About 14 out of 36 or 7 out of 18 because it’s selecting three numbers 12 times and 14 of them are 0s. And 14 out of 36 simplified is 7 out of 18.

Answer:

$151.87

Step-by-step explanation:

The new balance includes the previous balance, plus finance/interests charges, plus the new purchases, minus the payment(s).

So,

Previous balance: $142.55

+ Finance charge: $2.82

+ New purchases: $86.50

= Sub-total: $231.87

- Payment: $80.00

= New Balance: $151.87

Marissa Palmer's new balance after considering her previous balance, finance charge, new purchases, and payment is $151.87.

To calculate Marissa Palmer's new balance on her charge account statement, we need to consider several components: the previous balance, finance charge, new purchases, and the payment she made. We start with her previous balance, add any finance charges, add the cost of new purchases, and then subtract any payments. Here's the step-by-step calculation:

When we do the subtraction ($231.87 - $80.00), we find that her new balance is $151.87.

Answer:

The corresponding point for the function [tex]f(\frac{1}{3}x)[/tex] is

(18, -3)

Step-by-step explanation:

By definition if we have a function f(x) and we apply the transformation:

[tex]y = f (hx)[/tex]

Then:

If [tex]0 <h <1[/tex] the graph is stretched horizontally  by a factor [tex]\frac{1}{h}[/tex]

If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]

In this case [tex]h=\frac{1}{3}[/tex]  this is [tex]0 <h <1[/tex] then the graph is stretched horizontally  by a factor [tex]\frac{1}{\frac{1}{3}}=3[/tex]

Therefore the point (6, -3) that belongs to f(x), in the transformed function will be (3*6, -3) This is (18, -3)

Answer:

15. Radius

16. CF is parallel to AH , Option C

17. Option A , AB congruent to ST

Step-by-step explanation:

15.  The line joining the center and any point on the circumference of a circle is the radius if the circle. Here Center is O and is being joined by B which lies on circumference hence OB makes a radius.

16. In  a cuboid , all the heights are parallel to each other. Hence CF ║AH ║ BE ║ DG

Hence the right answer is option C

17. If we observe the two quadrilaterals we see that

A overlaps to S , B to T , C to U and D to V

Hence

AB is congruent to ST

Answer:

[-1, -6]

Step-by-step explanation:

Since both coefficients next to your y's are identical use the Elimination Method by multiplying one of the equations by -1 to form additive inverses, meaning they result in 0:

-1[{2x - 3y = 16}]↷

{5x - 3y = 13}

{-2x + 3y = -16

{5x - 3y = 13

----------------

3x = -3 [Divide by 3]

x = -1

y = -6 [plug in "-1" back into both equations to confirm their authenticities]

[tex](b ^ 5) ^ 2 = b ^ {5 * 2} = b ^ {10}[/tex]

ANswer:

[tex]b^{10}[/tex]

Option A

the first choice is correct

The maximum area of the rectangle will be 242 square ft. The expression for a in terms of x will be 44 - 2x. Then the correct option is C.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

If the a, b, and x are 44 ft. Then the expression for a in terms of x will be

We know that b = x

Then we have

a + b + x = 44

   a + 2x = 44

           a = 44 - 2x

Then the area opf the rectangle will be

Area = (44 - 2x)x

Area = 44x - 2x²

For maximum area the value of  x will be 11. Then we have

Area = 44 × 11 - 2 × 11²

Area = 242 square ft

Answer:

[tex]\boxed{\text{3.74 m}}[/tex]

Step-by-step explanation:

This is equivalent to finding the equation of a parabola from three points.

Let's call the ground-level points (-3.5, 0) and (3.5, 0).

The axis of symmetry will be the y-axis, so the vertex is at (0, 7).

Part 1. Find the equation of the parabola

The vertex form of the equation for a parabola is

y = a(x - h)² + k

where (h, k) is the vertex of the parabola.

If the vertex is at (0, 7),  

h = 0 and k = 7

The equation is

y = ax² + 7

Insert the point (0, -3.5)

0 = a(0 + 3.5)² + 7

0 = a(3.5)² + 7

0 = 12.25a + 7

-7 = 12.25a

a = -0.5714

The equation in vertex form is

y = -0.5714x² + 7

Part 2. Calculate the width when y = 5

 5 = -0.5714x² + 7

-2 = -0.5714x²

x² = 2/0.5714

x² = 3.5

x = ±√3.5 = ±1.87  

So, on the graph, the coordinates of the truck at ground level are x = -1.87 and x = +1.87.

The maximum width of the load is 1.87 – (-1.87) =[tex]\boxed{\textbf{3.74 m}}[/tex]

3 2/3 the answer because....

11 cant fit into three so, if you divide 11%3 = 3 2/3 now let’s see, how much times can you multiply 3 into 11 only 3 times 3,6 and 9 (things) then the 2/3 is there because, if add 1 more 0.1 you get 12/3 but it’s not it’s 2/3 of the value

11/3 is already in its simplest fractional form as there are no common factors between 11 and 3. However, it can be expressed as a mixed number, which is 3 2/3 in this case.

To simplify 11/3, you must first understand what it means to simplify a fraction. Simplifying a fraction means to reduce it to its simplest form, or to a form that can no longer be reduced. However, 11/3 is a fraction that cannot be simplified any further as there are no common factors between the numerator (11) and the denominator (3). It is in its simplest form. But, if we're looking to express this as a mixed number, we would divide 11 by 3. The result is 3 with a remainder of 2. Hence, 11/3 can be expressed as the mixed number 3 2/3

Answer:

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

The red line is g(x)

Step-by-step explanation:

* To solve this problem you must to know some fact about

  transformation

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

- A vertical stretching is the stretching of the graph away from

 the x-axis

• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically

 stretched by multiplying each of its y-coordinates by k.

- A vertical compression is the squeezing of the graph toward

 the x-axis.

• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed

 by multiplying each of its y-coordinates by k.

• if k should be negative, the vertical stretch or compress is

 followed by a reflection across the x-axis.  

* Now lets solve the problem

- g(x) = -1/2f(x + 2)

# x + 2 ⇒ means the graph moved 2 units to the left

# -1/2 ⇒ means the graph has vertical compressed followed

 by a reflection across the x-axis, then multiply

 each y-coordinate by -1/2

- The graph of f(x) intersects x-axis at point (3 , 0)

∴ The point will be (1 , 0) on g(x)

- The graph of f(x) intersects y-axis at point (0 , -6)

∴ The point will be (-2 , 3) on g(x)

* Look to the graph

# The red line is g(x)

# The blue line is f(x)

- To check your answer

# The equation of f(x) is f(x) = 2x - 6

∵ g(x) = -1/2f(x + 2)

∴ g(x) = -1/2[2(x + 2) - 6] = -1/2[2x + 4 - 6] = -1/2[2x - 2] = -x + 1

* g(x) intersect x-axis at point (1 , 0) and y-axis at point (0 , 1)
