Step-by-step explanation:
Hi,
You will have to move the pre-image 15 units to the right. You're also going to have to flip the image horizontally (kind of like flipping it across the x-axis) and after that, you're going to have to flip it so that it's facing the left side.
1) 15 units right
2) Flip-up
3) Flip to the left
Hope this helps :)
Which value of b would make 16x? - bx + 25 a perfect square trinomial?
a. 4
b. 5
C. 20
d. 40
9514 1404 393
Answer:
d. 40
Step-by-step explanation:
Consider the square ...
(px +q)² = (px)² +2(px)(q) +q² = p²x² +2pqx +q²
Comparing this to your expression, you see ...
16 = p² ⇒ p = ±4
25 = q² ⇒ q = ±5
-b = 2pq = 2(±4)(±5) = ±40
The expression is a perfect square trinomial when b = 40.

Additional comment
When the linear term has a negative coefficient, we know the signs of the binomial terms are different. We conventionally write the square with the constant term in the binomial being negative:
16x² -40x +25 = (4x -5)²
(-10) x 0x ( -15 ) =

Answer:
[tex] \tan2\theta =-\dfrac{3\sqrt{13}}{2} [/tex]Step-by-step explanation:
To find:-
The value of [tex]\tan2\theta[/tex] .Answer:-
We are here given that the value of,
[tex]\longrightarrow \cos\theta=\dfrac{3}{\sqrt{22}} \\[/tex]
And we know that cosine is the ratio of base and hypotenuse. Therefore,
[tex]\longrightarrow \cos\theta =\dfrac{b}{h} \\[/tex]
So we can also say that,
[tex]\longrightarrow \cos\theta = \dfrac{b}{h}=\dfrac{3}{\sqrt{22}}\\[/tex]
Let us take the given ratio to be 3x:√22x . Now we may find out the value of perpendicular using Pythagoras theorem . The Pythagoras theorem is ,
Pythagoras theorem:-
In a right angled triangle the sum of squares of perpendicular and base is equal to the square of hypotenuse.Mathematically,
[tex]\longrightarrow \boxed{ \boldsymbol{p^2+b^2=h^2}} \\[/tex]
where the symbols have their usual meaning.
On substituting the respective values, we have;
[tex]\longrightarrow p^2+(3x)^2=(\sqrt{22}x)^2 \\[/tex]
[tex]\longrightarrow p^2 = 22x^2-9x^2\\[/tex]
[tex]\longrightarrow p^2=13x^2 \\[/tex]
[tex]\longrightarrow \boldsymbol{ p = \sqrt{13}x} \\[/tex]
Now again , we know that, tangent is defined as the ratio of perpendicular and base. Therefore,
[tex]\longrightarrow \tan\theta = \dfrac{p}{b} \\[/tex]
[tex]\longrightarrow \tan\theta = \dfrac{\sqrt{13}x}{3x}\\[/tex]
[tex]\longrightarrow \boldsymbol{ \tan\theta = \dfrac{\sqrt{13}}{3}}\\[/tex]
Now we may use a identity which is ,
[tex]\longrightarrow\boxed{ \boldsymbol{ \tan (2x)= \dfrac{2\tan x}{1-\tan^2 x}}}\\[/tex]
On substituting the respective values, we have;
[tex]\longrightarrow \tan2\theta = \dfrac{ 2\tan\theta}{1- \tan^2\theta}\\[/tex]
[tex]\longrightarrow \tan2\theta = \dfrac{2\bigg(\dfrac{\sqrt{13}}{3}\bigg)}{1-\bigg(\dfrac{\sqrt{13}}{3}\bigg)^2 } \\[/tex]
[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{1-\dfrac{13}{9}} \\[/tex]
[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{\dfrac{9-13}{9}} \\[/tex]
[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{\dfrac{-4}{9}} \\[/tex]
[tex]\longrightarrow \tan2\theta = -\dfrac{2\sqrt{13}\cdot 9}{3\cdot 4 } \\[/tex]
[tex]\longrightarrow \boxed{\boldsymbol{ \tan2\theta = -\dfrac{3\sqrt{13}}{2}}} \\[/tex]

30 points for this A special truck cleans the surface of the ice rink shown. The figure is composed of a square and two semicircles.
85 ft
85 Ft
If the truck cleans the entire surface, how many square feet of ice will the truck clean?
Use 3.14 for . Round your answer to the nearest tenth.
The truck will clean about
square feet of ice
Answer:
12897 square feet
Step-by-step explanation:
So first find the area of the square:
85 * 85 = 7225
Then, the two semi circles together is a full circle. Use the circle area formula,
A = πr^2
The radius (r) would be half the diameter of the circle. The diameter of the circle would be 85. So half of that is 42.5. The radius is 42.5
Now:
A = π(42.5)^2
A = 3.14(42.5)^2
A = 3.14(1806.25)
A = 5671.625
Lastly, add the two areas up for the square and circle:
7225 + 5671.625 = 12896.625
Round to nearest tenth: 12897

The mean annual starting salaries for college graduates with a degree in Operations Management was $65,000. We would like to determine whether or not this has decreased this year due to the pandemic. Data were collected over the annual starting salaries from a random sample of 40 Operations Management graduates. The average salary is $63,500 in the sample. Assume the standard deviation for the population of annual salaries is $3500. Let denote the average annual starting salaries among all Operations Management graduates this year.
Required:
What is the value of the appropriate test statistic?
Answer:
The value of the appropriate test statistic is Z = -2.71.
Step-by-step explanation:
The mean annual starting salaries for college graduates with a degree in Operations Management was $65,000. We would like to determine whether or not this has decreased this year due to the pandemic.
This means that the null hypothesis is that the mean stays the same, that is:
[tex]H_0: \mu = 65000[/tex]
The alternative hypothesis is that it decreased, that is:
[tex]H_a: \mu < 65000[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
65000 is tested at the null hypothesis:
This means that [tex]\mu = 65000[/tex]
Data were collected over the annual starting salaries from a random sample of 40 Operations Management graduates. The average salary is $63,500 in the sample. Assume the standard deviation for the population of annual salaries is $3500.
This means that [tex]n = 40, X = 63500, \sigma = 3500[/tex]
What is the value of the appropriate test statistic?
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{63500 - 65000}{\frac{3500}{\sqrt{40}}}[/tex]
[tex]Z = -2.71[/tex]
The value of the appropriate test statistic is Z = -2.71.

Given the arithmetic sequence of 21,
6, 9, 24,
find an explicit rule for the nth term.
Answer:
Step-by-step explanation:
The sequence you gave is not arithmetic. I'm assuming the sequence is
21, 6, -9, -24.
d is the common difference between adjacent terms.
a₂ = a₁ + d
6 = 21 + d
d = -15
nth term = a₁ + (n-1)d = 21 - (n-1)15

The function is valid in the interval of [0, 4) will be h(x) = 2x² – 3x + 10.
Then the value of the function will be
h(0) = 2(0)² – 3(0) + 10
h(0) = 10
Then the value of the function at x = 0 will be 10.
The value of the function, at x = 4, will be
The function is valid in the interval of [4, ∞) will be h(x) = (2)ˣ.
Then the value of the function will be
h(4) = (2)⁴
h(4) = 16
Then the value of the function at x = 4 will be 16.

Admission prices at a football game were $5 for adults and $ 2 for children.
The total value of the tickets sold was $2520, and 654 tickets were sold. How many adult
tickets and how many child tickets were sold?
Show all six steps.
Answer:
404 adult tickets were sold, and 250 child tickets.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that
x is the number of adult tickets sold.
y is the number of child tickets sold.
654 tickets were sold.
This means that
[tex]x + y = 654[/tex]
[tex]y = 654 - x[/tex]
Admission prices at a football game were $5 for adults and $ 2 for children. The total value of the tickets sold was $2520.
This means that
[tex]5x + 2y = 2520[/tex]
Since [tex]y = 654 - x[/tex]
[tex]5x + 2(654 - x) = 2520[/tex]
[tex]5x + 1308 - 2x = 2520[/tex]
[tex]3x = 1212[/tex]
[tex]x = \frac{1212}{3}[/tex]
[tex]x = 404[/tex]
[tex]y = 654 - x = 654 - 404 = 250[/tex]

Mrs. Spina bought 4 boxes of 8 pork chops. She set aside 12 and separated the rest into packs of4 to freeze. How many packs of chops did Mrs. Spina freeze
Step-by-step explanation:
Number of pork chops Mrs Spina bought =
Number of boxes x number of pork chops per box
= 4x8
= 32
Number of Pork chops to freeze = 32 - 12 (set aside) = 20
Number of packs of pork chops to freeze = Number of pork chops to freeze / pork chops per pack
= 20/4
= 5 packs.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 8 N acts on a certain object, the accelerstion of the object is 4 m/s2. If the acceleration of the object becomes 9 m/s?, what is the force?
Answer:
18N
Step-by-step explanation:
According to Newtons second law
F ∝ a
F = ka
k is the constant of proportionality
When a force of 8 N acts on a certain object, the acceleration of the object is 4 m/s2, hence;
8 = 4k
k = 8/4
k = 2
If a = 9m/s², F = ?
Recall F = ka
F = 2 * 9
F = 18N
Hence the force will be 18N
