Step-by-step explanation:
The function g(x) = (x + 2)2 + 4 is a transformation of the parent function f(x) = x2. Which of the following statements are true? Select all that apply.
A. Function g is the result of f being translated right 2 units and down 4 units.
B. Function g is the result of f being translated left 2 units and up 4 units.
C. The graph of function f opens upward.
D. The graph of function f opens downward.
E. The graph of function f is compressed by a factor of 2.
Answer: B. Function g is the result of f being translated left 2 units and up 4 units. and C. The graph of function f opens upward.
Step-by-step explanation:
It is translated 2 units to the left and 4 units up because in the function of a(x-h)^2k, h represents the function going left of right and k representing the function going up and down. a represents it stretching if it is greater than 1 and compressing if less than 1 and if it is negative it reflects over the x axis however here nothing changed for the a so it did not stretch nor compress nor reflect over the x axis

∠c and ​∠d​ are vertical angles with m∠c=−3x 58 and m∠d=x−2. what is m∠d? enter your answer in the box. ​ °
D has a value of 13 using vertical angles.
What is a vertical angle?
When two lines intersect, the angles that face each other are called vertical angles.Instead of referring to them as being up-down, "vertical" in this context denotes that they share a vertex (corner point).Assuming that C and D constitute vertical angles
The formula is C = (-3x) + 58 and D = x - 2.
We must ascertain what D's measurement is.
Vertical angles are really a pair of opposing angles created when two lines cross.
A and B in the figure represent vertical angles. C and D are also.
Angles vertically are always congruent. Accordingly, in this illustration, A, B, and C, D
Therefore, value of C = D (-3x)+ 58 = x – 2
By assembling,
(-3x )- x = (-2) - 58
By doing more math, 4x = 60 (-4x = - 60)
4 x = 60/4 x = 15 when both sides are divided.
So, ∠D = (x - 2) and
= 15 - 2
So, ∠D = (x - 2) and
Consequently, D has a value of 13 using vertical angles.

use the trapezoidal rule, the midpoint rule, and simpson's rule to approximate the given integral with the specified value of n. (round your answers to six decimal places.) 4 0 ln(3 ex) dx, n
a. Trapezoidal Rule- 9.413607
b. Midpoint Rule-9.393861
c. Simpson's Rule -9.400407
a. We use n=8 for this integral, .Δt=4-0/8=0.5
Therefore the integral range is[0,0.5,1.0,1.5......3.0,3.5....4.0 ]

At α = 0.05, is there sufficient evidence that state senators are on average younger than 60.35 (the average age Senators in Washington)?
Answer:
There is not sufficient evidence to support the conclusion that senators are average younger than 60.35
Step-by-step explanation:
Given a simple random sample, the size is 40 senators.
Since the relevant statistic is the sample mean, 60.35 years.
Calculate t as:
[tex]t=\frac{\bar{x}-\mu_{\bar{x}}}{\frac{s}{\sqrt[]{n}}}[/tex]*Significance level is 0.05.

Since t=4.82 does not fall in the critical region bounded, we fail to reject the null hypothesis.

given the system y=-1/2x-1 and -1/4x+y+4=0 write the solution to the system on the space provided below as an ordered pair
The solution to the system of equations as an ordered pair is (4, -3).
We are given a system of linear equations in two variables. The first equation is y = (-1/2)x-1. The second equation is (-1/4)x+y+4 = 0.
We need to find the solution of the system of equations. We will use the substitution method to solve for the values of "x" and "y".
y = (-1/2)x - 1
(-1/4)x + y + 4 = 0
Substitute the value of "y" from the first equation into the second equation.
(-1/4)x + (-1/2)x - 1 + 4 = 0
(-3/4)x+3 = 0
(3/4)x = 3
x = 4
Substitute the value of "x" back into the first equation to get the value of "y".
y = (-1/2)x - 1
y = (-1/2)4 - 1
y = -2 - 1
y = -3

Cost/head/day x # of days in month = Cost/head/month
1. You have 5 horses and you feed 4.5 pounds of grain to each in one day. What is the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag?
2. You have 32 heads of horses, and each gets 1.5 pounds of grain per feeding. You feed grain twice a day, once in the morning and once in the evening. If you feed grain that costs $13 per 50lb bag, then is the cost per head per month?
3. You have 12 heads of horses, and each gets 2.5 pounds of grain per feeding. You feed grain twice a day, once in the morning and once in the evening. If you feed grain that costs $13 per 50lb bag, then is the cost per head per month?
Solving the questions from the given equations
1)the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2
2) The cost per head per month is $23.4
3) The cost per head per month is $39
What is Equation?
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.
1) The grains use feed for one horse = 4.5pound
The cost of 1 bag of grain = $27 per 50lb
The cost of 1lb grain = $0.54
Now the monthly cost of the grain will be:
Cost/head/day x # of days in month = Cost/head/month
$0.54 x 30 = $16.2
Hence, the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2
2) The amount of grain use to feed for one head = 1.5pound
If the grain is feed twice a day = 1.5 x 2
= 3.0
The cost of the grain = $13 per 50lb
The cost of 1lb grain = 13 / 50
= $0.26
The cost of grain feed in one day = 0.26 x 3
= $0.78
The cost of per head per month =
0.78 x 30 = $23.4
Hence, The cost per head per month is $23.4
3)The amount of grain use to feed for one head = 2.5pound
If the grain is feed twice a day = 2.5 x 2
= 5pounds
The cost of the grain = $13 per 50lb
The cost of 1lb grain = 13 / 50
= $0.26
The cost of grain feed in one day = 0.26 x 5
= $1.3
The cost of per head per month =
1.3 x 30 = $39
Hence, The cost per head per month is $39

The speed of the particle at time t=4 is 5 units.
We are given the x(t) vs time curve.
To find:
Speed of particle at t = 4
We know that the slope of x-t curve represents the speed of the particle.
To calculate the speed of the particle at t = 4, We will calculate the slope of the curve at t = 4
Slope = y₂ -y₁ / x₂ - x₁
Slope = 40 - 10 / 6 - 0
Slope = 30 /6
Slope = 5
From here we can say that the slope of the curve between x = 0 and x = 6 is equal to 5.

It is to be noted that the distance between P and ρ is: [tex]\approx[/tex] 15.52
This solution is arrived at using the Line Segment theorem. See further explanation below.
What is the line segment theorem?The length of the line segment connecting two points in a plane is defined as the distance between two points. The method for calculating the distance between two locations is often written as
[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]
Hence, since we have ρ is to contain two points, we will solve as follows:
Distance between ρ and P where ρ is (0, -3) and (7,4)
we have to multiply the coordinates.
To multiply coordinates, you have to multiply the corresponding values.
That is
[tex]x_{1} \times x_{1} [/tex]
and
[tex]y_{1} \times y_{1}[/tex]
In this case:
x1 = 0
[tex]x_{1} = 0[/tex]
also
[tex]x_{1} = 7[/tex]
[tex]y_{1} = - 3[/tex]
also
[tex]y_{1} = 4[/tex]
Hence, for
[tex]x_{1} = 0 \times 7 = 0[/tex]
for
[tex]y_{1} = - 3 \times 4 = 12[/tex]
Hence, solving for the distance between P and ρ, we'd use coordinates of P as = (4, 3); and coordinates of ρ as = (0, -12)
Recall that distance is given as
[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]
Hence,
d = √((0-4)² + (-12-3))²)
[tex]d = \sqrt{{(( {0 - 4}^{2} }) + { (- 12 - 3)}^{2} } [/tex]
Expand the brackets
[tex]d = \sqrt{ { - 4}^{2} + ( { - 15}^{2} } )[/tex]
[tex]d = \sqrt{16 + 225} [/tex]
[tex]d = \sqrt{441} [/tex]
