. Line y = 2x + 1 is
transformed by a dilation
with a scale factor of 2 and centered at (3, 5). Is
the image the same line or a parallel line? How do
you know?

Answer:3

Step-by-step explanation:

The HCF of 3 and 9 is 3. To calculate the HCF (Highest Common Factor) of 3 and 9, we need to factor each number (factors of 3 = 1, 3; factors of 9 = 1, 3, 9) and choose the highest factor that exactly divides both 3 and 9 . i.e 3.

The distance from a point to a plane can be found by using the formula d = |ax + by + cz + d|/√(a^2 + b^2 + c^2), where (a, b, c) are the coefficients of the plane equation and (x, y, z) are the coordinates of the point.

For the first part of the question, the distance from the point (-1, 3, -5) to the plane 4x – 4y + 3z = -2 can be found by plugging in the values into the formula:
d = |(4)(-1) + (-4)(3) + (3)(-5) + (-2)|/√(4^2 + (-4)^2 + 3^2)
d = |-4 - 12 - 15 - 2|/√(16 + 16 + 9)
d = |-33|/√41
d = 33/√41

For the second part of the question, an equation of the plane through the point (-1, -2, 2) and perpendicular to the vector (5, -1, -2) can be found by using the formula ax + by + cz = d, where (a, b, c) are the components of the vector and (x, y, z) are the coordinates of the point. Plugging in the values gives:
(5)(x - (-1)) + (-1)(y - (-2)) + (-2)(z - 2) = 0
5x + 5 - y - 2 - 2z + 4 = 0
5x - y - 2z = -7

Therefore, the equation of the plane is 5x - y - 2z = -7.

65. Find cos tetha, given that sin tetha = 3/5 and tetha is in quadrant II.

We can use the identity cos^2 tetha + sin^2 tetha = 1 to find cos tetha.

cos^2 tetha = 1 - sin^2 tetha

cos^2 tetha = 1 - (3/5)^2

cos^2 tetha = 1 - 9/25

cos^2 tetha = 16/25

cos tetha = ±√(16/25)

cos tetha = ±4/5

Since tetha is in quadrant II, cos tetha is negative. So, cos tetha = -4/5.

66. Find sin tetha, given that cos tetha = 4/5 and tetha is in quadrant IV.

We can use the same identity to find sin tetha.

sin^2 tetha = 1 - cos^2 tetha

sin^2 tetha = 1 - (4/5)^2

sin^2 tetha = 1 - 16/25

sin^2 tetha = 9/25

sin tetha = ±√(9/25)

sin tetha = ±3/5

Since tetha is in quadrant IV, sin tetha is negative. So, sin tetha = -3/5.

67. Find csc tetha, given that cot tetha = -1/2 and tetha is in quadrant IV.

We can use the identity csc^2 tetha = 1 + cot^2 tetha to find csc tetha.

csc^2 tetha = 1 + (-1/2)^2

csc^2 tetha = 1 + 1/4

csc^2 tetha = 5/4

csc tetha = ±√(5/4)

csc tetha = ±√5/2

Since tetha is in quadrant IV, csc tetha is negative. So, csc tetha = -√5/2.

The initial symbol in the Kiran equation is erroneous, and there are two rates for weights of 1, 2, and 3 ounces. In contrast, the prices for 1, 2, and 3 ounces are incorrectly expressed in the Mai equation.

A contract rate, also known as the coupon rate, stated rate, or nominal rate, is the interest rate that is stipulated in a certain contract.

What went wrong for Kiran?

1. For 1, 2, and 3 ounces, there are two rates: Kiran used the wrong symbols to describe the rates for 1, 2, and 3 ounces. Let's look at an illustration:

0.71  1  ≤  w ≤ 2

0.92  2  ≤ w  ≤ 3

Because in the first line the rate is 0.71 for weights less than or equal to 2, and because this also occurs in the second line, it appears that the rate for 2 pounds here can be both 0.71 and 0.92.

2. He chose the wrong initial symbol since it implies that there is a charge even when the weight is 0, which is not conceivable.

0.50 0 ≤ w ≤ 1 (The rate is 0.50 if the weight is less than or equal to 0)

What is Mai's error?

1. Similar to Kiran, she did not express the rate and the pounds. Let's consider one instance:

0.71 1 < w < 2 (The rate is 0.71 if the weight is less than 2; this is false because the rate is 0.71 if the weight is less than or equal to 2)

Answer:

27.5%

Step-by-step explanation:

Given: the percent increase from 40 to 51

Percent change = 51 - 40 |40| × 100% = 11 40 × 100 = 27.5% (increase).

Where: 40 is the old value and 51 is the new value. In this case we have a positive change (increase) of 27.5 percent because the new value is greater than the old value.

Answer:

27.5%

Step-by-step explanation:

To calculate the percent change from 40 to 51, we can use the following formula:

Percent Change = (New Value - Old Value) / Old Value x 100%

In this case, the old value is 40, and the new value is 51.

So, plugging these values into the formula, we get:

Percent Change = (51 - 40) / 40 x 100%

Percent Change = 11 / 40 x 100%

Percent Change = 0.275 x 100%

Percent Change = 27.5%

Therefore, the percent change from 40 to 51 is 27.5%.

The rewritten rational expression with the indicated denominator of  (6x^2) is (10x) / (6x^2). This is because when we multiply both the numerator and denominator of a rational expression by the same quantity, the value of the expression remains the same.

In this case, by multiplying the numerator and denominator of the original expression (5) / (2x) by 5, we get (10x) / (6x^2). We multiplied both the numerator and denominator by 5 because the denominator of the target expression (6x^2) is twice the denominator of the original expression (2x).

This means that the numerator of the target expression should be double the numerator of the original expression. Hence, by multiplying the numerator and denominator of the original expression by 5, we get the target expression.

Infinitely Many Solutions

Step-by-step explanation:

We can start by simplifying both sides of the equation:

2(12-w) = -2(w-17)-10

Expanding the brackets:

24 - 2w = -2w + 34 - 10

Simplifying:

24 - 2w = -2w + 24

At this point, we can see that both sides of the equation are equivalent, so we can conclude that the equation is an identity and has infinitely many solutions. Any value of w will satisfy the equation.

To find the distance between two complex numbers, we use the formula:

|z2 - z1| = sqrt((Re(z2) - Re(z1))^2 + (Im(z2) - Im(z1))^2)

where Re(z) is the real part of z and Im(z) is the imaginary part of z.

Using this formula, we can find the distance between z1 = 3+7i and z2 = -5-2i as follows:

Re(z1) = 3, Im(z1) = 7

Re(z2) = -5, Im(z2) = -2

|z2 - z1| = sqrt((-5 - 3)^2 + (-2 - 7)^2)

= sqrt((-8)^2 + (-9)^2)

= sqrt(64 + 81)

= sqrt(145)

m = (0 - 6) / (4 - 1) = -2

Luego, utilizamos la fórmula punto-pendiente de la recta:

y - y1 = m(x - x1)

y - 6 = -2(x - 1)

y - 6 = -2x + 2

y = -2x + 8

Por lo tanto, la ecuación punto-pendiente de la recta que pasa por los puntos P1 (1,6) y P2 (4,0) es y = -2x + 8.

Step-by-step explanation:

The simplest form is (x+4)/(x-5). Restrictions on the variable are that x ≠ 5  and x≠-4.

The given expression is (x^(2)+8x+16)/(x^(2)-x-20). In order to simplify this expression, we need to factor the numerator and denominator and then cancel out any common factors.

The numerator can be factored as (x+4)(x+4) and the denominator can be factored as (x-5)(x+4).

So the expression becomes:

(x+4)(x+4)/(x-5)(x+4)

Now we can cancel out the common factor of (x+4):

(x+4)/(x-5)

Therefore, the simplest form of the expression is (x+4)/(x-5).

The restrictions on the variable are that x cannot be equal to 5 or -4, because these values would make the denominator equal to zero and the expression would be undefined.

So the final answer is (x+4)/(x-5) with restrictions x≠5 and x≠-4.

A sunscreen with SPF 15 blocks 93.33% of the sun's UV rays. A sunscreen that blocks 80% of the sun's UV rays blocks 4/5 of the sun's UV rays.The SPF for the sunscreen in part (b) is 5. The sunscreen with SPF 30 blocks 96.67% of the sun's UV rays.

a) To find the percentage of UV rays that a sunscreen with SPF 15 blocks, we can simply divide 14 by 15 and then multiply by 100 to get the percentage:

14/15 * 100 = 93.33%

So a sunscreen with SPF 15 blocks 93.33% of the sun's UV rays.

b) If a sunscreen blocks 80% of the sun's UV rays, we can write this as a fraction by simply dividing 80 by 100:

80/100 = 4/5

So a sunscreen that blocks 80% of the sun's UV rays blocks 4/5 of the sun's UV rays.

c) To find the SPF for the sunscreen in part (b), we can use the formula:

SPF = 1 / (1 - fraction of UV rays blocked)

Plugging in the fraction of UV rays blocked from part (b), we get:

SPF = 1 / (1 - 4/5) = 1 / (1/5) = 5

So the SPF for the sunscreen in part (b) is 5.

d) To determine if the claim on Carol's sunscreen is true, we can use the formula:

fraction of UV rays blocked = 1 - (1 / SPF)

Plugging in the SPF from the label, we get:

fraction of UV rays blocked = 1 - (1 / 30) = 29/30

Converting this fraction to a percentage, we get:

29/30 * 100 = 96.67%

So the sunscreen with SPF 30 blocks 96.67% of the sun's UV rays. This is close to the claim of 97%, but not exactly the same. Therefore, the claim is not completely accurate, but it is close.

The number of weeks it will take Isla to complete her assignments is 2.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Number of assignments=27

Time needed by isla=2.5 hrs

hour limit per day=5

Now,

To find out how many hours Isla will spend on her English assignments, we can multiply the number of assignments by the time it takes her to complete each assignment:

27 assignments * 2.5 hours per assignment = 67.5 hours

So Isla will spend a total of 67.5 hours on her English assignments.

To find out how many days it will take Isla to complete her assignments, we need to divide the total number of hours by the number of hours she can work per day:

67.5 hours / 5 hours per day = 13.5 days

Since Isla cannot complete a fraction of a day, she will need to round up to 14 days. So it will take Isla 14 days to complete her assignments.

To find out how many weeks it will take Isla to complete her assignments, we need to divide the total number of days by the number of days per week. Assuming a standard 7-day week, we have:

14 days / 7 days per week = 2 weeks

The revenue function in dollars from the sale of x campers is given by:

R(x) = 66,000x + 46,000(10+x)^(-1) - 8000

We can simplify this function as follows:

R(x) = 66,000x + 46,000/(10+x) - 8000

= 66,000x + 4600/(1+x/10) - 8000

To find the x-value that maximizes revenue, we need to find the critical points of the function R(x) and then determine whether each critical point corresponds to a local maximum, local minimum, or neither.

Taking the derivative of R(x) with respect to x, we get:

R'(x) = 66,000 - 4600/(1+x/10)^2

Setting R'(x) equal to zero, we get:

66,000 - 4600/(1+x/10)^2 = 0

Multiplying both sides by (1+x/10)^2, we get:

66,000(1+x/10)^2 - 4600 = 0

Expanding and simplifying, we get:

(x+10)^2 = 44/3

Taking the square root of both sides, we get:

x+10 = ±(2*sqrt(11))/3

Subtracting 10 from both sides, we get:

x = -10 ± (2*sqrt(11))/3

So the critical points of R(x) are:

x = -10 + (2sqrt(11))/3 and x = -10 - (2sqrt(11))/3

To determine whether each critical point corresponds to a local maximum, local minimum, or neither, we can use the second derivative test. Taking the second derivative of R(x), we get:

R''(x) = 9200/(1+x/10)^3

At the critical point x = -10 + (2*sqrt(11))/3, we have:

R''(-10 + (2sqrt(11))/3) = 9200/(1+(-10+(2sqrt(11))/3)/10)^3

= 9200/(1+2*sqrt(11)/30)^3

≈ -318.68

Since R''(-10 + (2sqrt(11))/3) is negative, the critical point x = -10 + (2sqrt(11))/3 corresponds to a local maximum of R(x).

Similarly, at the critical point x = -10 - (2*sqrt(11))/3, we have:

R''(-10 - (2sqrt(11))/3) = 9200/(1+(-10-(2sqrt(11))/3)/10)^3

= 9200/(1-2*sqrt(11)/30)^3

≈ 318.68

Since R''(-10 - (2sqrt(11))/3) is positive, the critical point x = -10 - (2sqrt(11))/3 corresponds to a local minimum of R(x).

Therefore, the x-value that maximizes revenue is x = -10 + (2*sqrt(11))/3, and the maximum revenue is:

R(-10 + (2sqrt(11))/3) = 66,000(-10 + (2sqrt(11))/3) + 46,000/(10-10+(2*sqrt(11))/3) - 8000

≈ $630,463.17

Answer:

1= b to the second power, 2=a to the second power, 3=b to the fourth power, 4=a to the fourth

Step-by-step explanation: your welcome

Answer: 2)b^2+a^2

Step-by-step explanation:

x and y would have to be the same value since y(sin) and x(cos) of x and y on the unit circle is the same meaning it's the same point. Thus, cos(x-y) = cos(0) = 1. b^2+a^2=cos^2(x)+sin^2(x)= 1.
