Answer:1.33
Step-by-step explanation:
Byron spent $1.38 more than Cassandra on other groceries, as we subtracted Cassandra's spending ($11.50) from Byron's ($12.88) to determine the difference.
The question asks us to determine how much more money Byron spent compared to Cassandra on their grocery shopping. To find this out, we need to compare the total amount of money each person spent. We have the cost of other groceries for each person, but the cost of yogurt is not given. To solve this problem, we just need to compare the cost of other groceries since that is the only information provided.
Byron spent $12.88 on other groceries.
Cassandra spent $11.50 on other groceries.
To find out how much more Byron spent, we subtract Cassandra's total from Byron's total:
$12.88 - $11.50 = $1.38
Therefore, Byron spent $1.38 more than Cassandra on other groceries.
What is the value of k?
Please answer ASAP, Thank you :)
Answer:
k = 10
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ZYM is an exterior angle of the triangle and
∠'s YZX and ZXY are the 2 opposite interior angles, hence
4k + 5 + 6k + 10 = 115
10k + 15 = 115 ( subtract 15 from both sides )
10k = 100 ( divide both sides by 10 )
k = 10
Answer:
k=10
Step-by-step explanation:
∠ZYX= 180-115= 65 these are supplementary angles adding up to 180°.
The interior angles in the triangle should add up to 180°
Adding the values and then equating to 180° we get the following equation.
65+(4k+5)+(6k+10)=180°
simplifying we get: 80+10k=180
10k=180-80
10k=100
k=10

arc length = 7.5π
Step-by-step explanation:
It is given a circle with central angle ADC = 45° and radius = 30 cm
To find the length of arc ABC
From the figure we can see that the central angle of arc ABC = 45°
Therefore the arc length = (45/360) * Circumference
To find the circumference
Circumference = 2πr = 2 * π * 30 = 60π
To find the arc length
Arc ABC = (45/360) * 60π= 7.5π
Therefore arc length = 7.5π
The correct answer is option 3

The function k(x) = (g x h)(x) is graphed below, where g is an exponential function and h is a linear function. If h(x) = x + 1, which option below give the formula for g? h(x) = 2x h(x) = –2x h(x) = –2–x h(x) = 2–x
Answer:
The graph of your question is attached in the picture below.
g(x) = 2^(-x)
Step-by-step explanation:
First of all, we use a graphing tool to plot each of the equations.
If we multiply in the plotter each graph, we can easily see which is the correct option.
h(x) =x+1
g(x) = 2^-x
Answer:
h(x)=-2^-x
Step-by-step explanation:
True or False. You have to flip the inequality symbol in this problem:
-3x < 15
True
False
You can multiply both sides of an inequality by the same, nonzero number, but if this number is negative, you have to flip the sign.
In this case, in order to solve for x, you have to divide by -3 (i.e. multiply by -1/3), so yes, you must switch the sign:
[tex]-3x<15 \implies x>-5[/tex]
Alternatively, you may add 3x to both sides:
[tex]0<3x+15[/tex]
Subtract 15 from both sides:
[tex]3x>15[/tex]
And divide both sides by 3:
[tex]x>5[/tex]
The sign switch here was hidden behind the fact that we switched the two sides of the inequality

(f(x) = 0.5x2 - 2) + (g(x) = 8x3 + 2)
Answer:
Final answer is [tex]f(x)+g(x)=0.5x^2+8x^3[/tex]
Step-by-step explanation:
Given functions are [tex]f\left(x\right)=0.5x^2-2[/tex] and [tex]g(x)=8x^3+2[/tex]
Now we need to add both functions:
[tex]f(x)+g(x)[/tex]
[tex]=(0.5x^2-2)+(8x^3+2)[/tex]
[tex]=0.5x^2-2+8x^3+2[/tex]
[tex]=0.5x^2+8x^3-2+2[/tex]
combine like terms -2 and +2
[tex]=0.5x^2+8x^3[/tex]
Hence final answer is [tex]f(x)+g(x)=0.5x^2+8x^3[/tex]
Answer:
[tex] f ( x ) + g ( x ) = 8 x^3 + 0.5 x ^2 [/tex]
Step-by-step explanation:
We are given the following two functions and we are to find their sum:
[tex] f ( x ) = 0.5 x ^ 2 - 2 [/tex]
[tex] g ( x ) = 8 x ^ 3 + 2 [/tex]
Adding the two given functions to get:
[tex] f ( x ) + g ( x ) = 0.5 x ^ 2 - 2 + 8 x ^ 3 + 2 [/tex]
Rearranging them to solve further:
[tex]f(x)+g(x) =8x^3+0.5x^2+2-2[/tex]
So finally we get:
[tex]f(x)+g(x) =8x^3+0.5x^2[/tex]

Does the rule y=-3*2^x represent a linear or an exponential function?
Answer:
its exponential because the parent function is y=(a)(b)^x
Step-by-step explanation:
Final answer:
The rule y = -3 ∙ 2ˣ defines an exponential function due to the term 2ˣ, where the base 2 is a constant raised to the variable power x, leading to a rapid change in y values as x changes.
Explanation:
The rule y = -3 ∙ 2ˣ represents an exponential function, not a linear function. In a linear function, the variable x is raised to the first power and appears in the form y = mx + b, where m and b are constants, and the graph is a straight line. In contrast, an exponential function is of the form y = a ∙ bˣ, where a and b are constants, and b is the base raised to the power of x.
The presence of the term 2ˣ indicates that as x increases, the value of y changes at an exponential rate. This is characterized by a curve that shows a rapid increase or decrease in value rather than a constant rate of change. Additionally, since the base b (which is 2 in this case) is a positive number other than 1, and it is raised to the power of x, this confirms the exponential nature of the function.

This question is super common sense which probably makes you
want to rethink the simple answer. Very plainly it says: Tuesday the Baker makes a total of 60 muffins. It doesn't tell us what "kind" of muffins they

They are only giving us one number that the Baker bakes on Tuesday and that number is 60
Factor 16w^4+16w^2-140
Find the Greatest Common Factor (GCF)
GCF = 4
Factor out the GCF. (Write the GCF first, then in parenthesis, divide each term by the GCF)
4(16w^4/4 + 16w^2/4 - 140/4)
Simplify each term in parenthesis
4(4w^4 + 4w^2 - 35)
Split the second term in 4w^4 + 4w^2 - 35 into two terms
4(4w^4 + 14w^2 - 10w^2 - 35)
Factor out common terms in the first two terms, then in the last two terms.
4(2w^2(2w^2 + 7) - 5(2w^2 + 7))
Factor out the common term 2w^2 + 7
= 4(2w^2 + 7)(2w^2 - 5)

A mosaic is made from 25 pieces each piece is a parallelogram as shown in the figure what is the total area of the mosaic?
Answer:
Step-by-step explanation:
Unless there is something special about this, the answer is 25 times the area of 1 parallogram.
Area of 1 parallelogram = Base * Height
Base = B = 5.3 cm
Height = H = 3.3 cm
Area = B*H
Area = 5.3 * 3.3
Area = 17.49
There are 25 pieces.
Total Area = 25 * 17.49
Total Area = 437.25 cm^2

Generally speaking, a function can be stretched by multiplying it with the absolute value of a numerical value that is either greater than 1 or less than -1.
Additionally, you should multiply the x-variable with the shrink or stretch factor when compressing (shrinking) or stretching a function horizontally.
Since the numbers 1 and -1 both yield the same output value, it ultimately implies that the graph of the parent function must be a parabola and a quadratic function;
As x decreases from -1, k(x) would increase.
As x increases from 1, k(x) would increase.
Missing information:
Function k has a parent function. The table shows some ordered pairs that belong to k.

There are 4 pennies, 2 nickels, 5 dimes, and 5 quarters in a jar. The probability that a random selected coin is a penny is 1/4. Is this experimental or theoretical probability
Answer:
Theoretical
Step-by-step explanation:
There are 4 pennies out of 16 coins, so the probability is 4/16, which reduces to 1/4. This is based on the beginning situation, not on the results of an experiment, so it is the theoretical probability. Theoretically, you have a 1/4 chance of pulling a penny, but that isn't necessarily what will happen.

The vertex form of the equation of
a parabola is y = 2(x +4)^2 - 7.What is the standard form of the equation?
Answer:
The standard form of the equation is y = 2x^2 + 16x + 25
Step-by-step explanation:
To find the standard form, first square the parenthesis.
y = 2(x + 4)^2 - 7
y = 2(x^2 + -8x + 16) - 7
Now distribute the 2
y = 2(x^2 + 8x + 16) - 7
y = 2x^2 + 16x + 32 - 7
Now combine like terms
y = 2x^2 + 16x + 32 - 7
y = 2x^2 + 16x + 25
