Answer:

The value of car decreases by 12% each year.

Step-by-step explanation:

A car dealership creates an expression to model the value of a new car t years after it is purchased and the expression is [tex]P(0.88)^{t}[/tex] ..... (1)

Now, if the value of the car depreciates at a rate of r% each year, then the value of the car (Say, P) will be depreciated to the value

[tex]P' = P(1 - \frac{r}{100} )^{t}[/tex] ...... (2)

Now, comparing the expressions in (1) and (2), we get

[tex]1 - \frac{r}{100} = 0.88[/tex]

⇒ [tex]\frac{r}{100} = 0.12[/tex]

⇒ r = 12%.

Therefore, the value of the car decreases by 12% each year. (Answer)

Answer:

6ab + b^2 - 17a - 4b + 10

Step-by-step explanation:

-2(a+b-5)+3(-5a+2b)+b(6a+b-8)

Now we break the parenthesis. To break that, we multiply each of the value inside the parenthesis by the adjacent number. That is, for the first part of the expression, we multiply by -2, then by 3, and then by b.

Algebraic Operations need to be considered:

[ (-) x (-) = (+); (-) x (+) = (-)]

= [-(2*a) + (-2*b) - (-2*5)] + [3*(-5a) + (3*2b)] + [(b*6a) + (b*b) - (b*8)]

= -2a - 2b +10 -15a + 6b + 6ab + b^2 - 8b

Now, we will make the adjustment by the similarity value.

= - 2a - 15a - 2b + 6b - 8b + 6ab + b^2 + 10

= - 17a - 4b + 6ab + b^2 + 10

= 6ab + b^2 - 17a - 4b + 10

Therefore, the answer of the expression is = 6ab + b^2 - 17a - 4b + 10

We can classify each number as:

0 = ones place

8 = tenths place

7 = hundredths place

3 = thousandths place

Now that we know that 7 is in the hundredths place we can write this as: 7/100 (0.07)

In mathematics, a ratio is the comparison of two numbers or quantities which is an amount, measurement, or number.

For example, a ratio can be used to compare the number of shaded rectangles to the number of unshaded rectangles. In the first image, I provided an image of what this ratio would look like.

A proportion is a pair of ratios that are equal to each other.

If we're asked to determine if two ratios can form a proportion, we really want to see if the ratios are equal to each other. It's important to understand that if two ratios are equal, they form a proportion.

Answer:

The function has a y-intercept of (0,-1).

Step-by-step explanation:

The given function is f(x) = x - 1 .......... (1)

Now, we have to choose from the statements given in options that best describe the function.

I think option 3 is the only statement that describes the function well.

Option 3 states that the function has a y-intercept of (0,-1).

If we put x = 0 in the function then will get y = - 1.

So, the function (1) has y-intercept at (0,-1). (Answer)

Final answer:

Only statement 3 is correct, which states that the function  (x) = x - 1 has a y-intercept of (0, -1). The function's x-intercept is actually (1, 0), the slope is consistently -1, and the other statements are either incorrect or irrelevant.

Explanation:

We are asked to determine which expressions best describe the function  (x) = x - 1.

Therefore, only statement 3 correctly describes the function  (x) = x - 1.

Answer:

[tex]- 5 \log 2 = - \log 32[/tex]

Step-by-step explanation:

We have to convert an exponential equation into the logarithmic equation.

The given equation is  

[tex]2^{-5} = \frac{1}{32}[/tex]

Now, taking log on both sides we get,  

[tex]\log 2^{-5} = \log\frac{1}{32}[/tex]

⇒ [tex]- 5 \log 2 = \log 1 - \log 32[/tex]

{Since we know from the logarithmic property that [tex]\log a^{b} = b \log a[/tex] and [tex]\log \frac{a}{b} = \log a - \log b[/tex] }

⇒ [tex]- 5 \log 2 = - \log 32[/tex] {Since [tex]\log 1 = 0[/tex] }

Hence, this is the required logarithmic equation. (Answer)

The linear equation created from the points (3,3) and (1,-5) is y = 4x - 9, found by first calculating the slope, then finding the y-intercept.

To create a linear equation from two points, you need to find the slope and y-intercept. Let's use the two points given: (3,3) and (1,-5). The slope (m) is found using the formula [tex](y2 - y1) / (x2 - x1),[/tex] so [tex]m = (-5 - 3) / (1 - 3) = -8 / -2 = 4[/tex]. Next, use the y = mx + b formula to find the y-intercept (b). Substituting one of the points and the slope, we get: [tex]3 = 4 * 3 + b[/tex], solving for b, gives b = -9. So, the linear equation is [tex]y = 4x - 9.[/tex]

Answer:

-7x+y=36

Step-by-step explanation:

y-1=7(x+5)

y-1=7x+35

y=7x+35+1

y=7x+36

36=y-7x

36=-7x+y

-7x+y=36

The equation y - 1 = 7(x + 5) is transformed into the standard form by distributing, rearranging terms, and manipulating to ensure a positive coefficient for x, resulting in 7x - y = -36.

To write the equation y - 1 = 7(x + 5) in standard form, we first distribute the 7 to both terms within the parentheses which results in y - 1 = 7x + 35. Then, to ensure both variables are on one side of the equation and the constant is on the other, as required by the standard form, we subtract 7x from both sides. This gives us -7x + y = 36. Normally, standard form is written with the coefficient of x being positive, so to achieve this, we multiply the entire equation by -1, resulting in 7x - y = -36. So, the equation y - 1 = 7(x + 5) in standard form is 7x - y = -36.

Answer:

x-intercept is 2, y-intercept is 10.

Step-by-step explanation:

y=-5x+10

y=mx+b

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

m=-5 which means that the slope of this equation is -5.

And to find the y-intercept,

plug in x=0 into the equation and find out the value of y.

y=-5(0)+10=0+10=10

So the y-intercept is 10.

And to find the x-intercept,

plug in y=0 into the equation and find out the value of x.

0=-5x+10

-5x=0-10

-5x=-10

5x=10

x=10/5=2

So the x-intercept is 2.

It looks like you are good up to problem 4 so I will start there. I believe this is practice worksheet featuring the pyth. theorem. The pyth. theorem is used to find the length of sides in a right triangle notable the hypotenuse (side opposite of 90 degree angle).

4. The monitor is a rectangle but that does not stop you from constructing a right triangle. The smaller lengths are 16 in and 12 in respectively. The hypotenuse of the triangle is the diagonal of the rectangle. To find the length use the pyth. theorem.

diagonal^2 = 16^2+12^2

diagonal = 20 in

7. You know the speeds of both trains and the time spend traveling. You know they are traveling at a 90 degree angle so you can use pyth. theorem. But wait... you need to find the distances traveled for both trains. You can find that though because speed x time = distance.

50mph x 3hrs = 150mi

40mph x 3hrs = 120mi

The distance between the trains after 3 hours is the hypotenuse which can be determined by pyth. theorem.

distance^2 = 150^2+120^2

distance = 192 mi approx.

8. First find length of one piece of wiring. Use pyth theorem. Actually 3,4,5 pyth. triplet in which 5 is the hypotenuse. So you have 5 ft for the length of one piece of wiring. How many pieces of wiring do you need? Well, each tree needs 3 pieces and there are 6 trees so you need 18 pieces.

18 x 5 = 90 ft of wiring

From the work I see, you have a great understanding of the pyth. theorem. Keep it up!

Answer: OPTION B.

Step-by-step explanation:

The missing figure is attached.

For this exercise you need to use the Pythagorean Theorem. This is:

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

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.

Then you can say that:

[tex]a=PR\\b=PS=17\\c=RS=33[/tex]

Therefore, knowing these values, you can substitute them into [tex]a^2=b^2+c^2[/tex]:

[tex]PR^2=17^2+33^2[/tex]

Finally you must solve for PR in order to find its value. This is:

[tex]PR=\sqrt{17^2+33^2}\\\\PR=37.12[/tex]

The measure of a side is the length it possess. The measure of PR for the given rectangle is given by: Option B: 37.12 units.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

For the given case, we can use the fact that opposite side of a rectangle are of same length, and one more fact that all the adjacent side pairs of a rectangle are perpendicular to each other(means the minor angle between them is of 90 degrees).

The question is missing the figure, which is attached below.

Since PQRS is a rectangle, thus, we have:

|PS| = |QR| = 17 units

|PQ| = |RS| = 33 units

Thus, for the triangle PSR, as angle S internally is of 90 degrees, we can use Pythagoras theorem.

From Pythagoras theorem for PSR, where PR is hypotenuse, we get:

[tex]|PR|^2 = |PS|^2 + |SR|^2\\\\|PR| = \sqrt{17^2 + 33^2} = \sqrt{1378} \approx 37.12[/tex] units.

(positive root was taken as length is a non-negative quantity).

Thus, the measure of PR for the given rectangle is given by: Option B: 37.12 units.

Explanation:

The question asks how many miles Keegan rides the bus in 5 days if he travels 4 miles to school and 4 miles home each day. To solve this, we can multiply the daily round trip distance by the number of school days in a week. Keegan travels 8 miles per day (4 miles to school and 4 miles back home). So, in 5 days, Keegan will have traveled:

8 miles/day  imes 5 days = 40 miles
