \end{gathered}

By substituting these points into one of the functions, we have

f(2.76779)=-2.982

and

f(-2.16779)=5.902

Then, by rounding these numbers to the nearest tenth, we have the following points:

\begin{gathered} (2.8,-3.0) \\ and \\ (-2.2,5.9) \end{gathered}

Therefore, the answer is the last option

Answer:

$16,666.67

Step-by-step explanation:

PMT= PV*i Where PMT is the withdrawals ,PV is present value and i is the dicounting rate

PMT = $1,000.00

PV= ?

i = 6%

hence  $1,000 = PV*6%

PV=1,000/6%

PV = 16,666.67

Sara has a stack of 8 plates each plate is 0.5 inches and she is trying to wrap them as a gift the largest plate has a diameter
levacccp [35]

Answer: No her plates will not fit in the box

Step-by-step explanation: Each plate is 0.5 inches tall; therefore, the stack of 8 plates will have a height of .

Also, the diameter of the largest plate is 10 inches or has a radius of 5 inches, which matches the radius of the cylindrical box; therefore, we know that the stack of plates can fit into the base area of the cylindrical box.

What we want to figure out now is the height of the cylindrical box to see if it is greater than or equal to 4 inches—the height of the stack of plates.

The volume of a cylinder is , and since for our cylindrical box the volume is 150 cubic inches; therefore,

putting in  and solving for height  we get

,

which is not greater than 4 inches, which means the plates will not fit into the box since the height of the stack is greater than the height of the box.
