Answer:

-3 would probably be the coldest

Step-by-step explanation:

based on my research the higher the number in celsius the hotter it is. the lower the number the colder it is. and since -8 is the lowest it is the coldest temperature.

also may i ask what you dont understand? i can help you

edit

so the choices are

7 , -3 , 1/2 , -0.8 , 0.8 , 1/10 , - 2

we can ignore the choices without the negative signs so..

-3, -0.8, and - 2

is what we have left

-0.8 would not be the coldest because it is not the lowest value

-2 would not be the coldest because it is not the lowest value

-3 is the coldest because it is the lowest value.

You may think that -3 should be the highest since it has "3", but in negative its different. -1 would be greater than -5 because it is closer to 0

Answer:

X = -1

Step-by-step explanation:

Rewrite equations:

y = -x + 2; 5x + 2y = 1

Step: Solve y = -x + 2y = 1 for y:

y = -x + 2

Step: Substitute -x + 2 for y in 5x +2y =1 :

5x +2y = 1

5x +2 (-x+2) =1

3x + 4 =1 (simplifiy both sides of the equation)

3x + 4 + - 4 = 1 + -4

(Add -4 to both sides)

3x = -3

3x/3 = -3/3 (Divide both sides by 3)

x = -1

Answer: I believe the (-1,3) is the answer!  (hope this helps!)

Answer:

[tex]\int\limits^{10}_{10} {f(x)} \, dx=0[/tex]

Step-by-step explanation:

Question

If [tex]\int\limits^3_2 {f(x)} \, dx=5[/tex] and [tex]\int\limits^{10}_3 {f(x)} \, dx=12[/tex], then what is the value of [tex]\int\limits^{10}_{10} {f(x)} \, dx[/tex]?

Answer and Explanation

Assuming you typed your question right, since the upper and lower bounds are the same, then there's no area underneath the curve of f(x), so [tex]\int\limits^{10}_{10} {f(x)} \, dx=0[/tex]

Answer:

502.4 yd^2 for the first one

Step-by-step explanation:

For the first one, because the formula to find the lateral surface value is L.S.A = 2πrh, we can then plug in the values to get this:

2(3.14)(2)(40) = 502.4 yd ^2

do u need step by step or do u just need the answer cuz the answer is 4(3y-2)

[tex]\bold{\huge{\underline{ Solution }}}[/tex]

Let divide the part of engine into three parts as it is composed of 3 different figures.

We know that,

Volume of cone

[tex]\bold{=}{\bold{\dfrac{ 1}{3}}}{\bold{{\pi}r^{2}h}}[/tex]

Here, we have,

Subsitute the required values,

Volume of the first part that is cone

[tex]\sf{=}{\sf{\dfrac{ 1}{3}}}{\sf{ {\times}3.14{\times}(3)^{2}{\times}5}}[/tex]

[tex]\sf{=}{\sf{\dfrac{ 1}{3}}}{\sf{ {\times}3.14{\times}9{\times}5}}[/tex]

[tex]\sf{ = 3.14 {\times} 3 {\times} 5 }[/tex]

[tex]\sf{ = 3.14 {\times} 15 }[/tex]

[tex]\sf{ = 3.14 {\times} 15 }[/tex]

[tex]\bold{ = 47.1 cm^{3} }[/tex]

Thus, The volume of cone is 47.1 cm³ .

We know that,

The volume of cylinder

[tex]\bold{ = {\pi}r^{2}h }[/tex]

Here,

Subsitute the required values in the above formula,

Volume of the second part that is cylinder

[tex]\sf{ = 3.14{\times} (3)^{2}{\times} 5}[/tex]

[tex]\sf{ = 3.14{\times} 9 {\times} 5}[/tex]

[tex]\sf{ = 3.14{\times} 45 }[/tex]

[tex]\bold{ = 141.3 cm^{3}}[/tex]

Thus, The volume of the cylinder is 141.3 cm³

We know that,

Volume of hemisphere

[tex]\bold{=}{\bold{\dfrac{ 2}{3}}}{\sf{ {\pi}r}}[/tex]

Here,

Subsitute the required values,

Volume of third part that is hemisphere

[tex]\sf{=}{\sf{\dfrac{ 2}{3}}}{\sf{{\times} 3.14 {\times}3}}[/tex]

[tex]\sf{ = 2 {\times} 3.14 }[/tex]

[tex]\bold{ = 6.28 cm^{3} }[/tex]

Thus, The volume of the hemisphere is 6.28 cm³

The total volume of the part

= Volume of cone + Volume of cylinder + Volume of hemisphere

[tex]\sf{ = 47.1 + 141.3 + 6.28 }[/tex]

[tex]\sf{ = 188.4 + 6.28 }[/tex]

[tex]\sf{ = 194.68 cm^{3} }[/tex]

[tex]\bold{ = 194.7 cm^{3} }[/tex]

Hence, The total volume of the part is 194.7 cm³ .

The original value of the car of $12,995, and 10% value and 6% repair

cost, give the actual current market value of the car as; $1,234.525.

The market value of the car is found as follows;

The age of the car = 6 years

Original market value of the car = $12,995

The percentage of the market value after 6 years = 10%

The percentage of the value used for repairs ≈ 5%

Current market value = Book value - Cost of repair

Book value = $12,995 × 0.1 = $1,299.5

Cost of repair = $12,995 × 0.1 × 0.05 = $64.975

Current market, value = $1,299.5 - $64.975 = $1,234.525

Answer:

Multiplique 329 * 684 = 225036

Step-by-step explanation:

As per given Information

Slope m = 4

That line goes through the point (2,-3)

Using Point Slope Form

where,

y₁ = -3

x₁ = 2

from the given information

On putting the value we obtain

↝ y-(-3) = 4 ( x - 2)

↝ y + 3 = 4x - 8

↝ y = 4x -8 - 3

↝ y = 4x - 11

So, the point slope equation for that line is y = 4x-11 .
