Answer:
Domain = R
Range = (-∞, 4)
Hor. asymp = y=4
Y intercept: f(0) = (0,2)
end behaviour:
x → -∞: f(x) → 4
x→ ∞: f(x) → -∞
Step-by-step explanation:
For the domain, it is R because e^x works for all values of x
For the range, y will never be above 4.
The hor. asymptote is found via [tex]\lim_{x \to -\infty} f(x)[/tex] there the e term will be zero, so what is left is y=4.
Y intercept, fill in f(0)
end behaviour: for small x, y goes to the asymptote, for large x, y goes to minus infinity.
Final answer:
Explained the Domain, Range, Horizontal Asymptote, Y-Intercept, and End Behavior of f(x) = -2e^x + 4
Explanation:
Domain and Range:
Domain: All Real Numbers
Range: f(x) ≤ 4
Horizontal Asymptote:
Horizontal Asymptote: y = 4
Y-Intercept:
Y-Intercept: (0, 2)
End Behavior:
End Behavior: As x → ∞, f(x) → 4; As x → -∞, f(x) → -∞

(The 4 is the people that study French)
(The 11 is the people that don't study French. This includes the people that aren't studying a language at all)
Step-by-step explanation:
[tex]\frac{2}{5}[/tex] of the [tex]\frac{2}{3}[/tex] that study a language, is studying French.
[tex]\frac{2}{5}[/tex]*[tex]\frac{2}{3}[/tex]=[tex]\frac{4}{15}[/tex] so [tex]\frac{4}{15}[/tex] of the entire school studies French. that means [tex]\frac{11}{15}[/tex] of the school doesn't study French. In a ratio, it'd be 4 : 11 ratio

If y = 3x squared + 4 find the value of y when x = 2
Answer:
The value of y is 16.
Step-by-step explanation:
You have to substitute x = 2 into the equation :
[tex]y = {3x}^{2} + 4[/tex]
Let x = 2,
[tex]y = 3( {2)}^{2} + 4[/tex]
[tex]y = 3(4) + 4[/tex]
[tex]y = 12 + 4[/tex]
[tex]y = 16[/tex]
Answer:
y = 16
Step-by-step explanation:
Let's solve your equation together
3x^2 + 4
We have been given that x = 2
So first we must replace x by 2.
y = 3(2)^2 + 4
Now we solve the equation
2^2 = 4
y = 3(4) + 4
3 * 4 = 12
y = 12 + 4
12 + 4 = 16
y = 16

1/4 inch cubes were used to fill a prism. The dimensions of the prism are 1.5 inches x 1 inch x 3.75 inches. How many 1/4 inch cubes can fit into the prism?
A) 22.5
B) 360
C) 720
D) 180
Answer:
B) 360 cubes
Step-by-step explanation:
We can start by finding how many cubes fit into the length of the prism (1.5 in) which is 6 cubes for 1.5 in/ 0.25 in = 6.
Then we can find the number of cubes to fit the width of the prism (1 in) which is 4 cubes for 1 in/ 0.25 in = 4.
Finally we find that 15 cubes fit the height (3.75 in) for 3.75 in/ 0.25 in = 15 cubes.
Multiplying the together, we get 6*4*15=360 or B

In the right triangle shown, mZA = 30° and BC = 6/2.
How long is AC?
Answer:
x = 18
Step-by-step explanation:
Since 30-60-90 triangles have a side ratio of y : y√3 : 2y.
Since 2y, here, is 12√3, then y is 6√3.
This means that the side x, is 6√3 * √3, which is:
x = 6√3 * √3
= 6 * 3
x = 18

what is augmented matrix ?
An augmented matrix is a way of representing a system of linear equations in a matrix form. It consists of a rectangular array of numbers, where the coefficients of the variables in each equation are placed in one part of the matrix
In the given question,
To write the system of equations corresponding to the augmented matrix, we need to represent the coefficients and constants of the variables.
The given augmented matrix corresponds to the following system of linear equations:
-8x - 2y - 1z = -15

The mean length of 6 childrens' big finger is 8.3cm. The mean length of 5 adults' big finger is 17.7cm. What is the mean length (rounded to 2 DP) of these 11 people's big finger?
Answer:
The mean for the whole group is 12.57 cm
Step-by-step explanation:
The mean of the length of each group's finger is given by the following formula:
mean = (sum of lengths from each finger)/number of people
Therefore for the first group:
8.3 = (sum1)/6
sum1 = 8.3*6 = 49.8
For the second group:
17.7 = sum2/5
sum2 = 17.7*5 = 88.5
Therefore the mean from the whole group is:
mean = (sum1 + sum2)/11 = (49.8 + 88.5)/11 = 12.57 cm

Kali is single and earns $45,800 per year. What is her annual federal withholding?
The table would continue this pattern up to 1,800 hours
The question involves creating a table that displays the effect of earned income on government support and total income for a single mother, named Susan. Given that Susan earns $8 per hour and loses $1 in government benefits for every $1 earned, we calculate the impact of different work hours on her total income. The table will illustrate the intersection of labor and welfare economics, showing the disincentive to work that some assistance programs might create due to the reduction in benefits as earned income rises.
To provide an example for Susan's situation: If she works 500 hours at $8 per hour, her earnings from work would be $4,000. With government benefits reducing dollar for dollar, Susan's new benefits would be $16,000 - $4,000, which equals $12,000. So, her total income would be her earnings ($4,000) plus the adjusted government benefits ($12,000), totaling $16,000. The table would continue this pattern up to 1,800 hours

Answer:
i think true but im not sure
Step-by-step explanation:
Bonnie had 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills in her pocket. She randomly took 3 bills from her pocket. How much money could Bonnie have taken from her pocket?
Answer:
There are 5 different outcomes, $30, $21, $20, $16 and $11.
Step-by-step explanation:
Bonnie has a total of 6 bills in her pocket. If she takes 3 random bills, this means that there are 20 different possibilities but the five dollar bills and ten dollar bills are not indistinctive so the number is not 20 for this example.
She can take the 1 dollar bill and the two 5 dollar bills which would make 11 dollars.
She can take the 1 dollar bill and the two 10 dollar bills which would make 21 dollars.
She can take the 1 dollar bill, one 5 dollar bill and one 10 dollar bills which would make 16 dollars.
She can take two 5 dollar bills and one 10 dollar bill which would make 20 dollars.
She can take two 10 dollar bills and one 5 dollar bill which would make 30 dollars.
So there are 5 different outcomes, $30, $21, $20, $16 and $11.
I hope this answer helps.
Final answer:
Bonnie could have possibly drawn $11, $21, $20, or $25 by selecting any 3 bills out of 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Explanation:
The question concerns the amount of money Bonnie could have taken from her pocket after randomly selecting 3 bills. To answer this, let's consider her initial set of bills: 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Here are the possible combinations of 3 bills she could draw:
1 one-dollar bill and 2 five-dollar bills: $1 + $5 + $5 = $11
1 one-dollar bill and 2 ten-dollar bills: $1 + $10 + $10 = $21
2 five-dollar bills and 1 ten-dollar bill: $5 + $5 + $10 = $20
1 five-dollar bill and 2 ten-dollar bills: $5 + $10 + $10 = $25
Therefore, the amounts of money Bonnie could have drawn are $11, $21, $20, and $25.
Sine and cosine are both negative in which quadrant?
Answer:
quad 3
Step-by-step explanation:
Use "all students take calculas"
quad 1: a=all positive
quad 2: s=only sine positive, tan and cos negative
quad 3: t=only tan positive, cos and sin negative
quad 4: c=only cos positive, tan and sin negative
In trigonometry, both sine and cosine are negative in the third quadrant of the coordinate plane, as both the x and y coordinates are negative in this quadrant.
Explanation:In the context of trigonometry, on the coordinate plane, sine and cosine are both negative in the third quadrant. The sine function represents the y-coordinate and the cosine function represents the x-coordinate of a point on the unit circle. Hence, in the third quadrant, where both x and y are negative, both sine and cosine are negative as well. This is a basic idea from trigonometry and is commonly referred to as the rule 'All Students Take Calculus', which helps to remember the sign of sine, cosine and tangent in each quadrant. A- all (Quadrant I, all are positive), S - Sine (Quadrant II, only sine is positive), T - Tangent (Quadrant III, only tangent is positive), C - Cosine (Quadrant IV, only cosine is positive). Therefore in the III quadrant, both sine and cosine are negative as only tangent (ratio of sine to cosine) is positive.
