Answer: $99
Step-by-step explanation:
Yvette's estimated cost for buying 9.3 yards of velvet fabric at $11.49 per yard is approximately $106.86. This is calculated by multiplying the price per yard with the number of yards. An initial rough estimate of $103.50 was also considered before doing a precise calculation.
To calculate the estimated cost of the velvet fabric Yvette buys, you need to multiply the price per yard by the number of yards:
Price per yard = $11.49
Number of yards = 9.3
Estimated cost = $11.49 × 9.3
Let's break it down step-by-step:
First, estimate the two numbers. $11.49 is close to $11.50, and 9.3 is close to 9. Then, multiply: 11.50 × 9 = $103.50.Now calculate more precisely: 11.49 × 9.3 = 106.857 but rounded to two decimal points, it's $106.86.So, Yvette's estimated cost of the fabric is approximately $106.86.

If A(0, 0), B(3, 3), C(9, 3), and D(6, 0) are the vertices of a quadrilateral, do the points form a parallelogram? Justify your answer.
A. Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals 1, and AB = DC = square root of 18.
B. Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals −1, and AD = CD = 3 units.
C. Yes, it is a parallelogram because the midpoint of the diagonals of segment AC and segment BD is (4.4, 1.5).
D. No, it is not a parallelogram because the slope of segment AB = 1 and the slope of segment DC = −1.

What are the zeros of f(x) = 4x^2 - 12x + 8 (I need a clear explanation on how to solve it)
The zero of the quadratic function is therefore x = 1. Since both factors give the same zero, we have a repeated zero and f(x) only touches the x-axis at one point, x = 1.
The zeros of the quadratic function f(x) = 4x^2 - 12x + 8 are the values of x that make f(x) = 0. In this function, we can factor by finding two numbers that multiply to give the constant term (8 times 4, the coefficient of x^2) and add to give the coefficient of x (-12). Here, those numbers are -4 and -4, so we rewrite the middle term -12x as -4x - 4x, and factor by grouping:
4x^2 - 4x - 4x + 8 = 0
4x(x - 1) - 4(x - 1) = 0
(4x - 4)(x - 1) = 0
Now we have two factors equal to zero, which gives us two equations to solve:
4x - 4 = 0 or x - 1 = 0
x = 1

For what values of b will F(x) = logb x be an increasing function?
A. b < 0
B. b > 0
C. b < 1
D. b > 1,
Final answer:
The logarithmic function F(x) = logb x is an increasing function when the base b is greater than 1, because the value of logb x increases as x increases for b > 1.(Option D)
Explanation:
The question asks for what values of b will F(x) = logb x be an increasing function. To determine this, we need to understand the behavior of logarithmic functions based on their base value (b). A logarithmic function is increasing if the base of the logarithm is greater than 1. This is because as x increases, the value of logb x increases when b>1. Conversely, if b<1 (but b>0), the function is decreasing because the power to which b must be raised to produce x decreases as x increases. We also know that the base of a logarithm cannot be negative or zero, as this would not produce a valid logarithmic function.
Therefore, the correct answer is D. b > 1, where the logarithmic function F(x) = logb x is an increasing function.
Can someone please help? In the circle at right, AZB is a(n): (A) minor arc, (B) central angle, (C) major arc, (D) arcezoid, or (E). None of these? Thanks
In this question it has been clearly indicated that AZB is to be taken as an arc. This is because there is the arc symbol on top of AZB. Thus, we have [tex] \overarc{AZB} [/tex] and we need to answer what does the arc [tex] \overarc{AZB} [/tex] represent.
As we can see from the diagram, by visual inspection, that AZ is the chord which is lesser than the diameter and AZB is the segment on that lesser side of the circle. Therefore, the arc [tex] \overarc{AZB} [/tex] must be the minor arc.
Therefore, Option A, minor arc is the correct answer.

Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y=3.5x+4; a(...; 5), b(10; ...)
A(2/7:5)
B(10:39)
The slope is 7/2.
The slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation of line is y=3.5x+4
When we compare this with slope intercept form y=mx+b.
slope m=3.5
We need to find the value of x when y is 5
5=3.5x+4
1=3.5x
Divide both sides by 3.5
x=0.28
So a coordinates are (0.28, 5)
Now let us find y value when x is 10
y=3.5(10)+4
y=39
So b coordinates are (0.28, 39)
Hence, the slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)

what is the sum of the arithmetic series 18 t=1 (3t-4)
a. 234
b. 441
c. 25.5
d. 49
The given arithmetic series is
[tex] \sum_{t=1}^{18} (3t-4) [/tex]
When t =1, we will get the first term,a, which is
[tex] 3(1)-4 =3-4=-1 [/tex]
When t =18, we will get the last term,l , which is
[tex] 3(18)-4 = 50 [/tex]
Now we use the formula of sum of n terms which is
[tex] S = \frac{t}{2} (a+l) [/tex]
Substituting the values of t,a and l, we will get
[tex] S = \frac{18}{2} (-1+50) = 9*49 =441 [/tex]
Consider the arithmetic series [tex] _{t=1}\Sigma^{t=18} (3t-4) [/tex]
Let t=1 in the given series, we get
first term = [tex] a_{1} [/tex] = 3-4 = -1.
Let t=2 in the given series, we get
second term = [tex] a_{2} [/tex] = [tex] (3 \times 2)-4 = 2 [/tex]
Let t=3 in the given series, we get
third term = [tex] a_{3} = (3 \times 3)-4=5 [/tex]
Now, let t=18 in the given series, we get
last term = l = [tex] l = (3 \times 18)-4 = 50 [/tex]
We get the series as
-1, 2, 5,..... 50
Sum = [tex] \frac{n}{2}(a+l) [/tex]
= [tex] \frac{18}{2}(-1+50) [/tex]
= [tex] = 9 \times 49 [/tex]
= 441
Therefore, the sum of the given arithmetic series is 441.
