Answer:

It will cover 4.5 miles in 30 seconds.

Step-by-step explanation:

An airplane is flying from nyc to la.

The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation :

d=0.15t ...(1)

Let us assume we need to find the distance at t = 30 s.

Put t = 30 s in equation (1).

d=0.15 × 30

d = 4.5 miles

Hence, it will cover 4.5 miles in 30 seconds.

Step-by-step explanation:

Given as :

The time period for the car loan = t = 2 years

The rate of interest applied = r = 6% at simple interest

The interest amount = S.I = $264

Let The principal amount which Elsa borrowed = $p

Now, From simple interest method

Simple Interest = 

Or, S.I = 

Or, $264 = 

Or, $264 × 100 = 12 × p

Or,  p = 

∴ p = $2200

So, The principal she borrowed = p = $2200

Hence,The Principal amount that Elsa borrowed for the car loan is $2200 . Answer

Mathematically;

1 foot = 12 inches

3 feet = 36 inches

2 feet = 24 inches

So 36 to 2 and 24 to 1 1/3

That will be ratio 36/2 = 18 to 1

same as 25 divided by 1 1/3 = 18 to 1

Answer:

2 zeros

Step-by-step explanation:

Here, we want to identify the number of zeros for the function

The number of zeros a particular function has is dependent on the degree of the function

This particular function is quadratic and has a degree of two

So what this means is that it is expected that the function has two zeros

The number fourths in the given fraction is 7.

The given fraction is 7/4.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The number fourths (1/4) in 7/4 are 7

Which is 7×(1/4)

Therefore, the number fourths in the given fraction is 7.

Answer:

Step-by-step explanation:

Given the recursive formula

Finding the 2nd term:

Answer:

12.6

Step-by-step explanation:

Given the recursive formula

f(n) = 0.4 × f(n − 1) + 11

and first term is f(1) = 4

Finding the 2nd term:

f(2) = 0.4×f(1) + 11

f(2) = 0.4×4 + 11 = 1.6 + 11 = 12.6

Answer:

6:15 x = 15

Step-by-step explanation:

Simplify the ratio 8:20 by 4.

Get 2:5

SImplify 6:x by 3

GEt 2:x

To get them to be the same multiply 3 times 5. 5 from the ratio and 3 from what you divide.

Anwser 2.5=2.5

X=15

The value of x for the equivalent ratios 8/20 = 6/x is 15.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

8:20 is equivalent to 6:x

This means,

8/20 = 6/x

Solve for x.

8/20 = 6/x

x = (6 x 20)/8

x = 3 x 5

x = 15

Thus,

The value of x is 15.

Answer:

D.$79.89

Step-by-step explanation:

Cost of one yard of fabric = $6.99

Length of fabric bought = 8 yards

Cost of one bag of polyester filling = $7.99

Number of bags of polyester filling bought = 3

Total cost of fabric = [tex]6.99\times 8=\$55.92[/tex]

Total cost of polyester filling = [tex]7.99\times 3=\$23.97[/tex]

Total cost of materials bought = Total cost of fabric + Total cost of polyester filling

[tex]=55.92+23.97=\$79.89[/tex]

Total cost of materials bought is [tex]\$79.89[/tex].

Answer:

[tex]\dfrac{1 - 6 \ln y}{2}[/tex]

Step-by-step explanation:

[tex] \ln \dfrac{\sqrt{e}}{y^3} = [/tex]

[tex] = \ln \dfrac{e^\frac{1}{2}}{y^3} [/tex]

[tex] = \ln e^\frac{1}{2} - \ln y^3 [/tex]

[tex]= \dfrac{1}{2} \ln e - 3 \ln y[/tex]

[tex]= \dfrac{1}{2} - 3 \ln y[/tex]

[tex]= \dfrac{1 - 6 \ln y}{2}[/tex]

The given logarithmic expression can be written as [tex]\frac{1-6ln\ y}{2}[/tex]

Given that,

Based on the above information, the calculation is as follows:

[tex]= ln \frac{\sqrt{e} }{y^3}\\\\= ln \frac{e^{1/2}}{y^3} \\\\= ln \e^{1/2} - lny3\\\\= \frac{1}{2}ln e - 3 ln y\\\\= \frac{1}{2} - 3 ln \ y \\\\= \frac{1- 6ln \y}{2}[/tex]

Therefore we can conclude that the given logarithmic expression can be written as [tex]\frac{1-6ln\ y}{2}[/tex]
