Answer:

3.2

Step-by-step explanation:

Your input: find the slope given two points P=(2,10) and Q=(−3,−6).

The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by

m=y2−y1/x2−x1

We have that x1=2, y1=10, x2=−3, y2=−6.

Plug the given values into the formula for slope: m=(−6)−(10)/(−3)−(2)=−16/−5=16/5.

Answer: the slope of the line is m=16/5≈3.2.

Let the length of hall in her plan = x cm

1 : 125 = x : 1050

[tex]\sf \dfrac{1}{125}=\dfrac{x}{1050}[/tex]

Cross multiply,

1*1050 = x*125

[tex]\sf x =\dfrac{1050}{125}[/tex]

x = 8.4 cm

The length of the hall in her plan = 8.4 cm

If the volume of this pyramid is 234 units, the height of the pyramid is equal to 13 units.

Mathematically, the volume of a pyramid is given by the formula:

[tex]Volume = \frac{1}{3} \times base\;area \times height[/tex]

For the base area:

The area of a right triangle is given by:

[tex]A=\frac{ab}{2} \\\\A=\frac{9 \times 12}{2} \\\\A=\frac{108}{2}[/tex]

A = 54 square units.

Given the following data:

Volume of a pyramid = 234 units.

Side lengths of right triangle = 9 and 12 units.

Now, we can calculate the height of the pyramid:

[tex]234 = \frac{1}{3} \times 54 \times height\\\\234=18h\\\\h=\frac{234}{18}[/tex]

h = 13 units.

In this case, 0 < a < 1.

True and false. Yes, we did modify the vertical stretch factor of the function to induce a type of vertical stretch. No, it is not a vertical stretch per se, but it is rather a vertical compression.

add numberator ( top number ); keep the denominator the same ( bottom number )

Line 1. (6/3)x or 2x = 13 (1/3) + (8/3)

------------------------------------------

Line 2. -13 (1/3) = (8/3)x - 2x

Hi there!

Part D:

We can use the Taylor Polynomial expansion for a second-degree polynomial:

[tex]P_3(x) = g(c) + \frac{g'(c)}{1!}(x - c) + \frac{g''(c)}{2!}(x - c)^2[/tex]
Where c is the value that the polynomial is centered about.

We are given that:
[tex]g(c) = 1\\\\g'(c) = 0\\\\g''(x) = 2[/tex]

Therefore:
[tex]P_3(x) = 1 + \frac{0}{1}(x - 2) + \frac{2}{2!}(x - 2)^2\\\\\boxed{P_3(x) = 1 + (x - 2)^2}[/tex]

Answer:

Step-by-step explanation:

Use FOIL method.

(x -2)(x+3) = x*x + x*3 + (-2)*x + (-2)*3

                 = x² + 3x - 2x -6  {Combinelike terms}

                  = x² + x - 6

(x² + x -6)*(2x + 1) = x²*2x + x²*1 + x*2x +x*1 + (-6)*2x + (-6)*1

                             = 2x³ + x² + 2x² + x -12x - 6

                             = 2x³ + 3x² - 11x - 6

Answer:

t=9

Step-by-step explanation:

Solve -

Distribute :7-(5t - 13) = - 25

7 - 5t + 13 = - 25

Add the numbers :7 – 57 + 13 = -25

20-51 = -25

Rearrange terms :20-51 = -25

-51+ 20 = -25

Subtract 20 from both sides :-51 + 20 = -25

-51+20-20-25-20

Simplify :Subtract the numbers

-51+ 20-20-25-20

-5:=-25-20

Subtract the numbers

-51 = -25-20

-51 = -45

-51 = -45

Divide both sides by the same factor : -51 = -45 -5t -5 -45- -5 =

Simplify : Cancel terms that are in both the numerator and denominator :: -5t - = -45 - -5

t = - 45 - -5

Divide the numbers :

t = - 45 - -5 ” t=9 ” here’s the answer

Answer:

[tex]f(x)=-5x^2+20x[/tex]

8.75 m

Step-by-step explanation:

Given ordered pairs:  (0, 0) (1, 16) (2, 20) (3, 15.5) (4, 0)

From inspection, we can see that the difference in the x-values is constant (they increase by 1 each time), yet the difference in the y-values is not constant.  Therefore, the relation is not linear.

As the y-values increase from 0 to 20 and then decrease back to 0, the curve is likely to be a parabola opening downwards.

The x-intercepts are at x = 0 and x = 4, so this suggests that the axis of symmetry is x = 2, and so the vertex is (2, 20).

Creating an equation using the x-intercepts:

[tex]f(x)=a(x-0)(x-4)[/tex]  where [tex]a[/tex] is some constant

[tex]\implies f(x)=ax(x-4)[/tex]

[tex]\implies f(x)=ax^2-4ax[/tex]

Creating an equation using the vertex form:

[tex]f(x)=a(x-2)^2+20[/tex]

[tex]\implies f(x)=ax^2-4ax+4a+20[/tex]

Equating constants to determine a:

[tex]4a+20=0 \implies a=-5[/tex]

Therefore, equation of best fit: [tex]f(x)=-5x^2+20x[/tex]

When x = 0.5:

[tex]\implies f(0.5)=-5(0.5)^2+20(0.5)[/tex]

                 [tex]=-1.25+10[/tex]

                 [tex]=8.75[/tex]

Therefore, an estimate for the height of the rocket 0.5 s after it's launched is 8.75 m

Answer:

d = 12.6 ft

Step-by-step explanation:

From inspection of the given diagram, the diameter of the circle is equal to the shortest leg of the right triangle.  

Pythagoras Theorem explains the relationship between the three sides of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the legs of a right triangle.

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

Therefore, use Pythagoras Theorem to find the measure of d.

Given values:

Substitute the given values into the formula and solve for d:

[tex]\implies d^2+18^2=22^2[/tex]

[tex]\implies d^2+324=484[/tex]

[tex]\implies d^2=484-324[/tex]

[tex]\implies d^2=160[/tex]

[tex]\implies d=\sqrt{160}[/tex]

[tex]\implies d=12.6491106...[/tex]

Therefore, d = 12.6 ft (nearest tenth).

Part a)

The home value is $120,000 and they get a loan for $90,000.

This must mean the down payment was 120,000 - 90,000 = 30,000 dollars. This is the payment made up front.

The mortgage has a monthly payment of $786.60 which is done for 25 years = 25*12 = 300 months. They pay back 786*300 = 235,800 dollars.

Therefore, the total amount they pay for the house is:

downPayment + loanRepayment = 30,000 + 235,800 = 265,800

=======================================================

Part b)

Refer to the previous part. Laura and Martin pay back $235,800 after being loaned $90,000

The total amount of interest is 235,800 - 90,000 = 145,800 dollars.

=======================================================

Part c)

The annual interest rate is 9.5% which converts to the decimal form 0.095

Divide this over 12 to get the monthly interest rate in decimal form.

0.095/12 = 0.00791667 approximately

Then multiply this with the initial balance of $90,000

90,000*0.00791667 = 712.5003

This rounds to 712.50 and this represents the interest for the first month.

This leads to:

principal = monthlyPayment  - interest

principal = 786.60 - 712.50

principal = 74.10

It is unfortunately common practice that the starting monthly payments will be mostly interest. As time goes on, the increase payments decrease because they are tied directly to the remaining balance.
