Some people advise that in very cold weather, you should keep the gas tank in your car more than
half full. Lou's car had 5.1 gallons in the 12-gallon tank on the coldest day of the year. Lou filled the
tank with gas that cost $3.90 per gallon. How much did Lou spend on gas?
Answer:
The least amount he could spend to get his car above half full would be $3.90
Explanation:
Half of 12 is 6 therefore 6.1 is above half.
6.1 minus 5.1 is 1.
If gas is $3.90 per gallon then,
3.90
* 1
is 3.90

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]
Use the substitution method to solve the system of equations.
5x+2y=1
Y=-x+2
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

Roslyn is an engineer. She is designing a part for a new engine. The length of the part is 16 centimeters (cm), the width is 6 cm, and the height of the cone top is 5 cm, as shown.
[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-The length of the part is 16 centimeters The part of new engine is composed of 1 cone, 1 cylinder and 1 hemisphere The width of the engine is 6 cmThe height of the cone is 5 cmTo Find :-We have to find the total volume of the part Let's Begin :-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,
The height of the cone is 5 cmThe diameter of the cone is 6 cmTherefore, Radius of the cone = 3 cmSubsitute 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 .
For second part Second part is composed of cylinderWe know that,
The volume of cylinder
[tex]\bold{ = {\pi}r^{2}h }[/tex]
Here,
The diameter of the cylinder is 6 cmSo, Radius = 3 cmThe length of the cylinder = 16 - (Length of cone + Length of hemisphere) Length = 16 - 11 = 5 cmSubsitute 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
For third partThird part is composed of hemisphereWe know that,
Volume of hemisphere
[tex]\bold{=}{\bold{\dfrac{ 2}{3}}}{\sf{ {\pi}r}}[/tex]
Here,
The diameter of the hemisphere is 6 cmSo, Radius = 3cmSubsitute 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
Therefore,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 .

write a point slope equation for the line that goes through the point (2,-3) and has slope 4
Step-by-step explanation:
As per given Information
Slope m = 4
That line goes through the point (2,-3)
Using Point Slope Form
y - y₁ = m ( x - x₁)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 .
If the equation y=5(1.7)^x is plotted on a semi-log scale graph, then the linearized equation will be log(y)=mx+b, where m=_____?_____ and b=____?_____.
Answer:
m=1.7 and b=5
Step-by-step explanation:
5= the y intercept
1.7= the slope that's why it has x as its exponent. Because in mx+b the slope is the one that keeps being multiplied.

Age of car = 6 years.
Original cost = $12,995.
The current market value is $
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.
How can the current value of the car be calculated?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

Here is a set of signed numbers: 7, -3, 1/2, -.8, .8, 1/10, -2
1) If their numbers represent temperatures in degrees Celsius, which is the coldest?
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
