Top triangle: if the know angle measures are 90 and 55 and there are a total of 180, 90 + 55 + a = 180. This means that angle a = 35°

Bottom triangle: if a is 35, the angle connected to it is 35 because they are vertical angles. The angles of this triangle are 35 + 120 + b = 180. Angle b = 25°

What is the quotient of d − 2 √ d 4 − 5 d 3 + d + 17
Tcecarenko [31]

Answer: d^3 - 3d^2-5

Step-by-step explanation:

For finding the quotient of the given division,

In the long division method, we will follow the following steps.

Step 1 : Here the divisor is d-2 and dividend is d^4-5 d^3 + d + 17

Multiply (d-2) by d^3  and subtract the dividend by the resultant.

We get -3d^3+d

Step 2: Multiply (d-2) by -3d^2  and subtract the remaining dividend by the resultant.

We get  -5d^2+17

Step 3 : Multiply (d-2) by -5  and subtract the remaining dividend by the resultant.

We get  7

Since, after getting 7 it is not possible further division,

Hence, Remainder = 7,

Quotient = sum of all expression by that we multiply (d-2) = d^3 - 3d^2-5

Answer:

Local minimum at x = 0.

Step-by-step explanation:

Local minimums occur when g'(x) = 0 and g"(x) > 0.

Local maximums occur when g'(x) = 0 and g"(x) < 0.

Set g'(x) equal to 0 and solve:

0 = 2x (x − 1)² (x + 1)²

x = 0, 1, or -1

Evaluate g"(x) at each point:

g"(0) = 2

g"(1) = 0

g"(-1) = 0

There is a local minimum at x = 0.

Thirty adults were asked which of the following conveniences they would find most difficult to do without: television, refrigera
Brut [27]

Answer:

(D) Pie chart

Step-by-step explanation:

The most appropriate method to represent the resulting data is the pie chart. This is because, in this sample, the variables are few and of nominal type.

Of the rest of the options, the only other that could be used is the histogram, since it can represent nominal variables with their corresponding frequency. The rest of the options have other uses not appropriate for this type of sample.

A washer and dryer cost $600 combined. The cost of the washer is three times the cost of the dryer
Sveta_85 [38]
First, assign two variables to the prices of the two appliances.
'w' will represent the price of a washer, and 'd' will represent the price of a dryer.

Because "the washer is three times the cost of the dryer," we can form this equation:
w = 3d
On top of that, we know the washer and dryer add up to 600, making another equation.
w + d = 600

Because we know the value of 'w,' we can input that into the equation 'w + d = 600'
(3d) + d = 600
Simplify:
4d = 600
d = 150

Since the washer is three times the price of the dryer:
w = 3(150) = 450

The dryer costs $150, and the washer costs $450.
