9x10^2 which sentence matches the question assigned

Answers

Answer 1

The computation of the index shows that the value of 9 × 10² will be 900.

How to calculate the indices?

From the information given, we are told to calculate the value of 9 × 10². This will be calculated thus:

= 9 × 10²

Note that 10² simply means that you've to multiply 10 twice. This will be:

= 10 × 10 = 100

Therefore, 9 × 10² will be:

= 9 × 100

= 900

The swimmer comes back up 40 seconds after the timer was started.

Answers

The true statement about the equations include:

The swimmer dives to a depth of 14 feet.The swimmer comes back up 10 seconds after the timer was started.

How to solve the equation?

The equation given is h(t) = t² - 14t + 40. We'll factorize to get the value of t. This will be:

= t² - 14t + 40

= t² - 10t - 4t + 40

= t(t - 10) - 4(t - 10)

(t - 10) = 0.

t = 0 + 10

t = 10

In this case, the swimmer dives to a depth of 14 feet and then comes back up 10 seconds after the timer was started.

Arun took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4 plus $4.25 per mile. The total fare was $110.25, not including the tip. How many miles was the taxi ride?

Answers

Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.

So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.

So if you travel for m miles, the cost equation is:

C(m) = $4.10 + $0.50*m

Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:

$9.60 = C(m) = $4.10 + $0.50*m

$9.60 = $4.10 + $0.50*m

$9.60 - $4.10 = $0.50*m

$5.50 = $0.50*m

$5.50/$0.50 = m = 11

This means that Arun traveled 11 miles in the taxi.

The Eva traveled 25 miles in the taxi.

It is required to find how many miles was the taxi ride.

What is arithmetic?

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

The taxi company charged a pick-up fee of $4 plus $4.25 per mile.

The total fare was $110.25.

The cost equation is:

C(m) = $4 + $4.25*m

Now, we know that for Eva the total fare (total cost) was $110.25, then we need to solve:

$110.25 = C(m) = $4 + $4.25*m

$110.25-$4=$4.25*m

$106.25=$4.25*m

m =25

Therefore, the Eva traveled 25 miles in the taxi.

apothem of 5 inches.


Area = [?]in2

Answers

Answer:

  80 in²

Step-by-step explanation:

When side length and apothem of a regular polygon are given, the applicable area formula is ...

  A = 1/2Pa

where P is the perimeter of the polygon, and 'a' is its apothem.

__

The perimeter of a regular 8-sided polygon will be 8 times the side length, so the area is ...

Gabrielle needs to rent a car while on vacation. The rental company charges $19.95, plus 15 cents for each mile driven. If Gabrielle only has $40 to spend on the car rental, what is the maximum number of miles she can drive?

Round your answer down to the nearest mile.

Answers

Answer:

  133 miles

Step-by-step explanation:

The limited budget gives rise to an inequality that can be solved for the maximum number of miles.

__

setup

The rental cost for m miles will be the sum of the fixed charges and the product of the mileage charge and the number of miles.

  cost = 19.95 +0.15m

We want this to be no greater than 40, so we have the inequality ...

  40 ≥ 19.95 +0.15m

solution

This two-step inequality can be solved in the usual way:

  20.05 ≥ 0.15m . . . . . step 1, subtract 19.95 from both sides

  133.667 ≥ m . . . . . . . step 2, divide by the coefficient of the variable

The maximum whole number of miles Gabrielle can drive is 133.

packs of hot dogs and how many packs of buns do you need to purchase in order to
have the exact same number of each?

Answers

Using the least common multiple, it is found that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.

How to find the number of packs needed?

First, we need to find the total number of each element, finding the least common multiple of the sizes of each package, that is, 8 and 12.

The lcm is found factoring them by prime factors, hence:

8 - 12|2

4 - 6|2

2 - 3|2

1 - 3|3

1 - 1

Hence, lcm(8,12) = 2³ x 3 = 24.

Then:

24/8 = 3.24/12 = 2.

Which means that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.

Consider the graph of f(x) = (x + 5)2 – 3. Rewrite the equation by making one change in the equation of f(x) so that the graph has no x-intercepts.

Answers

Using the discriminant of a quadratic equation, if the graph is translated shifted up 4 units, the graph will have no x-intercepts.

What is the discriminant of a quadratic equation and how does it influence the solutions?

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are as follows:

If [tex]\mathbf{\Delta > 0}[/tex], and it has 2 x-intercepts.If [tex]\mathbf{\Delta = 0}[/tex], it has 1 x-intercept.If [tex]\mathbf{\Delta < 0}[/tex], it has no x-intercepts.

In this problem, the function is given by:

f(x) = (x + 5)² - 3.

In standard form:

f(x) = x² + 10x + 22.

We want to find coefficient k for which the function has [tex]\Delta < 0[/tex], then:

f(x) = x² + 10x + 22 + k.

The coefficients are a = 1, b = 10, c = 22 + k, hence:

[tex]\Delta < 0[/tex]

10² - 4(22 + k) < 0

100 - 88 - 4k < 0

4k > 12

k > 3.

Hence, with k = 4, the function is shifted up 4 units, and the graph will have no x-intercepts.

The best intervals would be 41-45, 46-50, 51-55, 56-60, 61-65, and 69-70.

The best way to decide the appropriate interval would be to find the range of the numbers.

What is the smallest value in the data?

The minimum is the smallest value in the data set. The maximum is the largest value in the data set.

What is the largest minus the smallest?

This would be 69-42=27.

If you need six intervals you would need to round 27 up to 30 to be able to divide it out evenly and include all of the data.

The best intervals would be 41-45, 46-50, 51-55, 56-60, 61-65, and 69-70.

This way you are one over and one under the highest and lowest values.
