Mattie Evans drove 350 miles in the same amount of time that it took a turbopropeller plane to travel 1350 miles. The speed of the plane Has 200 mph faster than
the speed of the car. Find the speed of the plane.

(Simplify )

Answers

Answer 1

let

d1 = 250 mi the distance that Mattie Evans drove

v1 = the speed of Mattie Evans

d2 = 1300 mi the distance the plane traveled

v2 = the speed of the plane

The speed of the plane was 190 mph faster than the speed of the car:

v2 = v1 + 190

since time = distance/speed and they both traveled the same time we have

d1/v1 = d2/v2

250/v1 = 1300/v2 cross multiply

250v2 = 1300v1 divid eboth sides by 50

5v2 = 26v1

by solving the system of equations:

v2 = v1 + 190

5v2 = 26v1

we find

v1 = 45.24 mph

v2 = 235.24 mph

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x) = log(x), to achieve the graph of g(x) = log(-2x-4) + 1.

Answers

Using translation concepts, it is found that the parent function was:

Reflected over the x-axis.Horizontally compressed by a factor of 2.Shifted right 4 units.Shifted up 1 unit.

The parent function is:

[tex]f(x) = \log{x}[/tex]

The first transformation is:

[tex]\log{x} \rightarrow \log{-x}[/tex]

Which means that it was reflected over the x-axis.

Then, [tex]\log{-x} \rightarrow \log{-2x}[/tex], which means that it was horizontally compressed by a factor of 2.

Then, [tex]\log{-2x} \rightarrow \log{-2x - 4}[/tex], which means that it was shifted right 4 units.

Finally, 1 was added to the function, which means that it was shifted up 1 unit.

Does anyone get this question?

Answers

Answer:

a= 121°

b=62°

c=59°

Step-by-step explanation:

I first found b because they are vertical angles

Because I know the measure of angle b I take 180 (total sum of a triangle) and subtracted 62 from 180 which gave me 59 and because both base angles are equal to each other I divided 118 by 2 which gave me 59. Giving me the measure of angle c.

By adding angles b and c they would give me the measure of angle a.

An account earns 8.4% interest compounded monthly. If 12,000 is invested in the account initially, how much
interest is earned in this account over a 25 year period?

Answers

Answer:

$30,2400

Step-by-step explanation:

First, we need to find how much interest he earns in a month

8.4% of $12,000 = $1,008

Next, we multiply the amount of interest per month by the number of months in 25 years

25 years = 300 months

Now we can multiply the two values to get our final answer

1,008 x 300 = $30,2400

Molly O'Rourke assembles computers for Radius Computer. She works 8 hours per
day less 2 breaks at 15 minutes per break. She spends 45 minutes on each
computer. How many computers should she be able to assemble in one day?

Answers

Answer:

10

Step-by-step explanation:

I converted 8 hours to minutes so solve the equation easily

8 hours = 480 minutes

I subtracted the amount of time she takes for a break

480- (15+15) = 450

To find the number of computers she could repair I divided 450 by the number of minutes she spends repairing one computer.

[tex]\frac{450}{45}[/tex]= 10

Therefore, she could fix 10 computers during her 8 hours of work.

What is the equation of a horizontal ellipse with a major axis = 12 and a minor axis = 10?

Answers

The equation of the horizontal ellipse is [tex]\frac{x^2}{144}+\frac{y^2}{100}=1[/tex]

Ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.

The standard form of an ellipse with horizontal major axis is:

[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]

Where a > b

since a = 12, b = 10, hence:

[tex]\frac{x^2}{12^2}+\frac{y^2}{10^2}=1\\\\\frac{x^2}{144}+\frac{y^2}{100}=1[/tex]

Solve 2x^2-x>15

Show your work

Answers

Answer:

  x < -5/2  or  3 < x

Step-by-step explanation:

Subtracting 15 puts the relation into a more standard form:

  2x^2 -x -15 > 0

  (2x +5)(x -3) > 0 . . . . . factor

The zeros of these factors are x = -5/2 and x = 3.

For values of x between those values (-5/2 ≤ x ≤ 3), the product of these factors will be negative or zero. In order for the product to be positive, x must not be in that range.

The solution is ...

  x < -5/2  or  3 < x

_____

Additional comment

Several methods are taught for factoring a quadratic expression. One of my favorite is using a graphing calculator to find the zeros. If p is a zero, then (x-p) is a factor.

Another way to approach the factoring of ax^2 +bx +c is to find factor pairs of the product (ac) that have a total of b. Here, that means finding factors of 2(-15) = -30 that have a sum of -1. Consider ...

  -30 = (1)(-30) = 2(-15) = 3(-10) = 5(-6)

The sums of these pairs are -29, -13, -7, -1. With the values 5 and -6, you can rewrite the quadratic expression as 2x^2 +5x -6x -15. This can be factored by grouping pairs of terms:

  x(2x +5) -3(2x +5)

  (2x +5)(x -3) . . . . . . . the factorization we show above.

You can see on the graph that the quadratic is greater than 0 when x < -2.5 or x > 3.
