Which is a solution of the inequality x + 2 <8?
Group of answer choices
z < 4
z < 6
z = 6
z < 10
answer : z ‹ 6
explanation :
inequality given is x + 2 ‹ 8
take the +2 and move it to the back to 8, so it will be -2.
then you will directly get x ‹ 8 - 2
so the answer will be x ‹ 6.
I'm not sure whether you had the answer choice z is actually x, but if it does the answer is x ‹ 6 and not z ‹ 6

Let f(x)=x2−4 and g(x)=7−x. Perform the composition or operation indicated.
(fg)(8)
Answer:
[tex](f\circ g)(8)=-3[/tex]
Step-by-step explanation:
Composite Function
Given f(x) and g(x) real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
For practical purposes, it can be found by substituting g into f.
The functions are defined as follows:
[tex]f(x)=x^2-4[/tex]
[tex]g(x)=7-x[/tex]
To find [tex](f\circ g)(8)[/tex], we evaluate g in x=8 and then apply the composition formula.
[tex]g(8)=7-8=-1[/tex]
[tex](f\circ g)(8)=f(g(8))[/tex]
[tex](f\circ g)(8)=f(-1)[/tex]
[tex](f\circ g)(8)=(-1)^2-4=1-4[/tex]
[tex]\boxed{(f\circ g)(8)=-3}[/tex]

XYZ’s print publication charges $15 for each of the first four lines of an ad, and $9 for each additional line. Express the cost of an x-line ad, c(x), as a piecewise function.
By using the given information we can infer the domains of the function, and we will see that the piecewise function is:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
How to get the piecewise function?
We know that the print charges $15 for each of the first four lines on an add, and $9 for each additional line.
Then we will have one piece for x between 0 and 4, and another piece for x larger than 4. The function will be:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
Where the y-intercept on the second part is equal to the cost for the first four lines of the add.

Suppose a firm loses $4,000 in its first month, but increases its profit by $575
each month for the first year. Find the firm's total profit or loss in the first
year.
O Loss of $10,050
O Loss of $2,250
O Profit of $2,325
O Profit of $85,950
Answer:
profit of $2325
Step-by-step explanation:
so a loss of $4000 in the first month, with profit of $575 each month. let's say a year have 12 months, first month with loss, the other 11 months with profit. so, $575 x 11 months = $6325. $6325 is the amount for 11 months with $575 profit. take $6325 and minus with $4000 and you will get $2325, which is the profit for the first year.

Answer:
We need to find the circumference, and in order to find the circumference we must know the formula for it.
Formula for circumference of a circle;
a = 2πr
Where π is the pi(3.14 or 22/7), and r is the radius which is half of the diameter.
Since we are given the diameter, we need to find the radius. So 1/2 of the diameter (26 x 1/2) = is 13
Now we just plug in the actual values in the formula:
a = 2πr
a = 2 x 3.14 x 13
a = 18.84 feet
But now, we need to find how many revolutions it would take to get to 500 feet.
So we divide 500 feet by 18.84 feet;
500/18.84 = 26.53, around 27 revolutions.

Using this and the knowledge that 32° F = 0°C and 212°F = 100°C, find an equation that computes Celsius temperature in terms of Fahrenheit temperature; i.e., an equation of the form C = “an expression involving only the variable F.”
c=(f-32)/1.8
Likewise, find an equation that computes Fahrenheit temperature in terms of Celsius temperature; i.e. an equation of the form F = “an expression involving only the variable C.”
f=1.8c+32
(a) How cold was it in Oslo in °F?
(b) What temperature is it the same in °F and °C?
Answer:
(a)
Step-by-step explanation:
The relationship between temperatures measured in Fahrenheit, and in Celsius can be represented using equations.
The equations are: [tex]F = 1.8C + 32[/tex] and [tex]C = \frac{(F - 32)}{1.8}[/tex].The temperature in Oslo is [tex]60.8^oF[/tex].[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]Given that:
[tex](F_1,C_1) = (32,0)[/tex]
[tex](F_2,C_2) = (212,100)[/tex]
First, calculate the slope (m)
[tex]m = \frac{C_2 - C_1}{F_2 - F_1}[/tex]
So we have:
[tex]m = \frac{100 - 0}{212 - 32}[/tex]
[tex]m = \frac{100}{180}[/tex]
[tex]m = \frac{5}{9}[/tex]
So, the equation is calculated using:
[tex]C= m(F - F_1) + C_1[/tex]
So, we have:
[tex]C = \frac 59(F - 32) + 0[/tex]
[tex]C = \frac 59(F - 32)[/tex]
Rewrite as:
[tex]C = \frac{(F - 32)}{9/5}[/tex]
[tex]C = \frac{(F - 32)}{1.8}[/tex]
To solve for F, we multiply both sides by 1.8
[tex]1.8C =F - 32[/tex]
Add 32 to both sides
[tex]F = 1.8C + 32[/tex]
(a) The temperature of Oslo in F
We have:
[tex]C = 16[/tex]
So, we make use of:
[tex]F = 1.8C + 32[/tex]
[tex]F = 1.8 \times 16 + 32[/tex]
[tex]F = 60.8[/tex]
The temperature in Oslo is [tex]60.8^oF[/tex]
(b) When F = C
We have:
[tex]F = 1.8C + 32[/tex]
Substitute F for C
[tex]F = 1.8F +32[/tex]
Collect like terms
[tex]F - 1.8F =32[/tex]
[tex]-0.8F =32[/tex]
Make F the subject
[tex]F = \frac{32}{-0.8}[/tex]
[tex]F = -40[/tex]
Hence,
[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]

y=Cx2
x=Cy2
x2 – y2 = C2
x2 + y2 = C2
Answer:
[tex]y=Cx^2[/tex]
Step-by-step explanation:
Clearly, [tex]\frac{dy}{dx}[/tex] is a function of x, so we can eliminate the second option.
The slope field does not resemble a circle nor hyperbola, so we can eliminate the last two options.
This leaves us with [tex]y=Cx^2[/tex] as our general solution.

So 6 x 4 which is 24
Then, find the square:
Formula: side x side
So 3 x 3 which is 9
Finally subtract the two areas to find the remaining sheet of paper
24 - 9 = 15
Answer:
the remaining sheet of paper is 3cm long and 1 cm wide
Step-by-step explanation:
the length of rectangular sheet is 6cm and when you cut 3 cm from it it remains 3 cm
the breadth of rectangular sheet is 4 cm and when you cut 3 cm from it 1 cm is left.
In ΔVWX, x = 97 cm, v = 48 cm and ∠W=28°. Find the length of w, to the nearest centimeter.
The answer would be 59. This is for law of cosines (sas)
The requried length of side w is approximately 44 cm to the nearest centimeter.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc, in algebraic operations.
To find the length of side w in ΔVWX, we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in the triangle. In other words:
w/sin(W) = x/sin(X)
where X is the angle opposite side x.
We are given x = 97 cm, v = 48 cm, and W = 28°. To find X, we can use the fact that the sum of the angles in a triangle is 180°:
X = 180° - W - V
X = 180° - 28° - 180°/2
X = 72°
Now we can plug in the values into the law of sines equation:
w/sin(28°) = 97/sin(72°)
Solving for w, we get:
w = sin(28°) * 97 / sin(72°) = 43.9 cm
Therefore, the length of side w is approximately 44 cm to the nearest centimeter.
