Answer:

The new function f(x) = (x-3)² +4

Step-by-step explanation:

Step(i):-

Given that the graph f(x) = x²

The given graph shifted up four units then the  new function

f(x) = x²+4

Step(ii):-

And again the graph shifted '3' units right then the graph is transformed to

f(x) = (x-3)² +4

Answer:

66 degrees

Step-by-step explanation:

if there are 66 one degree angles, all alll those together to get 66 degrees in total

The measure of the angle that is given with the given parameter is; 66°

We are told that ang angle is made up of 66 one-degree angles. Now, this means that each of the section of the main angle is one degree.

Thus, the value of 66 numbers of that angle will be;

66 * 1 = 66°

In conclusion, the measure of the angle is 66°.

Answer:

m=3, y = 3x - 2

Step-by-step explanation:

slope = rise / run

slope = 6/2

slope = 3

Answer:

The slope is 3.

Step-by-step explanation:

Slope is equal to rise over run. Let’s take a look at the points given to us on the graph.

To go from the leftmost point to the rightmost point, we rise (go up) 6 units, and then we run over (go right) 2 units. So we have:

Slope = Rise/run = 6/2

Now 6/2 is equal to 3, and that’s the slope.

Answer:

x = - 7.23

Step-by-step explanation:

3(x+6)= -3.68               Start with the breackets.

3x + 18 = - 3.69            Subtract 18 from both sides

3x = - 3.69 - 18

3x = -21.69                   Divide by 3

x = - 21.69/3

x = -7.23

Answer:

533.33 ft/min

Step-by-step explanation:

We are given that

x=3 feet

y=4 feet

Height of person,h=6 feet

[tex]\frac{dx}{dt}=400 ft/min[/tex]

Triangle ABC and A'B'C are similar because all right triangles are similar

By using similarity property

[tex]\frac{h'}{6}=\frac{7}{4}[/tex]

[tex]h'=10.5 feet[/tex]

[tex]x+y=3+4=7 feet[/tex]

[tex]\frac{h'}{6}=\frac{x+y}{y}[/tex]

[tex]\frac{10.5}{6}=\frac{x+y}{y}[/tex]

[tex]10.5y=6x+6y[/tex]

[tex]10.5y-6y=6x[/tex]

[tex]4.5y=6x[/tex]

Differentiate w.r.t t

[tex]4.5\frac{dy}{dt}=6\frac{dx}{dt}[/tex]

[tex]\frac{dy}{dt}=\frac{6\times 400}{4.5}ft/min[/tex]

[tex]\frac{dy}{dt}=533.33ft/min[/tex]

Hence, If the person is 6 feet tall and walks away from the lamp post at a speed of 400 feet per minute then his shadow moving at the rate 533.33 ft/min

Answer:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(5n^2\:-\:4nm\:-\:9m^2\right)\:+\:\left(7n^2\:+\:4nm\:+8m^2\right)[/tex]

Remove parentheses: (a) = a

[tex]=5n^2-4nm-9m^2+7n^2+4nm+8m^2[/tex]

Group like terms

[tex]=5n^2+7n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]5n^2+7n^2=12n^2[/tex]

[tex]=12n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]-4nm+4nm=0[/tex]

[tex]=12n^2-9m^2+8m^2[/tex]

Add similar elements:  [tex]-9m^2+8m^2=-m^2[/tex]

[tex]=12n^2-m^2[/tex]

Therefore, we conclude that:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]

Answer:

The calculated value z= 0.0063 does not  fall in the critical region  so we fail to reject the null hypothesis. And accept that the valve does not perform above the specifications.

Step-by-step explanation:

Given that

Population mean= μ = 8.0

Sample mean= x`= 8.1

Sample size= n= 250

Sample standard deviation= s= 1.00

Significance level= ∝ =0.01

The null hypothesis and alternate hypothesis are  

H0: μ < 8.0

Ha: μ ≥ 8.0  One tailed test

The claim is that the valve perform above the specifications

The critical value at 0.01 significance level for one tailed test is z > ±2.33

The test statistic z is used

z= x`- μ/ σ/√n

Z= 8.1-8.0/ 1/√250

z= 0.1/1/15.811

z= 0.0063

The calculated value z= 0.0063  does not fall in the critical region  so we fail to reject the null hypothesis.

The quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that during one game, the Dallas Cowboys punter was called upon to punt the ball eight times. On one of these punts, the punter struck the ball at his own 30-yard line. The height {h} of the ball above the field as a function of time {t} in seconds can be partially modeled by the following table -

{t}       0       0.6      1.2       1.8      2.4     3.0

h{t}   2.50  28.56  43.10  46.12  37.12  17.60

Using the graphing calculator, we can calculate the values as -

Mean of {x} : 1.5

Mean of {y} : 29.16666667

Correlation coefficient {r} : 0.9999376942

A : 2.55357143

B : 52.8875

C : -15.97519841

We can write the quadratic regression function as -

f(x) = A + Bx + Cx²

f(x) = 2.55357143 + 52.8875x - 15.97519841x²

Therefore, the quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².
