Answer:

The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.

Step-by-step explanation:

The volume of a cylinder having base area 'A' and height 'H' is given by  V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by [tex]V' = \frac{1}{3} A(3H) = AH[/tex].

So, V = V'

Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)

Answer:

θ = ±π/3 + 2kπ

θ = 0 + 2kπ

Step-by-step explanation:

2 sin² θ + 3 cos θ = 3

Use Pythagorean identity:

2 (1 − cos² θ) + 3 cos θ = 3

2 − 2 cos² θ + 3 cos θ = 3

0 = 2 cos² θ − 3 cos θ + 1

Factor:

0 = (2 cos θ − 1) (cos θ − 1)

cos θ = 1/2

θ = ±π/3 + 2kπ

cos θ = 1

θ = 0 + 2kπ

Answer:

The standard from of the expression is: [tex](x +1)^2 + (y-1)^2  = (2)^2[/tex]

Step-by-step explanation:

Here the given expression is :

[tex]x^2+2x+y^2-2y=2[/tex]

Now, the standard form of a circle is given as :

[tex](x-h)^2 + (y -k)^2  = r^2[/tex]

Here, (h,k)  = Coordinates of Center,   r = Radius

Also, use the algebraic identity:

[tex](a \pm b)^2 = a^2 + b^2 \pm 2ab\\[/tex]

Now, converting the given expression in the standard form, we get:

[tex]x^2+2x+y^2-2y=2[/tex]

Add 2 on both sides of the equation, we get:

[tex]x^2+2x+y^2-2y  +2=2  + 2\\\implies x^2+2x + 1 +  y^2-2y + 1  = 4\\\implies  (x^2+2x + 1 )+  (y^2-2y + 1)  = 4\\\implies (x +1)^2 + (y-1)^2  = (2)^2[/tex]

So, here the standard from of the expression is:

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

Center coordinates here are  (h,k)  = ( -1 ,1) and Radius  = 2 units

Step-by-step explanation:

For a number to be the solution of the equation, the number should satisfy it.

To check if t satisfies, plug the number and compare LHS and RHS.

1) 3z + 4 = 15

Substituting z = -5, we get 3(-5) + 4 = -15 + 4 = -11 [tex]$ \ne $[/tex] 15.

Therefore, -5 is not the solution of the equation.

2) 8 - [tex]$ \frac{x}{2} $[/tex] = 0

Substituting x = 16, we get 8 - [tex]$ \frac{16}{2} = 8$[/tex]

⇒ 8 - 8 = 0

Therefore, 16 is a solution of the equation.

3) 4(p + 5) = 60

Substitute p = 12. 4(12 + 5) = 4(17) [tex]$ \ne $[/tex] 60.

Not a solution.

4) 8 - k = -48

If k = -40, then 8 - (-40) = 48

On the RHS we have -48. Not equal. So, it is not a solution.

Do 25% of $55 which is $13.75

You have the right idea but you're supposed to then subtract $13.75 from the original

So:

55 - 13.75 = $41.25

Answer:

53

Step-by-step explanation:

Given: The sum of two digit number is 8

           Reversing the digit will get us number 18 less than the original.

Lets take x as tenth digit of our number and y as unit digit of our number.

As given sum of digit is 8

∴ [tex]x+y= 8[/tex]

∴ [tex]y= 8-x[/tex] -       equation 1

We also know that reversing the digit will get us number 18 less than the original.

∴ [tex]10y+x = 10x +y-18[/tex]

Now, lets put the value of y from equation 1

⇒ [tex]10(8-x) + x = 10x+ (8-x)- 18[/tex]

⇒ [tex]80-9x= 9x-10[/tex]

⇒ [tex]90= 18x[/tex]

∴ [tex]x= 5[/tex]

Next, substituting the value of x in equation 1

[tex]y= 8-x[/tex]

⇒ [tex]y= 8-5 = 3[/tex]

∴ [tex]y= 3[/tex]

∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.

Abigail has eaten 3/8 of a pound of candy.

This is the answer because 3/4 is equivalent to 6/8, and if Abigail has eaten 3/8 of a pound of that 6/8 pound of candy, then there will be 3/8 remaining (6/8 - 3/8 = 3/8).

To find out how much candy Abigail has eaten, we subtract the amount of candy she has left (3/8 of a pound) from the original amount she bought (3/4 of a pound). The calculation shows that Abigail has eaten 3/8 of a pound of candy.

The student is asking how much candy Abigail has eaten if she originally bought 3/4 of a pound and now has 3/8 of a pound left. To calculate the amount of candy eaten, we subtract the amount left from the original amount. Since we are working with fractions, we ensure the denominators are the same before subtracting.

The steps to solve the problem are as follows:

Original amount of candy: 3/4 pound

Amount left: 3/8 pound

Calculate how much has been eaten: (3/4) - (3/8)

Convert the first fraction to have a denominator of 8: (6/8) - (3/8)

Subtract the second fraction from the first: (6/8) - (3/8) = 3/8

Abigail has eaten 3/8 of a pound of candy.

Answer:

1849 handles

Step-by-step explanation:

Break Even is the point when costs = profit

Since each handle takes $0.20 to make (cost) and they sell it for ($4.20), the profit from each handle is:

Profit = 4.20 - 0.20 = $4

The weekly costs are $7396. Break even would mean to gain this amount from selling handles (profit).

So, from each handle, we get $4 and to make $7396, we would need:

7396/4 = 1849 handles

We require 2 equations with the repeating part after the decimal point.

let x = 0.77.... (1) ← multiply both sides by 10

10x = 7.77.... (2)

Subtract (1) from (2) thus eliminating the repeating decimal

9x = 7 ( divide both sides by 9 )

x = [tex]\frac{7}{9}[/tex]

Answer:for every five red beeds their are 5 black beeds

Step-by-step explanation:

To maintain the relationship of black beads to red beads, we need to know the ratio of black beads to red beads in the existing bracelet or the desired ratio. If the ratio is 1:1, for example, then you would need to use an equal number of black and red beads.

However, based on the information provided, it's not clear what the current or desired ratio is. If Jamie wants to maintain a specific ratio, you need to know that ratio.

For example, if the ratio is 2:1 (2 black beads for every 1 red bead), and you want to use 5 red beads, you would need 5×2=10 black beads to maintain the 2:1 ratio.

Without more information on the desired or existing ratio, it's not possible to determine whether using 5 red beads alone would maintain the relationship of black beads to red beads.

complete step by step

To maintain the relationship of black beads to red beads in a bracelet, we need to understand the existing ratio and then apply it to the new situation.

Let's say the current ratio of black beads to red beads in Jamie's bracelet is 3:2. This means that for every 3 black beads, there are 2 red beads.

Now, Jamie wants to make a bracelet with 5 red beads. To maintain the same ratio, we need to determine the corresponding number of black beads.

The ratio of black beads to red beads is 3:2, which simplifies3x:2x for some positive value of x.

Since Jamie wants 5 red beads, we set up the equation: 2x-5

Now, solve for x:

x- 5/2

Now that we know the value of  x, we can find the number of black beads:

Number of black beads - 3x-3 x (5/2) - (15/2) - 7.5

However, since the number of beads must be a whole number, we need to adjust. In this case, Jamie cannot make a bracelet with exactly 5 red beads while maintaining the ratio of 3:2. She would need to choose a different number of red beads that allows for a whole number of black beads according to the established ratio.

In conclusion, to maintain the relationship of black beads to red beads, Jamie cannot make a bracelet with exactly 5 red beads. The number of red beads chosen must allow for a whole number of black beads based on the given ratio.

Answer:

Zeros : 1 , -1, 3

Degree : 4

End Behaviour : At x-> ∞ f(x) -> ∞ and x->-∞ f(x) -> ∞

Y - intercept : -3

Extra Points: (0,-3), (2,-3)

Step-by-step explanation:

f(x) = 0 to find the zeros

[tex]Therefore (x+1)(x-1)^{2} (x-3) = 0[/tex]

Clearly x = -1,1,3

Here 1 is a repeating root as it is (x-1)²

Degree is highest power of x in f(x)

Clearly it is x*x²*x = x⁴ is the maximum power of x

Thus degree is 4

Looking at end behavior we substitute x->∞ and x-> -∞

Clearly f(x)>0 as all terms are positive and f(x)->∞

Similarly when x->-∞

f(x)>0 as 2 terms are -ve and their product is positive thus f(x)-> ∞

Y-Intercept is f(0)

f(0) = (0+1)(0-1)²(0-3) = 1*1*-3 = -3

Thus Y-Intercept is -3

Substitute x = 0 , 2 for extra points

Thus f(0) = -3

and f(2) = -3

Thus points on the graph (0,-3), (0,2)

We can use all this information to draw a graph remember that 1 is a repeating root so that will be a point of minima. The graph is a parabola that passes through x-axis at x = -1, 3.

Answer:

OPTION C

Step-by-step explanation:

An element in the domain should be mapped to exactly one element on the co-domain. Also, every element in the domain should be mapped to an element in the co-domain.

These two conditions are satisfied to call a relation, a function.

Two different elements in the domain can be mapped to the same element in the co-domain. But the same element in the domain cannot be mapped to two different elements in the co-domain.

A) (1,2), (3,4), (5,6), (3,-4)

Here, the element '3' is mapped to 4 and -4. So, this is not a function.

B) (8,4), (4,3), (2,2), (8,1)

'8' is mapped to 4 and 1. So, it is not a function.

C) (2,5), (3,10), (4,15), (5,20)

All the elements in the domain are mapped to an element in the co-domain.  Also, every element in the domain has exactly one image in the co-domain. So, this relation is a function.

D) (2,4), (2,3), (2,1), (2,0)

The element '2' has more than one image. Clearly, it contradicts the definition of a function.

So, only OPTION C is the answer.

Answer:

-3x + 8y - 96 = 0

Step-by-step explanation:

Standard form is ax + by + c = 0.

Converting from standard to slope-intercept form:

ax + by + c = 0

by = -ax - c

y = -a/b x - c/b

Compare the conversion formula to y = 3/8 x + 12.

In the equation, the slope is 3/8, which is the result of -a/b.

a= -3 and b=8

In the equation, 12 is a result of -c/b.

If b is 8:

-c/b = 12

-c/8 = 12

-c = 96

c = -96

Test a= -3 and b=8 and c= -96 in standard form converts to y=3/8 x+ 12

ax + by + c = 0

-3x + 8y - 96 = 0

-3x + 8y = 96

8y = 3x + 96

y = 3/8 x + 96/8

y = 3/8 x +12

This is correct. Therefore a= -3, b=8 and c= -96.

The standard form is -3x + 8y - 96 = 0

Answer: The correct graph is the bottom left graph.

Step-by-step explanation:

Given function is f(x)=ceil(x+1)

To plot graph of f(x) in interval of(-3,3) :

ceil(x+1) is ceiling function

The output of ceil(x) is least integer greater than x

for example ceil(5.5)=6

For an interval of (-3,-2):

Take x=(-2.4)

x+1=(-1.4)

y=f(x)=ceil(x+1)=(-1)

Similarly,

For an interval of (-2,-1):

Take x=(-1.4)

x+1=(-0.4)

y=f(x)=ceil(x+1)=(0)

For an interval of (-1,0)

y=f(x)=1

For an interval of (0,1)

y=f(x)=2

For an interval of (1,2)

y=f(x)=3

For an interval of (2,3)

y=f(x)=4

Thus, The correct graph is the bottom left graph.
