Sven investigates the amount of damage to the head gaskets on the trucks in his fleet and find that the damage index depends on the ambient temperature. He develops the equation y = - 2 3 x + 14 to model the relationship. What does 14 mean? A) The temperature only adds 14 to the damage index. B) If there is no damage index then the ambient temperature is 14. C) If the damage index is 0, then the ambient temperature would be 0. D) If the ambient temperature is 0 then the damage index would be 14.

Answers

Answer 1

Given is the damage index equation, [tex] y=\frac{-2}{3} x+14 [/tex]

where y represents damage index, and x represents ambient temperature.

It is similar to slope-intercept form of linear equation given by y = mx + b.

Where m is said to be the slope of line and b is the y-intercept of the line. When x = 0, y = b.

Similarly, if plug x = 0 in the damage index equation, [tex] y=\frac{-2}{3} (0)+14=14 [/tex]

So, If ambient temperature, x = 0. Then damage index, y = 14.

Hence, option D is correct i.e. " If the ambient temperature is 0 then the damage index would be 14".

Answer 2

Answer:

The answer is D because 14 is the y-intercepts, which means that the x-value is 0. So the correct meaning is If the ambient temperature is 0 then the damage index would be 14. .

Answers

37% hope this helps .............

Since the bag contains 15 green, 18 yellow, and 16 orange balls, the total number of balls in the bag are 15+18+16=49.

Therefore, the probability of the event that the drawn ball is yellow is given by:

P(yellow)=[tex] \frac{Number of Yellow Balls}{Total Number of Balls} [/tex]

[tex] \therefore P(Yellow)=\frac{18}{49}\times 100\approx36.73\approx37 [/tex]%

Thus, the the probability of the event, to the nearest percent, that the drawn ball is yellow is 37%.

how many liters of a 60% acid solution must be mixed with a 75% acid solution to obtain 20L of a 72% solution

Answers

x = amount of the 60% solution

y = amount of the 75% solution

now, how much is 60% of x?  well, (60/100) * x, or 0.6x.

and how much is 75% of y?  well, (75/100) * y, or 0.75y.

well, the resulting mixture is 72% of acid and then water or other liquids, but we know is that much off 20 liters, how much is that then?  well 72% of 20 is (72/100) * 20, or 14.4.

regardless of what "x" and "y" are, we know that the resulting substance has to be 20 liters, thus x + y = 20.

and we also know that the amount of acid in each amount, will add up to the acid in the resulting amount.

since we know that there is 0.6x liters of only acid and 0.75y liters of only acid in each, thus 0.6x + 0.75y = 14.4.

[tex]\bf \begin{array}{lccc} &\stackrel{liters}{amount}&\stackrel{\%~of~acid}{amount}&\stackrel{acid~liters}{quantity}\\ &------&------&------\\ \textit{60\% solution}&x&0.60&0.6x\\ \textit{75\% solution}&y&0.75&0.75y\\ ------&------&------&------\\ mixture&20&0.72&14.4 \end{array} \\\\\\ \begin{cases} x+y=20\implies \boxed{y}=20-x\\ 0.6x+0.75y=14.4\\ -------------\\ 0.6x+0.75\left( \boxed{20-x} \right)=14.4 \end{cases} \\\\\\ 0.6x-0.75x+15=14.4\implies -0.15x=-0.6 \\\\\\ x=\cfrac{-0.6}{-0.15}\implies x=4[/tex]

C. x (plus sign over minus sign) square root of 41.
D. x (plus sign over minus sign) square root of 73.

Please help! This is timed!

Answers

Solve for x over the real numbers by completing the square:
(x - 12) (x + 4) = 9

Expand out terms of the left-hand side:
x^2 - 8 x - 48 = 9

Add 48 to both sides:
x^2 - 8 x = 57

Add 16 to both sides:
x^2 - 8 x + 16 = 73


Write the left hand side as a square:
(x - 4)^2 = 73

Take the square root of both sides:
x - 4 = sqrt(73) or x - 4 = -sqrt(73)

Add 4 to both sides:
x = 4 + sqrt(73) or x - 4 = -sqrt(73)

A four-sided polygon has sides that measure (2x + 1), (4x – 10), (x + 1)and (12x + 25). What is the perimeter of the polygon, in terms of x?

Answers

The perimeter would be found by adding all 4 of these expressions together, remembering that we can combine like terms.  Here is what it would look like:
(2x+1)+(4x-10)+(x+1)+(12x+25).  The bold parts are terms that can be combined together and all the other numbers (constants) can be combined.

2x+4x+1x+12x=19x
1+ (-10)+1+25 = 17
19x+17 would be the simplified expression that represents the perimeter.

Final answer:

The perimeter of the polygon, given the sides (2x + 1), (4x – 10), (x + 1), and (12x + 25), is calculated by summing these expressions to get 19x + 17.

Explanation:

To find the perimeter of a four-sided polygon, we add together the lengths of all the sides. Given the sides (2x + 1), (4x – 10), (x + 1), and (12x + 25), the perimeter P in terms of x is calculated by summing these expressions:

P = (2x + 1) + (4x – 10) + (x + 1) + (12x + 25)

Now, we combine like terms:

P = 2x + 4x + x + 12x + 1 – 10 + 1 + 25

P = (2x + 4x + x + 12x) + (1 – 10 + 1 + 25)

P = 19x + 17

Therefore, the perimeter of the polygon in terms of x is 19x + 17.

Leticia charges $8 per hour to babysit. She babysat Friday night for 4 hours, and then she babysat again on Saturday. She earned a total of $72. How many hours did Leticia babysit on Saturday? Choose two answers: one for the equation that models this situation and one for the correct answer.

Answers

She babysat five hours on Saturday. 75 divided by 8 is 9, 9 minus 4 is five.

First, we have to look at the equation that models this situation. We learn that the price per hour of babysitting is $8. On Friday, Leticia babysat for 4 hours, and on Saturday, she babysat an unknown amount of time. In total, she earned $72. Therefore:

8 ( 4 + x ) = 72

( 4 + x ) = 72 / 8

4 + x = 9

x = 9 - 4

x = 5

Leticia babysat 5 hours on Saturday.

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the square is or .

the volume of the prism or (4r2)(h) or r2h.

Answers

"For every cross section, the ratio of the area of the circle to the area of the square is or ."

To find this ratio we need to find areas of the circle and the square.
Circle:
[tex]Area= radius^{2} * \pi \\ A_{1} = r^{2} * \pi [/tex]
Square:
[tex]Area= side^{2} \\ A_{2} = (2r)^{2} \\ A_{2} 4r^{2}= [/tex]
Now we divide these two areas to find ratio:
[tex]ratio= \frac{ A_{1} }{ A_{2} } \\ ratio= \frac{r^{2} * \pi }{4r^{2}} \\ ratio= \frac{ \pi }{4} [/tex]

"Since the area of the circle is the area of the square,"
From the ratio above we can see that areas are not same.

"

Formula for volumes of cylinder and prism follow the formula:
[tex]Volume=base*height[/tex]
For cylinder:
[tex]V=r^{2} * \pi *h[/tex]
For prism:

What is the ratio of two quantities?

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

For this case, we're specified that:

Radius of the circle of the cross section of the cylinder = r unitsSide length of the square cross section of the square prism = 2r units

Then, the area of the circle is:

[tex]\pi r^2 \: \rm unit^2[/tex]

and the area of the square is: [tex]\rm side^2 = (2r)^2= 4r^2 \: \rm unit^2[/tex]

The ratio of the area of the circle to the area of the square is:

[tex]\dfrac{\pi r^2}{4r^2} = \dfrac{\pi}{4} = \pi : 4[/tex]

Thus, the ratio of the area of the cross sectional circle and area of the cross sectional square is π : 4

Parabola form narrowest and widest.

Larger value of a most narrowest graph.

Smaller value of a most widest graph.

[tex]y=2x^2,\ \ \ a=2[/tex]

[tex]y=-x^2,\ \ \ a=-1[/tex]

[tex]y=\dfrac{1}{8}x^2,\ \ \ a=\dfrac{1}{8}[/tex]

Now, we arrange the value of a in descending order.

[tex]2>1>\dfrac{1}{6}>\dfrac{1}{8}[/tex]

2 is largest value of these.

The circumference of a circle is 18.84 kilometers. What is the circle's radius? C=18.84 km Use 3.14 for ​. kilometers

Answers

The circle's radius is 3. That is because the formula for the circumference of a circle is 2(pi)r. Divide 18.84 by 2 then divide that by (pi). Hope this helps!

The Circle's radius is roughly 3 kilometers.

To find the compass of a circle when given the circumference, we can use the formula

C = 2πr

where C is the circumference, and r is the compass.

Given that the circumference is18.84 kilometers, we can substitute these values into the formula and break for the compass

18.84 = 2 x3.14 x r

Dividing both sides of the equation by 2 x 3.14

18.84  /( 2 x 3.14) = r

Simplifying the right side

r ≈18.84/6.28

r ≈ 3 kilometers.

Thus, the circle's radius is roughly 3 kilometers.
