Answer: -6
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
Rule: When multiplying or dividing two numbers with the same sign (both positive or both negative), the answer is positive. When multiplying or dividing two numbers with different signs (one positive and one negative), the answer is negative.
Here you have a negative number and a positive number. Since their signs are different, the product is negative.
(-3) * 2 = -6

Find the average rate of change from 1 to 6
Let f(x)=8x-3
Answer:
8
Step-by-step explanation:
To find the average rate of change we use the function
[tex]f(x) = \frac{f(b) - f(a)}{b - a} \\ f(x) = \frac{f(6) - f(1)}{6 - 1} \\ \frac{(8(6) - 3) - (8(1) - 3)}{5} \\ \frac{48 - 3 - (8 - 3)}{5} \\ \frac{45 - 5}{5} \\ \frac{40}{5} \\ 8

(10 pts) (a) (2 pts) What is the difference between an ordinary differential equation and an initial value problem? (b) (2 pts) What is the difference between a particular solution and a general solution? (c) (3 pts) Given an example of a second-order linear ODE and a second-order nonlinear ODE that is not in the text, Chapter 1. (d) (3 pts) Give an example of a nonlinear 4th-order ordinary differential equation.
Answer:
Step-by-step explanation:
(A) The difference between an ordinary differential equation and an initial value problem is that an initial value problem is a differential equation which has condition(s) for optimization, such as a given value of the function at some point in the domain.
(B) The difference between a particular solution and a general solution to an equation is that a particular solution is any specific figure that can satisfy the equation while a general solution is a statement that comprises all particular solutions of the equation.
(C) Example of a second order linear ODE:
M(t)Y"(t) + N(t)Y'(t) + O(t)Y(t) = K(t)
The equation will be homogeneous if K(t)=0 and heterogeneous if [tex]K(t)\neq 0[/tex]
Example of a second order nonlinear ODE:
[tex]Y=-3K(Y){2}[/tex]
(D) Example of a nonlinear fourth order ODE:
[tex]K^4(x) - \beta f [x, k(x)] = 0[/tex]
27. Reason Adam invests $8,000 in an account that
earns 1.25% interest, compounded quarterly
for 20 years. On the same date, Jacinta invests
$8,000 in an account that earns continuous
compounded interest at a rate of 1.25% for
20 years. Who do you predict will have more
money in their account after 20 years? Explain
your reasoning.
Answer:
Jacinta will have more money
Step-by-step explanation:
For the same amount of investment and interest rate, compound interest is greater with greater number of compounds.Continuous compound is closer to daily compound which makes more compounds and returns than quarterly compound.The interest amount is provided below for quarterly and daily compound:
2,268.202,307.89Jacinta will have more money

Answer:
1278.8 ft^3
Step-by-step explanation:
radius of cylinder = r = 5.8 ft
height of cylinder = h = 8.9 ft
radius of cone = r = 5.8 ft
height of cone = H - h = 18.5 ft - 8.9 ft = 9.6 ft
volume = volume of cylinder + volume of cone
V = (pi)(r^2)h + (1/3)(pi)(r^2)(H - h)
V = (3.14159)(5.8^2 ft^2)(8.9 ft) + (1/3)(3.14159)(5.8^2 ft^2)(9.6 ft)
V = 1278.8 ft^3
Answer:
If you use 3.14 for pi
1278.1 ft^2
Using the pi button on the calculator
1278.8 ft^2
Step-by-step explanation:
First find the volume of the cylinder
V = pi r^2 h where r is the radius and h is the height of the cylinder
V = pi ( 5.8) ^2 ( 8.9)
V = pi *33.64 * 8.9
V = 299.396 pi
The find the volume of the cone
V= 1/3 pi r^2h
The height of the cone is 18.5- 8.9 =9.6
V= 1/3 ( pi ) ( 5.8)^2 ( 9.6)
V= 1/3 ( pi ) 33.64 ( 9.6)
V = 107.648 pi
Add the two volumes together
299.396 pi + 107.648 pi
407.044 pi
If you use 3.14 for pi
1278.11816 ft^2
Rounding to the nearest tenth
1278.1 ft^2
Using the pi button on the calculator
1278.76644
Rounding to the nearest tenth
1278.8 ft^2
How do you do number 4 cuz omggg
LM + MN = LN
5x + 5 = 11x - 1
Add 1 to both sides and subtract 5x from both sides
6 = 6x
Divide each side by 6
1 = x
MN = 5
LM = 5(1) = 5
LN = MN + LM = 5 + 5 = 10
There are 34 people in a restaurant. Four groups of 3 people leave, and then
5 groups of 2 people arrive. Evaluate the expression 34 4 3 5 2 −•+• to
determine how many people are in the restaurant.
Answer:
22 people
Step-by-step explanation:
If 4 groups of 3 people leave, multiply:
4 x 3 = 12
5 groups of 2 people leave, multiply:
5 x 2 = 10
Now add:
12 + 10 = 22 people that left the restaurant.

6x+14y=28 in slope incerpt form?
Answer:
y = -2/7x + 2
Step-by-step explanation:
If we rewrite 6x+14y=28 into slope intercept form, it becomes 14y = -6x +28. When we divide the whole thing by 14 to get a singular y, -6x becomes -2/7x since 6/14 = 2/7, and 28 becomes 2.

Best of Luck!
Answer:
384
Step-by-step explanation:
[tex]3[(8-4)^5][/tex]÷[tex]8[/tex]
Using the rules of PEMDAS I know that I have to do the math inside of the parenthesis first.
8 - 4 = 4
Our new equation is
[tex]3[(4)^5][/tex]÷[tex]8[/tex]
Next we have to solve for the exponent.
[tex]4^5[/tex] = [tex]4*4*4*4*4[/tex] = 1,204
Our new equation looks like:
[tex]3[1024][/tex]÷[tex]8[/tex]
Now we will multiply, because we follow the rules of operation.
[tex]3 *1024= 3072[/tex]
Finally we will divide 3,072 by 8.
[tex]3072/8= 384[/tex]
Our final answer is:

A tree is 66 inches tall. How tall is it in feet and inches?
Answer:
5 feet and 6 inches
Step-by-step explanation:
5 feet is 60 inches
Answer:
5 feet 6 inches
a foot is 12 inches. Go by 12s until you get to a number that's as close as you can make it without going overboard, then count what's left. 12 × 5 = 60, 66 - 60 = 6, hence 5 feet 6 inches

Area of a square = side^2
In this problem,
Side = 4in
Therefore,
Area = 4^2 = 16in^2
Area of a rectangle = length * width
In this problem,
Length = 6in
Width = 12.5in
Area = 75in^2
Area of a parallelogram = base * height
In this problem
Base = 10in
Height = 3.5in
Area = 3.5 * 10 = 35in^2
Now we add up the area from each shape
35 + 75 + 16 = 126in^2
Let X be a binomial random variable with p=0.3 and n=15. What is P(X=5)?
Answer:
0.20613038098
Step-by-step explanation:
The formula for Binomial Probability =
P(X) =[ n!/(n - x)! × x! ] × p^x × q^n - x
From the question
x = 5
n = 15
p = 0.3
q = 1 - p
= 1 - 0.3 = 0.7
P(x = 5) = [15!/(15 - 5)! × 5! ] × 0.3^5 × 0.7^15 - 5
P(x = 5) = 3,003 × 0.3^5 × 0.7^10
P(x = 5) = 0.20613038098
Therefore, P(x = 5) = 0.20613038098

They are neither congruent nor similar.
The triangles UVW and XYZ are concurrent and similar, so option A is correct.
What is triangle?Triangle is one of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices, known as triangle.
Given:
Angles VUW and ZXY are congruent, angles UWV and XZP are congruent, and angles UVW and ZYX are congruent. The length of side UV is 50, the length of VW is 60, and the length of UW is 40. The length of side ZY is 48, the length of YX is 40, and the length of ZX is 32.
Here the triangles are congruent by the AAA congruence and the length of the first triangle is in the ratio 40:50:60 = 4:5:6 and the side of the second triangle is also in the ratio 32:40:48 = 4:5:6 therefore they are also similar.
