4. Write an equation for the line that is parallel to the given line and that passes
through the given point.
y = 5/2x-10;(-6,-29)

=====================================================

Explanation:

To factor this, we need to find two numbers that

Through trial and error, you would find that the two numbers are -2 and -7

-2*(-7) = 14

-2 + (-7) = -9

So that's why the given trinomial factors to (y-2)(y-7)

You can use the FOIL rule to go from (y-2)(y-7) back to y^2-9y+14 again.

Given:

Consider the below figure attached with this question.

To find:

The function that has the domain [tex]x\geq -11[/tex].

Solution:

We know that, a radical function is defined for only non negative radicand.

In option A, the function is defined if

[tex]x+11\geq 0[/tex]

[tex]x\geq -11[/tex]

The domain of this function is [tex]x\geq -11[/tex]. So, option A is correct.

In option B, the function is defined if

[tex]x-11\geq 0[/tex]

[tex]x\geq 11[/tex]

The domain of this function is [tex]x\geq 11[/tex]. So, option B is incorrect.

In option C and D, the function is defined if

[tex]x+5\geq 0[/tex]

[tex]x\geq -5[/tex]

The domains of these function are [tex]x\geq -5[/tex]. So, options C and D are incorrect.

Hence, option A is correct.

Answer:

m = [tex]-\frac{8}{5}[/tex]

Step-by-step explanation:

m = slope

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{1--7}{-6--1}[/tex]

m = [tex]\frac{8}{-5}[/tex]

m = [tex]-\frac{8}{5}[/tex]

Answer: The correct option is A.

Step-by-step explanation:

To calculate the distance between the points, we use the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where,

d= distance

[tex]x_2\text{ and }x_1[/tex] are the coordinates of the points on x-axis

[tex]y_2\text{ and }y_1[/tex] are the coordinates of the points on y-axis

For the given points:

A(-4,3), B(2,5), C(3,2) and D(-3,0)

[tex]x_2=3\\x_1=-3\\y_2=2\\y_1=0[/tex]

Putting values in above equation, we get:

[tex]CD=\sqrt{(3-(-3))^2+(2-0)^2}\\\\d=\sqrt{36+4}=6.32units[/tex]

[tex]x_2=-4\\x_1=-3\\y_2=3\\y_1=0[/tex]

Putting values in above equation, we get:

[tex]AD=\sqrt{(-4-(-3))^2+(-3-0)^2}\\\\d=\sqrt{1+9}=3.16units[/tex]

To calculate the area of a reactangle, we use the equation:

[tex]Area=l\times b[/tex]         ....(1)

where,

l = length of the rectangle = CD = 6.32 units

b = breadth of the rectangle = AD = 3.16 units

Putting values in equation 1, we get:

[tex]Area=6.32\times 3.16\\\\Area=20.0 \text{ square units}[/tex]

Hence, the correct option is A.

The answer is A.

Answer:

<ABC = 27

< BAC = 126

Step-by-step explanation:

<C = <B since it is an isosceles triangle.  We know this since AC - AB

<C = 27 so <ABC = 27

The sum of the angles of a triangle = 180

A + B+ C = 180

A + 27+27 = 180

A + 54 =180

A = 180-54

A =126

< BAC = 126

Answer:

2a. 1/4

2b. 2/8

2c. yes, 1/4 = 2/8 because

2 / 8 = 2 ÷ 2 / 8 ÷ 2 = 1 / 4.

2d. the total number of parts doubled in the denominator, the number of parts represented in the numerator doubled as well.

The operations of division and multiplication are made proportionally to the numerator and denominator.

Given:

The table and the relative frequency histogram show the distribution of the number of tails and three coins are tossed.

To find:

The probability [tex]P(T=3)[/tex].

Solution:

In the given table T represents the number of tails.

From the given table it is clear that the value of probability is [tex]\dfrac{1}{8}[/tex] and [tex]T=3[/tex]. So,

[tex]P(T=3)=\dfrac{1}{8}[/tex]

Therefore, the probability [tex]P(T=3)[/tex] is equal to [tex]\dfrac{1}{8}[/tex].

Answer:

(a)[tex]e^{-0.000428 t}[/tex]

Step-by-step explanation:

We are given that

Half life of radium-226=1620 yr

The quantity left Q(t) after t years is given by

[tex]Q(t)=(\frac{1}{2})^{\frac{t}{1620}}[/tex]

a. We have to convert the given function into an exponential function using base e.

[tex]Q(t)=(\frac{1}{2})^{\frac{t}{1620}}[/tex]

=[tex]((\frac{1}{2})^t)^{\frac{1}{1620}[/tex]

=[tex]e^{ln(1/2) t/1620}[/tex]

[tex]=e^({\frac{ln(1/2)}{1620}t)[/tex]

=[tex]e^{-0.000428 t}[/tex]

(b)

[tex]Q(0)=e^{-0.000428 \times 0}[/tex]

=1

From original function

Q(0)=1

[tex]Q(1620)=(\frac{1}{2})^{\frac{t}{1620}}[/tex]

[tex]Q(1620)=\frac{1}{2}=0.5[/tex]

From exponential function

[tex]Q(1620)=e^{-0.000428 \times 1620}[/tex]

[tex]=0.499\approx 0.5[/tex]

[tex]Q(3240)=(\frac{1}{2})^{\frac{3240}{1620})=0.25[/tex]

[tex]Q(3240)=e^{-0.000428 \times 3240}[/tex]

Q(3240)=0.249=[tex]\approx 0.25[/tex]

Hence, verified.

Answer:

2.3

Step-by-step explanation:

Step-by-step explanation:

Answer: It decreases on the interval   (-infinity, 3)

This is the same as saying -infinity < x < 3, or simply x < 3

=============================================================

Work Shown:

f(x) = (3−x)^2 + 5

f(x) = (-x+3)^2 + 5

f(x) = (-1(x-3))^2 + 5

f(x) = (-1)^2*(x-3)^2 + 5

f(x) = 1(x-3)^2 + 5

The last equation is in the form y = a(x-h)^2 + k

We have a = 1, h = 3 and k = 5

The vertex is (h,k) = (3,5)

Since 'a' is positive, this means the function decreases on the left and increases on the right (forming a parabola that opens upward). See below.

So the function is decreasing when x < 3, which represents everything to the left of the vertex.

We can expand that out to -infinity < x < 3 which converts to the interval notation (-infinity, 3)

Answer:

the slopes are different, and the y-intercepts are also different

Step-by-step explanation:

We can rewrite the equations given in slope-intercept to easily determine the slope (m) and the y-intercept (b). Slope-intercept equation is y = mx + b

Let's rewrite each equation:

✔️5x + 2y = 2

Subtract 5x from each side

2y = -5x + 2

Divide both sides by 2

y = -5x/2 + 2/2

y = -⁵/2(x) + 1

The slope (m) = -⁵/2

y-intercept (b) = 1

✔️3x - 3y = 18

Subtract 3x from each side

-3y = -3x + 18

Divide both sides by -3

y = -3x/-3 + 18/-3

y = x - 6

Slope (m) = 1

y-intercept (b) = -6

✅Therefore, the slopes are different and the y-intercepts are also different

Answer:

Step-by-step explanation:

Set this up as a ratio of proportions of petrol : oil

[tex]\frac{p}{o}[/tex] and if the ratio of the mix has to be 5p to 2 oil then:

[tex]\frac{p}{o}:\frac{5}{2}[/tex]  We need to find how much oil, x, is needed to mix with 10 liters of petrol. Completing the proportion with that ratio gives us the problem in its entirety:

[tex]\frac{p}{o}:\frac{5}{2}=\frac{10}{x}[/tex] and cross multiply

5x = 20 so

x = 4 liters of oil are needed to mix with 10 liters of petrol.

Answer:

A

Step-by-step explanation:

That is the procedure above

Step-by-step explanation:

I cannot really identify and read the provided answer options.

the solution to the sequence 2, 6, 10, 14, 18, ... is

an = 4×(n-1) + 2

recursive that is

a1 = 2

an = an-1 + 4

please pick the right option in your original problem definition that fits to this solution.

The recursive formula that represents the given sequence is:

[tex]a_n = a_{n-1} + 4[/tex]

An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed constant value to the previous term.

This fixed value is called the common difference, and it is the same for all terms in the sequence.

We have,

The given sequence has a common difference of 4 between its consecutive terms.

To represent this sequence using a recursive formula, we can start with the first term and use the common difference of 4 to find each subsequent term.

Let's assume that the first term of the sequence is a1. Then, we can represent the second term [tex]a_2[/tex] as:

[tex]a_2 = a_1 + 4[/tex]

Similarly, we can represent the third term (a3) as:

[tex]a_3 = a_2 + 4[/tex]

Substituting the value of a2 from the above equation, we get:

[tex]a_3 = (a_1 + 4) + 4 = a_1 + 8[/tex]

We can continue this pattern to find the recursive formula for the nth term of the sequence:

[tex]a_n = a_{n-1} + 4[/tex]

where [tex]a_1[/tex]= 2

Thus,

The recursive formula for the given sequence is:

[tex]a_n = a_{n-1} + 4[/tex]
