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

Answer:

x=2

Step-by-step explanation:

For there to be an undefined slope, there has to be no y-intercept. Therefore, the line looks vertical. So, the equation of a line with an undefined slope would be x=?. In this case, where we know a point (2,3), the equation would then be x=2.

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:

The second prize is worth $15325.632

Step-by-step explanation:

32580 + 68% = 54734.4 then 54734.4 minus 72% = 15325.632.

Are you sure that's the right question?

Answer:

70

Step-by-step explanation:

Since UT = VW, 5x + 5 = 4x + 20

x = 15

UV = 6x - 20 = 6(15) - 20 = 70

Answer:

9450

Step-by-step explanation:

3/4(12600)=X

12600*.75

9450

three fourths of last month's is three forths of 12600 therefore giving you the equation 3/4(12600)=x

Answer:

All of them

Step-by-step explanation:

Acute, right, scalene, equilateral, isosceles, and obtuse are ways to describe a triangle and classify it, especially with the type of angles it has. Acute can describe a 45-degree angle, just like right can describe a ninety-degree angle.

Answer:

B, D, and E

Step-by-step explanation:

Acute can never be right and Right cannot be equilateral

We are given with the function [tex]{\bf{f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}}[/tex] and we need to find [tex]{\bf \nabla f}[/tex] , that's nothing but just the gradient of f(x,y,z) . But before starting let's recall ;

For a function F(x, y, z, ....) , the gradient is given by ;

So , now let's calculate the partial derivatives of f(x, y, z) first with respect to x , y and z one after other .So consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.x will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial x}=e^{x+y}\cos (z)+(y+1)at\dfrac{1}{\sqrt{1-x^{2}}}}[/tex]

Simplifying will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial x}=\dfrac{e^{x+y}\cos (z)\sqrt{1-x^{2}}+(y+1)at}{\sqrt{1-x^{2}}}}[/tex]

Now again consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.y will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial y}=e^{x+y}\cos (z)+\sin^{-1}(x)at}[/tex]

Now , again consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.z will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial z}=-e^{x+y}\sin (z)}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\nabla f=\bigg\{\dfrac{e^{x+y}\cos (z)\sqrt{1-x^{2}}+(y+1)at}{\sqrt{1-x^{2}}}\bigg\}\hat{i}+\bigg\{e^{x+y}\cos (z)+\sin^{-1}(x)at\bigg\}\hat{j}-\bigg\{e^{x+y}\sin (z)\bigg\}\hat{k}}}}[/tex]

Answer:

4406/117

Step-by-step explanation:

Order of operations PEMDAS

Parentheses:

  [11 - 20 ÷ (52 - 13) ÷ 3 + 8] x 2

= [11 - 20 ÷ 39 ÷ 3 + 8] x 2

Multiply or divide:

⇒ [11 - 20 ÷ 39 ÷ 3 + 8] x 2

= [11 - 20/117 + 8] x 2

Parentheses:

⇒ [11 - 20/117 + 8] x 2

= 2203/117 x 2

Multiply or divide:

⇒ 2203/117 x 2

= 4406/117

Evaluating the expression using BODMAS:

                Work

Answer:

12 Assistants

Step-by-step explanation:

If 5 assistants can do same job as 3 specialists. You could say 1 specialist is equivalent to 5/3 Assistants.

So a job 8 specialists can complete in 9 hours. 8*5/3 Assistants can complete the same job in 9 hours.

40/3 Assistants - 9 hours - 1 job

X Assistants   -  10 hours - 1 job

Here if we give assistants more time, fewer assistants will be needed (inversely proportional). Here, the factor or ratio of increase in time from 9 to 10 is 10/9 or 9 * 10/9 = 10.

The number of assistants needed will be 40/3  divided by 10/9 which is

40/3 * 9/10 = 12.

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.

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]

Option C

Step-by-step explanation:

The total number of blocks y is three raised to the figure number x.

y = x³

Answer:

one solution

Step-by-step explanation:

3(x-2) =22 -x

Distribute

3x - 6 = 22-x

Add x to each side

3x+x-6 = 22-x+x

4x+6 = 22

Subtract 6 from each side

4x+6-6 = 22-6

4x= 16

Divide by 4

4x/4 = 16/4

x=4
