Answer 1

Answer:

11)  [tex]y=-(x-6)^2+4[/tex]

12)  [tex]y=(x+5)^2[/tex]

Step-by-step explanation:

Vertex form of a parabola:  

[tex]y=a(x-h)^2+k[/tex]  where (h, k) is the vertex

Question 11

From inspection of the graph, the vertex is (6, 4)

[tex]\implies y=a(x-6)^2+4[/tex]

To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.

Using point (4, 0):

[tex]\implies a(4-6)^2+4=0[/tex]

[tex]\implies a(-2)^2+4=0[/tex]

[tex]\implies 4a=-4[/tex]

[tex]\implies a=-1[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=-(x-6)^2+4[/tex]

Question 12

From inspection of the graph, the vertex is (-5, 0)

[tex]\implies y=a(x+5)^2[/tex]

To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.

Using point (-3, 4):

[tex]\implies a(-3+5)^2=4[/tex]

[tex]\implies a(2)^2=4[/tex]

[tex]\implies 4a=4[/tex]

[tex]\implies a=1[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+5)^2[/tex]

Answer 2

We need equation of the parabolas

#1

Vertex is at (6,4)

One x intercept is present (4,0)

Now put that in vertex form of parabola

y=a(x-h)²+k0=a(4-6)²+44a+4=0a=-1

So

equation

y=-(x-6)²+4

#2

Vertex at (-5,0)

So equation

y=a(x+5)²+0=a(x+5)²

See the general quadratic equation having vertex (0,0) is shifted to (-5,0) means 5 units left .

So there is no a means a=

Equation remains same

y=(x+5)²

Find the volume. Show work!!

Answers

Step-by-step explanation:

this is a combined object :

there is the basic block at the bottom (21×21×17), and there is a pyramid on top of it.

so, we need to calculate the volume of both parts and add them for the total volume.

the volume of the block is, as mentioned :

21 × 21 × 17 (length×width×height) = 7,497 ft³

the volume of a pyramid is

length×width×height/3

which is in our case

21 × 21 × 9 / 3 = 21 × 21 × 3 = 1,323 ft³

so, the total volume is

7,497 + 1,323 = 8,820 ft³

A certain population has been shown to have a 2% annual growth rate. The
initial population is 75,000. What will the population be after 10 years

Answers

Answer:

The population after 10 years will be 90,000.

Explanation:

2% of 75,000 is 1,500

the population will grow by 1,500 each year.

so 1,500 times 10 is 15,000

so than we add 75,000 + 15,000

we get the answer of 90,000.

find the diameter of the object

Answers

Answer:

4

Step-by-step explanation:

The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in  the circle, to one directly across)

In this case, the radius is 2.

So, 2 x 2 = 4.

The diameter is 4.

Answer:-

4 in

Explanation:-

The diameter of a circle is twice its radius. Here the given radius is 2 in.

So diameter = 2 in × 2 in = 4 in

______________

Radius = Diameter/2

Diameter = Radius × Radius

Edit: It seems you want to find the measure of the angle at vertex C.

Consider two vectors x and y, the first of which begins at vertex C and ends at B, and the other begins at C and ends at A. We want to find the angle between x and y. If γ (gamma) is the measure of this angle, then

x • y = ||x|| ||y|| cos(γ)

Translating these vectors so that they start at the origin O, we get

C to B : x = (-2, 2) - (6, -2) = (-8, 4)

C to A : y = (6, 4) - (6, -2) = (0, 6)

Compute the dot product of x and y :

x • y = (-8, 4) • (0, 6) = 24

Compute their magnitudes:

||x|| = √((-8)² + 4²) = 4√5

||y|| = √(0² + 6²) = 6

Solve for γ :

cos(γ) = (x • y) / (||x|| ||y||)

cos(γ) = 24/(24√5)

cos(γ) = 1/√5

γ = arccos(1/√5) ≈ 63.4349°

Find the minimum value of the function f(x) = 1.5x2 + 10x + 12 to the nearest

Answer:

Step-by-step explanation:

Use derivative = 0 to find turning point(S)

D f(x) = 3x + 10 = 0

3x = - 10

X = - 10/3

When X = - 10/3

F(x) = 1.5(10/3)^2 - 10(10/3) + 12

= (3*10*10) / (2*3*3) - 100/3 +12

= 50/3 - 100/3 + 36/3

= - 14/3

A town with a population of 5,000 grows 3% per year. Find the population at the end of 10 years

Answers

6500 because if you take 3% of 5000 you get 150, so that’s 150 more people in the population per year. So you multiply 150 times 10 and you get 1500 and then you add your 5000 and get 6500.

The population at the end of the 10 years is 6,500.

Given that,

A town with a population of 5,000 grows 3% per year.

We need to find the population at the end of 10 years.

Based on the above information, the calculation is as follows:

= 5,000 + 1,500

= 6,500

Therefore we can conclude that the population at the end of the 10 years is 6,500.

Write an equation for the function graphed above.

Answers

The equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

How to determine the equation of the graph?

The graph is a secant graph, and it has the following form

[tex]y = a\sec(bx) + c[/tex]


From the graph, we have the following parameters:

Local minimum = 5 i.e. the minimum y value in the upper quadrantsLocal maximum = -1 i.e. the maximum y value in the lower quadrantTime, T = 6 i.e. the difference between corresponding points on the curve

The amplitude (a) is calculated using:

a = 0.5 *(Local minimum - Local maximum)

a = 0.5 *(5 + 1) = 3

The vertical shift (c) is calculated using:

a = 0.5 *(Local minimum + Local maximum)

a = 0.5 *(5 - 1) = 2

The period (b) is calculated using:

[tex]b = \frac{2\pi}{T}[/tex]

This gives

[tex]b = \frac{2\pi}{6}[/tex]

Evaluate

[tex]b = \frac{\pi}{3}[/tex]

Substitute the values of a, b and c in [tex]y = a\sec(bx) + c[/tex]

[tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

Hence, the equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

WORTH 20 POINTS

Answers

Answer:

a) 80
b) 56

Step-by-step explanation:

a) Calculate the volume of the the cup using volume of cylinder equation: [tex]V = \pi r^{2} h[/tex]

Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ([tex]in^3[/tex]).
You're given diameter, so use equation [tex]d/2 = r[/tex] to find radius.
Substituting these equations will give you: [tex]V = \pi (d/2)^2 h[/tex]
However, the given volume of the sink is 3000[tex]\pi[/tex], meaning that you should modify your results to match this value. Do not substitute [tex]\pi[/tex] for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 [tex]\pi[/tex]
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
[tex]Vsink / V cup =[/tex] # of cups.
Note the the [tex]\pi[/tex] will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.
