Answer: A

Step-by-step explanation:

Power rule: derivative of x^(something) is (something)* x (something -1). Rewrite the second term as x^(-7) and it all becomes -3x^(-3-1) + (-7)x^(-7-1). Rest is just writing it in a "nicer" form

The total length of wire needed to fasten 175 bundles is 2,975 cm.
UkoKoshka [18]

According to the conversion table we know,

1 meter = 100cm

This means if we need to convert meters to centimeters, we need to multiply by 100

Or

If we need to convert from centimeters to meters, we need to divide by 100.

Here the length of the wire needed to wrap 175 bundles = 2975 cm.

Now as we need to convert it to meters.

We need to divide this by 100.

We get

2975/100= 29.75

So 2975 cm = 29.75 m

Option D) is the right answer

Just answer number 7 and 8
melamori03 [73]
We are given the equation:
F = 2.25+0.2(m-1)
where:
F is the fare
m is the number of miles.

In question 7, we are given that the fare (F) is equal to $6.05 and we need to get the number of miles. To do so, we will simply substitute with the fare in the given equation and solve for the number of miles (m) as follows:
F = 2.25 + 0.2(m-1)
6.05 = 2.25 + 0.2(m-1)
6.05-2.25 = 0.2(m-1)
3.8 = 0.2(m-1)
3.8/0.2 = m-1
19 = m-1
m = 19+1
m = 20 miles

Number 8 is exactly the same, but we will substitute F=7.65 and again solve for m

A washer and a dryer cost $995 combined. The washer cost $45 more than the dryer. What is the cost of the dryer?​
Talja [164]

When a washer and a dryer cost $995 combined. If  the washer cost $45 more than the dryer, then the cost of the dryer is $475

The combined cost of a washer and a dryer = $995

Consider the cost of a dryer as x

The washer cost $45 more than the dryer.

The cost of the washer = x+45

Then the equation will be

x+x+45 = 995

2x+45 = 995

2x = 950

x = 950/2

x = 475

The cost of the dryer is $475

Hence, when a washer and a dryer cost $995 combined. If  the washer cost $45 more than the dryer, then the cost of the dryer is $475
