Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.

Answers

Answer:

Josie is correct.

Step-by-step explanation:

There are other ways of finding the value of the function at x = 1.

For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.

a farmer makes a profit of x cents on each of the (x+5) eggs her hen lays. if her total profit was 84 cents find the number of eggs the hen lays

Answers

Given: A farmer makes a profit of x cents on each of the (x + 5) eggs her  hen lays.

To find: The number of eggs  the hen lays.

Solution:

Now we have given that farmer makes a profit of x cents on each of the (x + 5) eggs her  hen lays.

That means the farmer has x + 5 eggs, which also means that each egg can make a profit of x percent.

Then the equation formed will be:

               x × ( x + 5 ) = 84

                x^2 + 5x - 84 = 0

               (x - 7) (x + 12) = 0

               x = 7 , -12

The positive solution will be considered, so the answer is 7+5 = 12 eggs

Answer:

               The number of eggs  the hen lays is 12.

Put the quadratic equation y=4x^2-24x+5 into vertex form by completing the square then state the coordinates of the vertex.

Answers

Answer:

(3, -31)

Step-by-step explanation:

Factor 4 out of the first two terms:

y=4x^2-24x+5 becomes y=4(x^2 - 6x) +5

Next, complete the square of (x^2 - 6x):  It is x^2 - 6x + 9 - 9

Insert this into y=4(x^2 - 6x) +5 in place of x^2 - 6x:

y=4(x^2 - 6x) +5 => y=4(x^2 - 6x + 9 - 9) +5, or

                                y=4( (x - 3)^2 - 9 ) + 5, or

                                y = 4(x - 3)^2 - 36 + 5, or:

                                 y = 4(x - 3)^2 - 31

Compare this to:       y = a(x - h)^2 + k

We see that the coordinates of the vertex (h, k) are (3, -31), and that a = 4.

x 2 +2x+y 2 =0 what is the center and radius of the circle?

Answers

Center = (-1,0)   Radius= 1

when you complete the square your equation should look something like

(x²+2x+1) (y²+0) = 1.The 1 on the left side coming from (b/2)² which is (2/2)² which equals 1 and whatever you add to one side, you have to add to the other so when you add 0+1 you get the 1 on the right side. Then factor or use the (b/2) from earlier without the ² so you should get (x²+1) + (y²+0) = 1. Flip the sign so you have negative 1 and 0. For the radius, square the right side and of course, [tex]\sqrt{1}[/tex] is simply 1 so your radius is 1. A lot of 1's huh? lol at least it makes the operations nice and simple :)

"select all the numbers that are solutions to the equation x^3=27"

Answers

Answer:

x=3

Step-by-step explanation:

So lets try and solve this to find an answer. To do this, lets just think about what makes 27. 3x3x3? Yup. Well wait, whats 3^3? Oh, thats 3x3x3. So this means, x must be 3.

Can x be -3 as well? No, this is because the exponent is odd, and any negative number will still be negative unless the exponent is even.

So in this equation, 3 is the only answer.

What is the equation for a line with a slope of
4/5 and a y-intercept of (0,7)?

Answers

Y = mx + b
m = slope, b = y intercept
Plug in the values
Solution: y = 4/5x + 7

Answer:

y = 4/5x + 7

Step-by-step explanation:

Use the slope intercept form, y = mx + b, where m is the slope and b is the y intercept

Plug in the slope and y intercept value of 7 to create the equation

y = mx + b

y = 4/5x + 7

So, the equation of the line is y = 4/5x + 7

Home Depot is delivering washing machines to buyers. The washing machines are rectangular prisms that measure 5 ft x 5 ft x 6 ft. These machines are then packed into a delivery truck with dimensions of 30 ft x 15 ft x 12½ ft.

What is the volume of the delivery truck? please show work

How many washing machines can be packed into the delivery truck? show work please

Answers

Answer:

37.5

Step-by-step explanation:

Volume of the washing machine = 5 ft x 5 ft x 6 ft

= 150 ft³

Volume of the delivery truck = 30 ft x 15 ft x 12½ ft

= 5,625 ft³

How many washing machines can be packed into the delivery truck?

Number of washing machine in the truck = Volume of the delivery truck / Volume of the washing machine

= 5,625 ft³ / 150 ft³

= 37 1/2

Or

= 37.5

Answer:

1/48

Step-by-step explanation:

For the left spinner, there are 8 equal slots and one of which is 6. The probabililty of landing on just six would be 1/8.

For the right spinner, there are 6 equal slots and one of which is C. The probability of landing on just C would be 1/6.

Now when we try to get to spin both of them at the same time we need to multiply the probabilities of both:

1/8*1/6=1/48

Hope this helps!

Answer:

Step-by-step explanation:

the probability is 1/48 because

to get a number 6 is a 1/8 percent chance.

the get the letter C is a 1/6 percent chance

you multiply 1/6 and 1/8 to get the probability of 1/48
