Answer:
-4 is the mimumum of y=-3+cos(x+4)
Step-by-step explanation:
The minimum value of y=cos(x) is -1.
The minimum value of y=cos(x+4) is still -1; the +4 inside the cosine function only affected the horizontal shift.
The minimum value of y=-3+cos(x+4) is -3-1 which is -4. This brought the graph down 3 units so if the minimum was previously -1 and it got brought down 3 units then it's new minimum is -4.

2) Reflect over the x-axis, rotate 180°, reflect over the x-axis
3) Rotate 180°, reflect over the y-axis, reflect over the line y=x
4) Reflect over the y-axis, reflect over the x-axis, rotate 180°
Answer:
4) Reflect over the y-axis, reflect over the x-axis, rotate 180°
Step-by-step explanation:
Since, the rule of 180° rotation,
[tex](x,y)\rightarrow (-x,-y)[/tex]
Rule of reflection over x-axis,
[tex](x,y)\rightarrow (x,-y)[/tex]
Rule of reflection over y-axis,
[tex](x,y)\rightarrow (-x,y)[/tex]
Rule of reflection over line y = x,
[tex](x,y)\rightarrow (y,x)[/tex]
∵ In the set of reflection,
Rotate 180°, reflect over the x-axis, reflect over the line y=x,
[tex](x,y)\rightarrow (-x,-y)\rightarrow (-x,y)\rightarrow (y,-x)[/tex]
Reflect over the x-axis, rotate 180°, reflect over the x-axis,
[tex](x,y)\rightarrow (x,-y)\rightarrow (-x,y)\rightarrow (-x,-y)[/tex]
Rotate 180°, reflect over the y-axis, reflect over the line y=x,
[tex](x,y)\rightarrow (-x,-y)\rightarrow (x,-y)\rightarrow (-y,x)[/tex]
Reflect over the y-axis, reflect over the x-axis, rotate 180°,
[tex](x,y)\rightarrow (-x,y)\rightarrow (-x,-y)\rightarrow (x,y)[/tex]
Hence, the set of reflections and rotations that would carry rectangle ABCD onto itself is,

What is the factored form of the polynomial?
x2 − 15x + 36
(x − 4)(x − 9)
(x − 3)(x − 12)
(x + 4)(x + 9)
(x + 3)(x + 12)
Answer:
(x - 3)(x - 12)
Step-by-step explanation:
Given
x² - 15x + 36
Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (- 15)
The factors are - 3 and - 12, since
- 3 × - 12 = + 36 and - 3 - 12 = - 15, hence
x² - 15x + 36 = (x - 3)(x - 12) ← in factored form
The factored form of the polynomial x² − 15x + 36 is (x − 3)(x − 12). This can be obtained by using the steps of splitting the middle term method.
Find the factored form using splitting the middle term:Given the polynomial, x² − 15x + 36
Step 1:First we should multiply first term and last term, x²×36=36x²Step 2:This product ,that is 36x², should be slit such that the factors sum is the middle term, -15x.(-3x)×(-12x)=36x² and (-3x)+(-12x)= - 15x
-3x and -12x are the required factors of 36x²
Step 3:Substitute the factors in the place of middle term,x² - 3x - 12x+36
Step 4:Take common terms from the first two terms and last two terms,x² - 3x - 12x+36 = x(x - 3) - 12(x - 3)
=(x - 3)(x - 12)
Hence the factored form of the polynomial x² − 15x + 36 is (x − 3)(x − 12).

A ball has a surface area of 26.87 square feet. To the nearest tenth of a foot, what is the radius of the ball? Use π = 3.14.
Answer:
about 1.5 feet
Step-by-step explanation:
First we need to note the equation to find the surface area of a sphere. This is 4πr^2.
4πr^2=Surface Area
4πr^2=26.87
4(3.14)r^2=26.87 Substitute
r^2=26.87/(4*3.14) Divide
r^2=26.87/12.56 Simplify
r=√(26.87/12.56) Find square root of both sides
r≈1.5 Do the calculations
So the radius of the ball is about 1.5 feet.
Answer:1.5 ft
Step-by-step explanation:
Given
Surface area of ball=[tex]26.87 ft^2 [/tex]
And we know surface area of ball is =[tex]4\pi r^2[/tex]
Equating
[tex]26.87=4\times 3.14\times r^2 [/tex]
[tex]r^2=2.1393[/tex]
[tex]r=1.4626\approx 1.5 [/tex]
Which statement is true about the factorization of 30x2 +40xy+51y2
Answer:
prime
not factorable over the reals
Step-by-step explanation:
30x^2+40xy+51y^2 is not factorable (also know as prime)
because the discriminant is negative.
That is when I computed b^2-4ac, in this case 40^2-4(30)(51)=-4520.
If the discriminant is negative, then it isn't factorable over the reals.
What happens when you reflect a shape over the x-axis and then the y-axis. What is the one transformation that could have been performed to achieve the same result? A degree rotation.
Reflecting a shape over the x-axis and then the y-axis is equivalent to a 180-degree rotation around the origin.
When a shape is reflected over the x-axis, any point (x, y) on the shape will have its y-coordinate inverted, becoming (x, -y). If this reflected shape is then reflected over the y-axis, the x-coordinate is inverted, so (x, -y) becomes (-x, -y). The same final position of the shape could have been achieved by a single transformation: rotating the shape 180 degrees around the origin.
Mathematically, the combination of these two reflections can be represented by matrices and is equivalent to the composition of two reflection transformations. The reflection across the x-axis can be represented by a matrix that inverts the sign of the y-coordinate and reflection across the y-axis can be represented by a matrix inverting the x-coordinate. Together, these operations are equivalent to a 180-degree rotation around the origin.

Options:

2. 3x-4y=-4
3.4x-3y=-3
4. y-2=-3/4(x-4)
5. y+ 2 = 3/4(x + 4)
Please help ASAP thank you ! :)
Answer:
2 and 5
Step-by-step explanation:
The slope-intercept form of a line is y=mx-b where m is slope and b is y-intercept.
The point-slope form of a line is y-y1=m(x-x1) where m is the slope and (x1,y1) is a point on the line.
The standard form a line is ax+by=c.
So anyways parallel lines have the same slope.
So if we are looking for a line parallel to 3x-4y=7 then we need to know the slope of this line so we can find the slope of our parallel line.
3x-4y=7
Goal: Put into slope-intercept form
3x-4y=7
Subtract 3x on both sides:
-4y=-3x+7
Divide both sides by -4:
[tex]y=\frac{-3}{-4}x+\frac{7}{-4}[/tex]
Simplify:
[tex]y=\frac{3}{4}x+\frac{-7}{4}[/tex]
So the slope of this line is 3/4. So our line that is parallel to this one will have this same slope.
So we know our line should be in the form of [tex]y=\frac{3}{4}x+b[/tex].
To find b we will use the point that is suppose to be on our new line here which is (x,y)=(-4,-2).
So plugging this in to solve for b now:
[tex]-2=\frac{3}{4}(-4)+b[/tex]
[tex]-2=-3+b[/tex]
[tex]3-2=b[/tex]
[tex]b=1[/tex]
so the equation of our line in slope-intercept form is [tex]y=\frac{3}{4}x+1[/tex]
So that isn't option 1 because the slope is different. That was the only option that was in slope-intercept form.
The standard form of a line is ax+by=c and we have 2 options that look like that.
So let's rearrange the line that we just found into that form.
[tex]y=\frac{3}{4}x+1[/tex]
Clear the fractions because we only want integer coefficients by multiplying both sides by 4.
This gives us:
[tex]4y=3x+4[/tex]
Subtract 3x on both sides:
[tex]-3x+4y=4[/tex]
I don't see this option either.
Multiply both sides by -1:
[tex]3x-4y=-4[/tex]
I do see this as a option. So far the only option that works is 2.
Let's look at point slope form now.
We had the point that our line went through was (x1,y1)=(-4,-2) and the slope,m, was 3/4 (we found this earlier).
y-y1=m(x-x1)
Plug in like so:
y-(-2)=3/4(x-(-4))
y+2=3/4 (x+4)
So option 5 looks good too.
Answer:
OPTION 2.
OPTION 5.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
Given the line [tex]3x - 4y = 7[/tex], solve for "y":
[tex]3x - 4y = 7\\\\-4y=-3x+7\\\\y=\frac{3}{4}x-\frac{7}{4}[/tex]
The slope of this line is:
[tex]m=\frac{3}{4}[/tex]
Since the slopes of parallel lines are equal, the slope of the other line is:
[tex]m=\frac{3}{4}[/tex]
Substitute the slope and the given point into [tex]y=mx+b[/tex] and solve for "b":
[tex]-2=\frac{3}{4}(-4)+b\\\\-2+3=b\\\\b=1[/tex]
Then, the equation of this line in Slope-Intercept form is:
[tex]y=\frac{3}{4}x+1[/tex]
The equation of the line in Standard form is:
[tex]Ax+By=C[/tex]
Then, manipulating the equation [tex]y=\frac{3}{4}x+1[/tex] algebraically, we get:
[tex]y-1=\frac{3}{4}x\\\\4(y-1)=3x\\\\4y-4=3x\\\\-4=3x-4y\\\\3x-4y=-4[/tex]

[tex]f(x) = x^2 - 5[/tex]
[tex]g(x) = 4x - 4[/tex]
Finding [tex] ( f - g ) ( x ) [/tex]:
[tex] ( f - g ) ( x ) [/tex] [tex]= (x^2-5)-(4x-4) = x^2-4x-5+4[/tex]

all of the following expressions have the same value except... -4/5-1/5 -(4/5+1/5) -4/5+ -1/5 -4/5-(-1/5)
Answer:
-4/5-(-1/5)
Step-by-step explanation:
-4/5-1/5 is equivalent to -4/5+-1/5 which equals -1
-(4/5+1/5) when you add the expression in the parenthesis you get 1 and when you multiply that by -1 you get -1
-4/5+ -1/5 this is like the first choice so it equals -1
-4/5-(-1/5) this expression is the equivalent to -4/5+1/5 which gives you -3/5
The last option is -3/5 while the others are -1 which it the one with the different value
All of the expressions have the same value except -4/5 - (-1/5).
Explanation:In this case, all of the expressions have the same value except -4/5 - (-1/5).
To simplify each expression:
-4/5 - 1/5 can be simplified to -5/5 which is equal to -1.-(4/5 + 1/5) can be simplified to -5/5 which is also equal to -1.-4/5 + (-1/5) can be simplified to -5/5 which is still equal to -1.Finally, -4/5 - (-1/5) can be simplified to -4/5 + 1/5. Adding these fractions gives us -3/5.Therefore, the expression that has a different value is -4/5 - (-1/5).

If tan^3(theta) -1/tan(theta)-1 - sec^2(theta) + 1 = 0 find cot(theta)
[tex]\tan^3\theta-\dfrac1{\tan\theta-1}-\sec^2\theta+1=0[/tex]
Recall that [tex]\tan^2\theta+1=\sec^2\theta[/tex], so we can write everything in terms of [tex]\tan\theta[/tex]:
[tex]\tan^3\theta-\dfrac1{\tan\theta-1}-\tan^2\theta=0[/tex]
Let [tex]x=\tan\theta[/tex], so that
[tex]x^3-\dfrac1{x-1}-x^2=0[/tex]
With some rewriting we get
[tex]x^3-x^2-\dfrac1{x-1}=0[/tex]
[tex]x^2(x-1)-\dfrac1{x-1}=0[/tex]
[tex]\dfrac{x^2(x-1)^2-1}{x-1}=0[/tex]
Clearly we cannot have [tex]x=1[/tex], or [tex]\tan\theta=1[/tex].
The numerator determines when the expression on the left reduces to 0:
[tex]x^2(x-1)^2-1=0[/tex]
[tex]x^2(x-1)^2=1[/tex]
[tex]\sqrt{x^2(x-1)^2}=\sqrt1[/tex]
[tex]|x(x-1)|=1[/tex]
[tex]x(x-1)=1\text{ or }x(x-1)=-1[/tex]
Completing the square gives
[tex]x(x-1)=x^2-x=x^2-x+\dfrac14-\dfrac14=\left(x-\dfrac12\right)^2-\dfrac14[/tex]
so that
[tex]\left(x-\dfrac12\right)^2=\dfrac54\text{ or }\left(x-\dfrac12\right)^2=-\dfrac34[/tex]
The second equation gives no real-valued solutions because squaring any real number gives a positive real number. (I'm assuming we don't care about complex solutions.) So we're left with only
[tex]\left(x-\dfrac12\right)^2=\dfrac54[/tex]
[tex]\sqrt{\left(x-\dfrac12\right)^2}=\sqrt{\dfrac54}[/tex]
[tex]\left|x-\dfrac12\right|=\dfrac{\sqrt5}2[/tex]
which again gives two cases,
[tex]x-\dfrac12=\dfrac{\sqrt5}2\text{ or }x-\dfrac12=-\dfrac{\sqrt5}2[/tex]
[tex]x=\dfrac{1+\sqrt5}2\text{ or }x=\dfrac{1-\sqrt5}2[/tex]
Then when [tex]x=\tan\theta[/tex], we can find [tex]\cot\theta[/tex] by taking the reciprocal, so we get
[tex]\boxed{\cot\theta=\dfrac2{1+\sqrt5}\text{ or }\cot\theta=\dfrac2{1-\sqrt5}}[/tex]

Answer: The 1-kg ball has 1/10 as much kinetic energy as the 10-kg ball.
Step-by-step explanation:
Option (a) - "less momentum" - accurately describes the relationship between the momentum of the 1 kg ball compared to the 10 kg ball.
The momentum of an object is directly proportional to its mass. When comparing a 10 kg ball to a 1 kg ball traveling at the same speed, the 10 kg ball has more momentum due to its greater mass. Since momentum is determined by both mass and velocity, and the velocity is the same for both balls, the difference in momentum is solely due to the difference in mass. The 10 kg ball has ten times the mass of the 1 kg ball. Therefore, the 1 kg ball has less momentum compared to the 10 kg ball. In fact, it has one-tenth of the momentum of the 10 kg ball.
Complete question: A 10 kg ball is traveling at the same speed as a 1 kg ball. Compared with the 10 kg ball, the 1 kg ball has
a-less momentum.
b-twice momentum.

8. D) 2x + 89. C) 6x + 32 = 15810. 50 ftStep-by-step explanation:
Look at the picture.
9. The perimeter of the rectangle l × w:
P = 2l + 2w
Substitute l = 2x + 8 and w = x + 8:
P = 2(2x + 8) + 2(x + 8) use the distributive property
P = (2)(2x) + (2)(8) + (2)(x) + (2)(8)
P = 4x + 16 + 2x + 16 combine like terms
P = (4x + 2x) + (16 + 16)
P = 6x + 32
10. Solve the equation:
6x + 32 = 158 subtract 32 from both sides
6x = 126 divide both sides by 6
x = 21
Put the value of x to the expression 2x + 8:
2(21) + 8 = 42 + 8 = 50
In a triangle, the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third angle is four times the measure of the second angle. If the total number of degrees in a triangle is 180, what is the measure of the largest angle?
Answer:
First angle = 50, second angle = 26 and the third angle = 104 degrees.
Largest angle is 104 degrees.
Step-by-step explanation:
Let the second angle be x degrees, the the first will be x + 24 and the third is
4x degrees.
x + x+ 24 + 4x = 180
6x = 180 - 24
6x = 156
x = 26
so the other 2 angles are 26 + 24 = 50 and 4*26 = 104 degrees.
Triangle is the polygon with three edges, three vertices and three angle. The total number of degrees in a triangle is always 180 degrees. The value of the largest angle in the given triangle is 104 degrees.
Given-
Let The measure of the second angle is x degrees.
The measure of the first angle is 24 degrees more than the measure of the second angle. Thus first angle is (24+x) degrees.
The third angle is four times the measure of the second angle. Thus the measure of the third angle is 4x.
What is triangle?Triangle is the polygon with three edges, three vertices and three angle. The total number of degrees in a triangle is always 180 degrees.
As we know that the sum of the all the three angle in the triangle is 180 degrees. Therefore,
[tex](24+x)+x+4x=180[/tex]
[tex]6x=124-48[/tex]
[tex]6x=156[/tex]
[tex]x=\dfrac{156}{6}[/tex]
[tex]x=26[/tex]
Hence the the measure of the second angle is 26 degrees. Now The measure of the first angle is 24 degrees more than the measure of the second angle. Thus,
[tex]=24+26[/tex]
[tex]=50[/tex]
Hence measure of the first angle is 50 degrees. Now the third angle is four times the measure of the second angle. Thus,
[tex]=4\times 26=104[/tex]
Hence, the measure of the third angle is 104 degrees.
Thus the value of the largest angle in the given triangle is 104 degrees.

Which best describes the graph of the function f(x)=4x ?
Answer:
F
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
where m = slope, and b = y-intercept.
This line has equation
y = 4x
When we compare y = 4x with y = mx + b, we see that m = 4, and b = 0.
This line intersects the y-axis (the y-intercept) at y = 0, which is the origin. The slope is positive, so it slopes up to the right.
Answer: F
The function f(x) = 4x is a linear function, and when graphed, it will produce a straight line with a slope of 4. The graph demonstrates the dependence of y on x and it's an example of a line graph.
Explanation:The question asks for a description of the graph of the function f(x) = 4x.
The function f(x) = 4x is a linear function, which means it creates a straight line when graphed. The number 4 in the function is the slope of the line. This value indicates that for each increase by 1 in the x value, the y value will increase by 4.
This demonstrates the dependence of y on x. So, a graph of this function would be a straight line that slopes upward from left to right, starting at the origin (0,0) and increasing by 4 in the y direction for each step of 1 in the x direction. This is a typical representation of a linear function demonstrating the relationship between two variables on a line graph.

d/dx (28000-50x²-400x)
Answer:
[tex]-100x - 400[/tex]
Step-by-step explanation:
The derivative of a sum is the sum of the derivatives by the sum rule, and this also extends to differences by the constant multiple rule
[tex]\dfrac{d}{dx}(28000 - 50x^2 - 400x) = \dfrac{d}{dx}(28000) - \dfrac{d}{dx}(50x^2) - \dfrac{d}{dx}(400x)[/tex]
By the constant multiple rule, we have
[tex]= \dfrac{d}{dx}(28000) - 50\dfrac{d}{dx}(x^2) - 400\dfrac{d}{dx}(x)[/tex]
The derivative of any constant is 0.
The power rule says that for any real number [tex]n[/tex], [tex]\frac{d}{dx} x^n = nx^{n-1}[/tex]. And note that [tex]x = x^1[/tex]. Thus we have
[tex]= 0 - 50(2)x - 400(1)x^0 = -100x - 400[/tex]
since [tex]x^0 = 1[/tex]
