Answer:
40
Step-by-step explanation:
16+24=40
40-16=24
Answer:
a = 40
Step-by-step explanation:
Add 16 on both sides
a - 16 + 16 = 24 + 16
a = 24 +16 = 40
a = 40
Verification
LHS = a - 16 a = 40
40 - 16 = 24
RHS = 24
Both LHS and RHS are same so, our answer is correct.

The graph of the equation is f ( x ) = x⁴ - x³ - 3x² + 3
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the equation of the graph be represented as A
Now , the value of A is
f ( x ) = x⁴ - x³ - 3x² + 3
There are no asymptotes for the function
And , the graph of the function is plotted below
Hence , the equation is f ( x ) = x⁴ - x³ - 3x² + 3

friend get to eat?
will make brainlest and rate 5 stars and say thanks
you could solve this problem one of two ways-
1)
100/4 25/2 12.5
100, equals the entire pizza. 4, is the number of people. 25, is the amount they all get. They you divide by 2 since it is only a half pizza.
-or-
2)
100/2 50 50/4 12.5
100, equals the entire pizza. Divide that by 2 since it half a pizza. 100/2 equals 50. Then, since there is 4 friends you divide 50 by 4. Which equals 12.5.
In conclusion, the final answer is 12.5% of the pizza each.

The probability that exactly two of the marbles are red is . What is the probability that none of the marbles are red? The probability of picking no red marbles is .
Answer:
ALL RED = 19/5000
Two Red = 3831/10000
No red marbles = 16/26
Step-by-step explanation:
1. Find the total number of marbles
7+10+9= 26
2. There are 10 red marbles so the probability that the first marble is red 10/26
3. When the second marble there are 25 marbles so the probability that it is red is 9/25
4. Third Marble probability
8/24
5. Fourth Marble probablity

Type answer as a number without the $ symbol rounded to the hundredths. Example, if it
the answer was $1234.5687, you would enter 1234.57.
Answer:
The computation of the given question is shown below:-
Total Contributions = Monthly contribution + Amount invested in Ferdinand’s 401(k)
= $250 + $125
= $375
1. Future Value = PMT [((1 + r)n - 1) ÷ r
Future value = 375 × ((1 + 0.03 ÷ 12) × 12 × 40 - 1) ÷ (0.03 ÷ 12)
= $347,272
2. Ferdinand deposit = Given Amount × Total number of months in a year × Number of years
= $250 × 12 Months × 40 Years
= $120,000
3. The Amount put in by the employer = 50% of $250 ×Total number of months in a year × Number of years
= $125 × 12 Months × 40 Years
= $60,000
4. Interest = Future value - Ferdinand deposit - The Amount put in by the employer
= $347,272 - $120,000 - $60,000
= $167,272

Find the area of a regular nonagon with a radius of 4
If it's a regular nonagon, each exterior angle has measure 360°/9 = 40°, so the supplementary interior angles each have measure 180° - 40° = 140°.
We can split up the nonagon into 9 congruent isosceles triangles whose longer side coincides with the radius of the circle. (The language in the question is a bit ambiguous; I think it's clearler to say the nonagon is itself circumscribed by the circle, so that each of its vertices lie on the circle. See attached image - not mine, but it's in public domain.)
As the image suggests, each triangle will have interior angles measuring 70°, 70°, and 40°.
We can use trigonometry to find the side length of the nonagon, i.e. the length of the shortest side of each triangle - I'll call it x. For example, using the law of cosines,
x² = 4² + 4² - 2 • 4 • 4 cos(40°) ⇒ x = 4√2 √(1 - cos(40°))
Then the perimeter of the nonagon is
9x = 36√2 √(1 - cos(40°)) in ≈ 24.623 in
The area of a triangle is 1/2 the product of its base and height. The base will be b = x, but to get the height we cut the isosceles triangle in half to produce a right triangle. We use trig again to determine its height h:
tan(70°) = h/(b/2) ⇒ h = 1/2 x tan(70°)
so each triangle contributes an area of
a = 1/2 bh = 1/4 x² tan(70°) ≈ 5.142 in²
and so the area of the nonagon is
9a = 9x²/8 tan(70°) ≈ 46.281 in²

Answer:
1. 3. 4. 2.
Step-by-step explanation:
All the given linear relationships are given in slope-intercept form
y = mx + b (where m is the slope and b is the y-intercept).
The slope (gradient) of the line represents the rate of change. Therefore, we need to examine the slope of each relationship, and order them accordingly.
Solution
From least rate of change to greatest rate of change:
1. y = 2x + 7
3. y = 3x
4. y = 4x + 6
