The true statement about the equations include:

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

We are asked to factor out the GCF in the expression

[tex]\star~\star\mathrm{6x^3+3x}~\star~\star[/tex]

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

So let's divide.

But first. we should work out the GCF.

Both terms have 3x in common, so we divide both terms by 3x:

[tex]\mathrm{6x^3+3x}[/tex]

[tex]\mathrm{3x(2x^2+1)}[/tex]

To ensure that we've factored correctly, we can always use the distributive property, distribute 3x and see whether or not we end up with [tex]\mathtt{6x^3+3x}[/tex].

So the answer is

[tex]\mathrm{3x(2x^2+1)}[/tex]

Notice I put parentheses around 2x²+1. This indicates that 3x is multiplied times both 2x² and 1.

Hope it helps you out! :D

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

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:

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.

We have given a data set,

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

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.

Answer:

Step-by-step explanation:

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

__

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

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

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.

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

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.

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
