Answer:

Similar by SAS.

Step-by-step explanation:

SSS - sides proportional.

AA -Same angles and sides should be proportional. In this case, the angles are different, so they are not similar by sss.

SAS - One equal angle, and sides proportional. Happens here. So the answer is similar by SAS.

Given:

Point = (1,-4), Slope - 8

Point = (1,5), Slope =1

To find:

The slope-intercept forms of the given lines.

Solution:

The slope intercept form of a line is:

\(y=mx+b\)

The point slope form is:

\(y-y_1=m(x-x_1)\)

where, m is the slope of the line.

We have, Point = (1,-4), Slope - 8. So, the equation of the line is:

\(y-(-4)=-8(x-1)\)

\(y+4=-8x+8\)

\(y=-8x+8-4\)

\(y=-8x+4\)

Therefore, the correct option is B.

We have, Point = (1,5), Slope =1. So, the equation of the line is:

\(y-5=1(x-1)\)

\(y-5=x-1\)

\(y=x-1+5\)

\(y=x+4\)

Therefore, the correct option is D.

Answer:

C. Translation 5 units left and 2 units down

Step-by-step explanation:

Let's take a look at A', which is (0, 0). This is the result of A, which is (5, 2) being transformed somehow. Notice that the x-coordinate moved 5 units to the left (from 5 to 0, which means we subtract 5 from 5). And, notice that the y-coordinate moved 2 units down (from 2 to 0, so we subtract 2 from 2).

Look to see if this works for the other two points:

B(6, 1): if we subtract 5 from the x-coordinate 6, we get 6 - 5 = 1, which matches the x-coordinate of the image B'. If we subtract 2 from the y-coordinate of B, which is 1, we get 1 - 2 = -1, which also matches the y-coordinate of B'. So, this works.

C(4, 5): if we subtract 5 from the x-coordinate 4, we get 4 - 5 = -1, which matches the x-coordinate of the image C'. If we subtract 2 from the y-coordinate of C, which is 5, we get 5 - 2 = 3, which also matches the y-coordinate of C'. So, this again works.

Therefore, we know that the transformation is a translation 5 units left and 2 units down, or C.

A picture will be shown below of a graph with the points in the table.

We only need to use (5, 2) and (0, 0) to solve this problem.

We take both points and see what it took for the old point to get to where the new point is (Shown in picture below).

Therefore, the answer is [ C. Translation 5 units left and 2 units down ]

The width of the rectangular walkway is 3 feet around.

The walkway has a uniform width around the rectangle.

Let the width of walkway be x

The total length of the garden and walkway will be (12+2x) feet

The total width of the walkway and garden would be (8+2x) feet

Area of the garden and the walkway together are 252 square

Let’s express this mathematically:

(8+2x)(12+2x) = 252

Let’s open the brackets;

96+ 16x+ 24x + 4x^2 = 252

4x^2 + 40x + 96 = 252

4x^2 + 40x + 96-252 = 0

4x^2 + 40x - 156 = 0

Let’s divide all through by 10. We have;

x^2 + 10x -39 = 0

X^2 +13x-3x-39 = 0

x(x + 13) -3(x+ 13) = 0

(x-3)(x + 13) = 0

x -3 = 0 or x + 13 = 0

x = 3 or -13

We ignore x = -13 since width cannot be negative in size

Therefore, the width of the rectangular walkway is 3 feet around.

Answer:

Answer B as the difference between the values is the same

Answer:

1.   2x + 8y = 10xy

2.   13ab + 15ab = 28ab

Step-by-step explanation:

  This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

The equation in slope-intercept form for the line is y = -3/2x + 5.

We have,

In slope-intercept form,

The equation of a line is written as y = mx + b, where m represents the slope of the line and b represents the y-intercept (the point where the line crosses the y-axis).

Given that the slope is -3/2 and the y-intercept is 5, we can substitute these values into the equation to obtain:

y = -3/2x + 5.

This equation tells us that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 3/2 units.

The y-intercept of 5 indicates that the line passes through the point (0, 5).

Thus,

The equation in slope-intercept form for the line is y = -3/2x + 5.

Answer:

248 cm^2

Step-by-step explanation:

in order to get the figures surface area you only need to find the area of all 6 sides

in this case the two ends are 4 by 6

the front and back are 10 by 6

and the top and bottom are 10 by 4

this would mean that we need to multiply

(4*6)*2

(10*6)*2

(10*4)*2

which would look like

(4*6)*2= (24)*2= 48

(10*6)*2= (60)*2=120

(10*4)*2= (40)*2=80

and finally the sum of the equations is the surface area of the figure

48+120+80=248

Since S satisfies both defining properties of an ideal in R, we can conclude that S is indeed an ideal in R.

To prove that the subset S = {λ1r1 +···+ λnrn | λ1,...,λn ∈ R} is an ideal in R, we need to show that it satisfies the two defining properties of an ideal:

1. S is a subgroup of R under addition.
2. S is closed under multiplication by elements of R.

First, let's show that S is a subgroup of R under addition.

- Closure under addition: Let x,y ∈ S, so that x = λ1r1 + ··· + λnrn and y = μ1r1 + ··· + μnrn for some λi,μi ∈ R. Then their sum is x + y = (λ1 + μ1)r1 + ··· + (λn + μn)rn, which is in S since each coefficient is still in R.

- Additive inverse: Let x ∈ S, so that x = λ1r1 + ··· + λnrn for some λi ∈ R. Then its additive inverse is -x = (-λ1)r1 + ··· + (-λn)rn, which is also in S since each coefficient is still in R.

Therefore, S is a subgroup of R under addition.

Next, let's show that S is closed under multiplication by elements of R.

- Closure under left multiplication: Let r ∈ R and x ∈ S, so that x = λ1r1 + ··· + λnrn for some λi ∈ R. Then their product is rx = (rλ1)r1 + ··· + (rλn)rn, which is in S since each coefficient is still in R.

- Closure under right multiplication: This follows from the distributive property of multiplication over addition.

Therefore, S is closed under multiplication by elements of R.

Since S satisfies both defining properties of an ideal in R, we can conclude that S is indeed an ideal in R.

Work Shown:

If cos(x) = 8/17, then sin(x) = 15/17. Use the identity \(\sin^2(\text{x}) + \cos^2(\text{x}) = 1\) to determine this.

If cos(y) = 3/5, then sin(y) = 4/5 using that same identity.

So,

sin(x-y) = sin(x)cos(y) - cos(x)sin(y)

sin(x-y) = (15/17)*(3/5) - (8/17)*(4/5)

sin(x-y) = 45/85 - 32/85

sin(x-y) = (45 - 32)/85

sin(x-y) = 13/85

Answer:

he value of the integral ∫ y tan(x) dx is y sin(x) + C.

Step-by-step explanation:

Property 8 of integrals states that if we have an integral of the form ∫ f(x) g'(x) dx, it can be rewritten as ∫ f(x) dg(x), where g(x) is an antiderivative of g'(x).

In this case, we have the integral ∫ y tan(x) dx. By applying Property 8, we can rewrite it as ∫ y d(sin(x)).

Now, integrating with respect to y while treating sin(x) as a constant, we get:

∫ y d(sin(x)) = y sin(x) + C,

where C is the constant of integration.

So, using Property 8, the value of the integral ∫ y tan(x) dx is y sin(x) + C.

The correct statement for the correlation between X1 and X2 is -0.9 are the estimated value of the slope of X1 may be very different from the true value of the slope and there is collinearity in the regression model. Options A and B are the correct answer.

A high correlation between X1 and X2 indicates that these variables are highly related and may contain similar information. This means that including both variables in the regression model may lead to collinearity, which can cause problems in estimating the true effects of each variable on the outcome Y.

In particular, when there is collinearity in the model, the estimated value of the slope of X1 may be very different from the true value of the slope. This is because the collinearity makes it difficult to distinguish the effects of X1 and X2 on the outcome, leading to large standard errors and reduced precision in the estimation.

Finally, we can integrate each term of this expression to obtain the solution to the original indefinite integral. The final solution is (1/2)x - (1/2)ln(x² + 1) + C, where C is the constant of integration.

To solve the indefinite integral of the given function, we need to make use of substitution. One of the most appropriate substitutions for this integral is u = x² + 1. By making this substitution, we can simplify the integral to the point where we can apply the power rule of integration. The derivative of u with respect to x is du/dx = 2x. Therefore, we can express dx in terms of du by multiplying both sides of this equation by dx/2. This gives us dx = du/2x. Substituting this into the original integral, we get ∫(x²)/(x²+1) dx = ∫(u-1)/(2u) du. We can simplify this expression to get ∫(1/2) - (1/2u) du.  Overall, this substitution allows us to simplify the integral and arrive at a more manageable form. This demonstrates the power and utility of using substitution when dealing with complex integrals.
