Answer:

2.5 inches

Step-by-step explanation:

If Jeff has a big scoop of ice cream that is 10 inches tall and it melts by 25% in a minute, the height of the ice cream after one minute is 2.5 inches.

You have to find what 25% of 10 inches is.

25% of 10 inches = 2.5 inches

Therefore, the height of the ice cream after one minute is 2.5 inches.

Answer: 7.5 inches tall

Step-by-step explanation: if 25% of the ice cream melted, it means 75% is remaining, therefore you say 75÷100 =0.75 then you multiply it by 10 inches to get 7.5 inches.

Answer:

A(x+2)(x-3)(x+6) where A is a constant.

If you want to change the order in that multiplication you can.

Read answer for my options on what your answer could look like.

Let me know the choices or if you have any questions.

Step-by-step explanation:

It says which like you have choices...

But I can give you several polynomials with those zeros.

By factor theorem if you have -6 is a zero then x+6 is a factor.

By factor theorem if you have -2 is a zero then x+2 is a factor.

By factor theorem if you have  3 is a zero then x-3 is a factor.

So a polynomial with those factors I mentioned is:

(x+6)(x+2)(x-3)

or

4(x+6)(x+2)(x-3)

or

-12(x+6)(x+2)(x-3)

or

1.4(x+6)(x+2)(x-3)

and so on....

I guess you could also say

4(x+6)(x+2)(x-3)^3.

It didn't say it had to have this multiplicity of 1.

Anyways I think you are probably looking for an option that says something like this:

A(x+6)(x+2)(x-3)

where A is a constant.

Keep in mind multiplication is commutative so it could be written as

A(x+2)(x-3)(x+6) or something similar to that.

Answer:

False.

Step-by-step explanation:

The function f(x) =2x is not an logarithmic function. Rather, it is a linear function. The reason for this is that in f(x) = 2x, there is no log or ln involved on the right hand side of the equation. It is the polynomial of the first degree, which means it is a straight line function. It is important to note that for any value of x, the value of the function changes with the same proportion. This is because the derivative of the function is a constant, which means that the rate of change is constant. The graph of the function will be a line passing from the origin and (1,2) and will have the positive slope. Therefore, f(x) is not a logarithmic function, which means that the statement is false!!!

Answer:

[tex]m=\dfrac{5}{2}[/tex]

Step-by-step explanation:

If the equation of the line is

[tex]y=mx+b,[/tex]

then m represents the slope of the line and b represents the y-intercept of the line. This equation is called the equation of the line in the slope form.

Rewrite the equation of the line in the slope form

[tex]y-4=\dfrac{5}{2}(x-2)\\ \\y-4=\dfrac{5}{2}x-\dfrac{5}{2}\cdot 2\\ \\y-4=\dfrac{5}{2}x-5\\ \\y=\dfrac{5}{2}x-1[/tex]

Thus, the slope of the line is

[tex]m=\dfrac{5}{2}[/tex]

The slope of a line whose equation is [tex]y-4 = \frac{5}{2}(x-2)[/tex] is [tex]\frac{5}{2}[/tex]

In this case;

The equation in question is;

[tex]y-4 = \frac{5}{2}(x-2)[/tex]

Combining like terms;

[tex]y= \frac{5}{2}x-5+4[/tex]

The equation of the line is

[tex]y= \frac{5}{2}x-1[/tex]

From the equation the slope of the line is [tex]\frac{5}{2}[/tex], while

The y-intercept is -1

Answer:

<4,22>.

Step-by-step explanation:

This question involves the concepts of addition and scalar multiplication of vectors. It is given that the vector u = <-4, 1> and v = <-1, 6>. To find -2u, simply multiply -2 with the elements of u. This will give:

-2u = <-4*-2, 1*-2> = <8, -2>.

Similarly:

4v = <-1*4, 6*4> = <-4, 24>.

Hence,

-2u + 4v = <8, -2> + <-4, 24> = <8-4, -2+24> = <4,22>.

So the correct answer is <4,22>!!!

To find -2u + 4v, we will perform vector addition after scaling vectors u and v by -2 and 4, respectively.
First, we scale the vector u by -2. To do this, we multiply each component of vector u by -2:
u = <-4, 1>
-2u = -2 * <-4, 1> = <(-2)*(-4), (-2)*1> = <8, -2>
Now, we scale the vector v by 4. To do this, we multiply each component of vector v by 4:
v = <-1, 6>
4v = 4 * <-1, 6> = <4*(-1), 4*6> = <-4, 24>
Now that we have -2u and 4v, we can add these two vectors together. We do this by adding the corresponding components:
-2u + 4v = <8, -2> + <-4, 24>
Adding the x-components:
8 + (-4) = 4
Adding they-components:
-2 + 24 = 22
Hence, the resultant vector of -2u + 4v is:
-2u + 4v = <4, 22>
So the solution to -2u + 4v is the vector <4, 22>.

Answer:

The x-intercepts are (5,0) and (7,0)

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(6,-5)

substitute

[tex]y=a(x-6)^{2}-5[/tex]

Find the coefficient a

with the y-intercept (0,175) substitute the value of x and the value of y in the equation

For x=0, y=175

[tex]175=a(0-6)^{2}-5[/tex]

[tex]175=36a-5[/tex]

[tex]36a=180[/tex]

[tex]a=5[/tex]

substitute

[tex]y=5(x-6)^{2}-5[/tex]

Find the x-intercepts

Remember that the x-intercepts are the values of x when the value of y is equal to zero

For y=0

[tex]0=5(x-6)^{2}-5[/tex]

[tex]5(x-6)^{2}=5[/tex]

simplify

[tex](x-6)^{2}=1[/tex]

square root both sides

[tex]x-6=(+/-)1[/tex]

[tex]x=6(+/-)1[/tex]

[tex]x=6(+)1=7[/tex]

[tex]x=6(-)1=5[/tex]

therefore

The x-intercepts are (5,0) and (7,0)

Answer:

The correct answer for question A is x=2i or x= -2i

The correct answer for question B is (x+2i)(x-2i)

Step-by-step explanation:

Solution of question A:

x²+4=0

Subtract 4 from both sides.

x²+4-4=0-4

x²=-4

Take square root of both sides

√x²=+/-√-4

We know that i=√-1

So,

x=+/-(√4)(√-1)

x=+/-2i

Therefore x= 2i, x= -2i

Solution of question B:

x²+4

It cannot be factored using real number coefficient. You have to use complex numbers.

As we know -4 =(2i)², so we can write as:

x²+4=x² - (-4)= x²-(2i)²

Now factor using the difference of squares:

x²+4=(x+2i) (x-2i)....

Answer:

The correct answer is option 1)  (6,7)

Step-by-step explanation:

Points to remember

Mid point formula

Let (x₁, y₁) and (x₂, y₂) be the end points of a line segment, then the coordinates of the midpoint of the line segment is given by

[(x₁ + x₂)/2, (y₁ + y₂)/2]

To find the coordinates of B

Let A(x₁, y₁) =  (-4, 3), and M(1, 5)

Coordinates of B be (x₂, y₂)

We have,

[(x₁ + x₂)/2, (y₁ + y₂)/2] = (1, 5)

(x₁ + x₂)/2 = 1

(-4 + x₂)/2 = 1

-4 + x₂ = 2

x₂ = 2 + 4 = 6

(y₁ + y₂)/2 = 5

(3 + y₂)/2 = 5

3+ y₂ = 10

y₂ = 10 - 3 = 7

Therefore coordinates of B(6,7)

The correct answer is option 1)  (6,7)

Final answer:

The coordinates of point B, which lies diametrically opposite to A on circle M with a known center at (1, 5), are determined to be (6, 7).

Explanation:

Since segment AB is the diameter of circle M, and we know the coordinates of A (-4, 3) and center M (1, 5), we can find B by using the fact that the center of the circle is the midpoint of the diameter. The midpoint formula states that the midpoint M can be found using the following formulas:

Mx = (Ax + Bx) / 2

My = (Ay + By) / 2

Therefore, to find Bx and By, we can rearrange the formula:

Bx = 2Mx - Ax

By = 2My - Ay

Solving this gives us B as:

Bx = 2(1) - (-4) = 6

By = 2(5) - 3 = 7

So the coordinates of point B are (6, 7).

Answer:

Option C is correct.

Step-by-step explanation:

-10<3x-4<8

Solving the given equation,

we know that if a<b<c then a<b and b<c

s0, -10<3x-4 and 3x-4<8

Solving to find the value of x

-10<3x-4

Switching sides,

3x-4>-10

3x > -10 +4

3x > -6

x > -6/3

x > -2

3x-4 < 8

3x < 8+4

3x < 12

x < 12/3

x < 4

s0, x >-2 and x < 4

-2 < x <4

Option C is correct.

-10 < 3x-4 < 8

Isolate x

First add 4 to each side:

-6 < 3x < 12

Divide each side by 3:

-2 < x < 4

The inequality signs do not contain equal to, so you would have open circles on both -2 and positive 4.

This means x is greater than -2 and less than 4, which is shown as the 3rd choice.

Answer:

I is at -7

Step-by-step explanation:

Step 1 : Find the distance between point F and G.

Point G is at 2

Point F is at 8

The distance between them is of 6 points/numbers.

Step 2 : Find I

Point H is -1

Point I will be 6 points/numbers behind point H so you have to count backwards.

Going 6 points/numbers backwards will bring you to -7 which is point I.

Therefore, I is -7.

Final answer:

To make a 4 percent ethanol mixture, 4000 gallons of 6 percent ethanol gasoline must be added to 2000 gallons of gasoline with no ethanol.

Explanation:

To determine how many gallons of gasoline containing 6 percent ethanol must be added to 2,000 gallons of gasoline with no ethanol to achieve a mixture that is 4 percent ethanol, we can use a simple algebraic equation.

Let x be the number of gallons of 6 percent ethanol gasoline we need to add. The total amount of ethanol in the new mixture will be 0.06x gallons since 6 percent of the x gallons is ethanol. We need the mixture to have 4 percent ethanol overall, so we can set up the equation: 0.06x / (2000 + x) = 0.04. We're calculating the proportion of ethanol in the total mixture, which includes the initial 2000 gallons plus the x gallons we're adding.

Multiplying both sides of the equation by (2000 + x) to eliminate the fraction gives us 0.06x = 0.04(2000 + x), which simplifies to 0.06x = 80 + 0.04x. Subtracting 0.04x from both sides gives us 0.02x = 80, and dividing both sides by 0.02 gives us x = 80 / 0.02. This simplifies to x = 4000.

Thus, 4000 gallons of 6 percent ethanol gasoline must be added to the 2000 gallons of non-ethanol gasoline to achieve a 4 percent ethanol mixture.

Answer:

[tex]x=-\frac{6}{7}[/tex]

[tex]y=-17\frac{6}{7}[/tex]

Step-by-step explanation:

We are given the following system of equations that we are to solve:

[tex] y = 8 x - 1 1 [/tex] - (1)

[tex] y = x - 1 7 [/tex] - (2)

Since the left hand side of both the equations is the same so we will equate the right hand sides of both the equations to get:

[tex]8x-11=x-17[/tex]

[tex]8x-x=-17+11[/tex]

[tex]7x=-6[/tex]

[tex]x=-\frac{6}{7}[/tex]

Substituting this value of [tex]x[/tex] in (1) to find [tex]y[/tex]:

[tex]y=8(-\frac{6}{7})-11[/tex]

[tex]y=-17\frac{6}{7}[/tex]

Final answer:

The solution to the system of equations y = 8x - 11 and y = x - 17 is found by setting the equations equal to each other and solving for x, then substituting back to find y. The solution is x = -6/7 and y = -125/7.

Explanation:

To solve the system of equations, you want to find a single value for x and y that satisfies both equations simultaneously. The given equations are:

y = 8x - 11

y = x - 17

Since both equations are equal to y, we can set them equal to each other and solve for x:

8x - 11 = x - 17

Now, let's get all the x terms on one side and the numbers on the other:

8x - x = -17 + 11

7x = -6

Dividing both sides by 7 gives us:

x = -6/7

Now that we have x, we can substitute it back into one of the equations to find y:

y = 8(-6/7) - 11

y = -48/7 - 11

Convert -11 to a fraction,

y = -48/7 - 77/7

y = -125/7

The solution to the system of equations is x = -6/7 and y = -125/7.
