David’s family is driving from New York to Florida. They know the distance they will travel is about 1100 miles. If a map has a scale of 1 in. = 80 mi, about how far will the trip be on the map? StartFraction 8 over 110 EndFraction inches 11 inches 13 and three-fourths inches 88 inches.

Answers

Answer:

  13 and three-fourths inches

Step-by-step explanation:

The map distance can be found using a proportion with the map scale.

__

  map distance / (1100 mi) = (1 in) / (80 mi)

  map distance = (1100×1)/80 in = 13 3/4 in . . . multiply by 1100 mi; cancel mi

The trip will be about 13 3/4 inches on the map.

If the number of bacteria in a
colony doubles every 25 hours
and there is currently a population
of 10,000 bacteria, what will the
population be 75 hours Trom now?

Answers

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

10. Ryan inherited land from his grandfather. He decided to sell the land for $160,000, then place

the money in a new account that earns 1. 2% interest compounded bimonthly. How much

interest will he have earned after 30 years?

Answers

The amount of interest Ryan would earn at the end of 30 years given the interest rate is $69,250.27.

What is the interest rate on the new account?

When an account earns an interest that is compounded bimonthly, it means that it earns an interest every 2 months.

The formula that can be used to determine the interest earned is:

Future value - amount deposited

FV = P (1 + r)^nm

FV = Future value P = Present value R = interest rate = 1.2/6m = number of compoundingN = number of years

FV = 160,000(1.002^180) = $229,250.27

Interest = $229,250.27 -  $160,000 = $69,250.27

Without drawing the graph, find the coordinates of its intersection with the
x - and y -axes.
y = −2.4x +9.6
The intersection with the x − axis is the point with coordinates ( _,_ ).
The intersection with the y − axis is the point with coordinates(_,_)

Answers

Answer:

at X axis, Y=0 and at Y axis, X=0

accordingly substitute the value in the equation and find coordinates

Answer:

The intersection with the x-axis is the point with coordinates (4, 0)

The intersection with the y-axis is the point with coordinates (0, 9.6)

Step-by-step explanation:

The line intercepts (crosses) the x-axis when y = 0.

Therefore, substitute y = 0 into the equation and solve for x:

⇒ −2.4x + 9.6 = 0

⇒ −2.4x = -9.6

⇒ x = -9.6 ÷ −2.4

⇒ x = 4

So, the intersection with the x-axis is the point with coordinates (4, 0)

The line intercepts (crosses) the y-axis when x = 0.

Therefore, substitute x = 0 into the equation and solve for y:

⇒ y = −2.4(0) + 9.6

⇒ y = 9.6

So, the intersection with the y-axis is the point with coordinates (0, 9.6)

The tree diagram below shows all of the possible outcomes for flipping three coins.

A tree diagram has outcomes (H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T).

What is the probability that at least two of the coins will be tails?

Answers

Answer:

1/2

Step-by-step explanation:

Let H = the possible outcomes that include flipping heads

Let T = the possible outcomes that include flipping tails

In order to have an outcome of two coins having tails, that means for each outcome, you must have at least two T's.

Therefore, the possible outcomes are:

(H, T, T)

(T, H, T)

(T, T, H)

(T, T, T)

This is 4 possible outcomes, and since we want to find the probability we find the total number of outcomes and make a fraction.

[tex]4/8 = 1/2[/tex]

There are 8 outcomes, and since 4 work for this scenario, the answer is 1/2.

The amount that the credit union will finance is $24169.60

We have given that the cost of the car is $22,346. 16

and the credit union required 10% down payment

and sale tax=7.6%

The license and title charges are $125. 13.

We have to determine that the  amount that the credit union will

finance Now  we have sale tax 7.6% for $22,346. 16

Therefore, we get

[tex]\frac{7.6}{100} \times 22,346. 16=1698.31[/tex]

What is the amount that the credit union finance ?

credit union finance=cost of car+sales tax+the license and title  charges.

Find the inverse of the function, no solutions doesn't work and things like sqrt(9-x^2) doesn't either.

Answers

Answer:

The range of [tex]f(x)[/tex] is [tex]f(x)\in[0,3][/tex]

[tex]f^{-1}(x)=-\sqrt{-x^2+9}[/tex] with a domain [tex]x\in[0,3][/tex]

Step-by-step explanation:

Domain: set of input values (x-values)

Range: set of output values (y-values)

Given function:

[tex]f(x)=\sqrt{9-x^2}\quad(x\in[-3,0])[/tex]

Therefore, as the original function has a restricted domain, its range is also restricted:

[tex]f(-3)=\sqrt{9-(-3)^2}=0[/tex]

[tex]f(0)=\sqrt{9-0}=3[/tex]

[tex]\therefore\textsf{Range}\:f(x)\in[0,3][/tex]

To determine the inverse of a function

Change [tex]x[/tex] to [tex]y[/tex]:

[tex]\implies x=\sqrt{9-y^2}[/tex]

Square both sides:

[tex]\implies x^2=9-y^2[/tex]

Switch sides:

[tex]\implies 9-y^2=x^2[/tex]

Subtract 9 from both sides:

[tex]\implies -y^2=x^2-9[/tex]

Divide both sides by -1:

[tex]\implies y^2=-x^2+9[/tex]

Therefore:

[tex]\implies y=\sqrt{-x^2+9}\textsf{ and }y=-\sqrt{-x^2+9}[/tex]

As the range of the inverse function is the same as the domain of the original function:

[tex]\implies f^{-1}(x)=-\sqrt{-x^2+9}[/tex] only as the range is [-3, 0]

The domain of the inverse function is the same as the range of the original function.

[tex]\therefore\textsf{Domain of}\:f^{-1}(x):x \in [0,3][/tex]

The inverse of a function is ordinarily the reflection of the original function in the line [tex]y=x[/tex].

6 workers can build a wall in 30 days. If after 6 days 3 more workers join, find the number of days to build the same wall?

Answers

The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.

How to use inverse proportionality to determine building time of a wall

In this question we must use the definition of inverse proportionality, in which the number of workers ([tex]n[/tex]), no unit, is inversely proportional to the building time ([tex]t[/tex]), in days.

According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:

[tex]x = 24\,days \times \frac{6}{9}[/tex]

[tex]x = 16\,days[/tex]

In this scenario, the wall can be built in 22 days. [tex]\blacksquare[/tex]

Find all real $x$ that satisfy $$(2^x - 4)^3 (4^x - 2)^3 = (4^x 2^x - 6)^3. $$

Answers

The polynomial-like expression is satisfied by the real value x = 1.

How to determine the real solution of a polynomial-like expression

In this question we must apply the concepts of logarithms and algebra properties to solve the entire expression. Initially, we expand the right part of the expression:

[tex](2^{x}-4)^{3}+(4^{x}-2)^{3} = (4^{x}+2^{x}-6)^{3}[/tex]

[tex](2^{x}-4)^{3} + (4^{x}-2)^{3} = [(2^{x}-4)+(4^{x}-2)]^{3}[/tex]

[tex](2^{x}-4)^{3}+(4^{x}-2)^{3} = (2^{x}-4)^{3}+3\cdot (2^{x}-4)^{2}\cdot (4^{x}-2)+3\cdot (2^{x}-4)\cdot (4^{x}-2)^{2}+(4^{x}-2)^{3}[/tex]

[tex]3\cdot (2^{x}-4)^{2}\cdot (4^{x}-2)+3\cdot (2^{x}-4)\cdot (4^{x}-2)^{2} = 0[/tex]

[tex]2^{x}-4 + 4^{x}-2 = 0[/tex]

[tex]2^{x}\cdot 2^{x} + 2^{x}-6 = 0[/tex]

[tex]u^{2}+u - 6 = 0[/tex]

[tex](u+3)\cdot (u-2) = 0[/tex]

Hence, the roots of the pseudopolynomial are [tex]u_{1} = -3[/tex] and [tex]u_{2} = 2[/tex]. Only the second one have a real value of x. Hence, we have the following solution:

[tex]2^{x} = 2[/tex]

[tex]x\cdot \log 2 = \log 2[/tex]

[tex]x = 1[/tex]

The polynomial-like expression is satisfied by the real value x = 1. [tex]\blacksquare[/tex]
