Answer:
[tex]h^2-3h+5\:\text{remainder }3 \text{ or }h^2-3h+5-\frac{3}{h+3}[/tex]
Step-by-step explanation:
Question: [tex]\frac{h^3-4h+12}{h+3}[/tex] (divide using long division)
To start, our quotient must have a degree of 2, since [tex]h\cdot h^2=h^3[/tex].
From long division, multiply by the highest degree possible with appropriate constants to ride terms of the dividend when necessary. When you finish, the final term at the bottom will be your remainder and your quotient will be on top (in long division form).
The result is [tex]\frac{h^3-4h+12}{h+3}=h^2-3h+5\text{ with a remainder of } 3[/tex]. You can write it in quotient-remainder form, or as one long polynomial: [tex]\implies h^2-3h+5-\frac{3}{h+3}[/tex].
Verify:
[tex](h^2-3h+5)(h+3)=h^3-4h+15=\bold{h^3-4h+12}+\underline{3} \:\checkmark[/tex]
A circular plate has a circumference of 37.7cm. Calculate the diameter of the plate.
Circumference of circle = 2πr
Putting values ::-
37.7 = 2 × 3.14 × r
r = 37.7 ÷ 6.28
r = 6.003 (approx)
therefore,
d = r × 2 = 6.003 × 2
d = 12.006
.·. Diameter of plate ≈ 12 cm.
In ΔIJK, k = 57 inches, i = 37 inches and ∠J=141°. Find ∠I, to the nearest degree.
Answer:
<I= 15degrees
Step-by-step explanation:
Using the cosine rule formulae;
j² = i²+k²-2i cos <J
j² = 37²+57² - 2(37)(57)cos <141
j² = 1369+ 3249- 4218cos <141
j² = 4618- 4218cos <141
j² = 4618-(-3,278)
j²= 7,896
j = √7,896
j = 88.86inches
Next is to get <I
i² = j²+k²-2jk cos <I
37² = 88.86²+57² - 2(88.86)(57)cos <I
1369 = 7,896.0996+ 3249- 10,130.04cos <I
1369 = 11,145.0996 - 10,130.04cos <I
1369 - 11,145.0996 = - 10,130.04cos <I
-9,776.0996=- 10,130.04cos <I
cos <I =9,776.0996 /10,130.04
cos<I = 0.96506
<I = 15.19
<I= 15degrees

(1) At the local nursery, 1/2 of the plants for sale are flowers and another 1/10 of them are
bushes. What fraction of the plants for sale are either flowers or bushes?
Answer:
6/10
Step-by-step explanation:
Look at is a whole. Half the plants are flowers, and just a few are bushes. That leaves other plants that are neither.
We can find a total amount of plants that are either flowers or bushes by combining the two.
Because 1/2 and 1/10 are not currently combinable, you must find a common denominator. This common denominator is 10. If you multiply 2 by 5, you'll get 10.
[tex]\frac{1}{2} +\frac{1}{10}[/tex]
[tex]\frac{5}{1} (\frac{1}{2} )+\frac{1}{10}[/tex]
[tex]\frac{5}{10} +\frac{1}{10}[/tex]
[tex]\frac{6}{10}[/tex]
This means that 6/10 of the whole number of plants are either flowers or bushes. You could also say it means that 4/10 of the plants are something other than flowers or bushes.

-1 1/4 + (-2 1/2)
anyone ty
Answer:
-3 3/4
Step-by-step explanation:
So we have:
-1 1/4 + (-2 1/2)
Before solving this, lets just clean it up.
First off, since we know that a + and - sign equals a - sign, we can rewrite it as:
-1 1/4 - (2 1/2)
We need to also get a common denominator, which would be 4. The first fraction already has a denominator of 4, so it doesnt change. However, the second fraction is 1/2, and we need to multiply both sides by 2 to change the denominator from 2 to 4:
-1 1/4 - (2 2/4)
Now lets solve:
I will do the fraction seperate from the whole number to make it simpler:
-1 - 2
A negative subtracted makes it a larger negative so:
-3
-1/4 - 2/4
Again, a negative subtracted makes it a larger negative:
-3/4
Now recombine the numbers:
-3 3/4
So this is your answer.
Hope this helps!
please help! i think the answer is 12 but any verification would be greatly appreciated!

Answer:
Option B
Step-by-step explanation:
For increasing function in the interval (a, b),
"If we draw a tangent at any point on the graph in the given interval (a, b), slope of the tangent drawn will be positive"
Given function is,
[tex]f(x)=\frac{1}{2}x^2+5x+6[/tex]
In the interval (-∞, -5),
Graph is moving downwards therefore, tangents drawn at any point will have a negative slope and the function will decrease in this interval.
In the interval (-5, ∞),
In the given interval any tangent drawn at any point will have a positive slope and the function will be increasing.
Therefore, interval in which the function is increasing → (-5, ∞)
Option B is the answer.
The interval in which the function decreases is (-∞, -5).
In which interval the function decreases?The function decreases when, reading from left to right, the graph of the function goes downwards.
By looking at the graph, we can see that the graph goes downwards on the interval negative infinity and -5
Then we conclude that the function decreases on the interval (-∞, -5).

What is the relative frequency (to the nearest percent) of boys among those who cannot bike to school
Answer:
29%
Step-by-step explanation:
From the two way table given : the relative frequency of boys among those who cannot bike to school ;
Here, we are only concerned with thilose who cannot Bikento school and not all of the data :
The relative frequency of boys among those who cannot bike to school is :
Number of boys who can't bike to school / total number of people who can't bike to school
Number of boys who can't bike = 4
Total who cannot bike = 14
Hence, 4 /14 = 0.2857142
0.2857142 * 100% = 28.57% = 29% (nearest percent)

Calculate the total surface area and the volume of a cone of base diameter 9cm and slant height of 12cm
Answer:
T.S.A = 233.29 cm²
volume of the cone = 235.84 cm³
Step-by-step explanation:
Given;
diameter of the cone, d = 9 cm
radius of the cone, r = 4.5 cm
slant height of the cone, l = 12 cm
The total surface of the cone is calculated as;
T.S.A = πr² + πrl
T.S.A = πr(r + l)
T.S.A = 3.142 x 4.5(4.5 + 12)
T.S.A = 233.29 cm²
The volume of the cone is calculated as;
[tex]V = \frac{1}{3} \pi r^2h[/tex]
Where;
h is height of the cone
h² = 12² - 4.5²
h² = 123.75
h = √123.75
h = 11.12 cm
[tex]V = \frac{1}{3} \pi \times (4.5)^2 \times 11.12\\\\V = 235.84 \ cm^3[/tex]

864π cu. in.
C.
3,456π cu. in.
D.
6,912π cu. in.
Answer:
B. 864π cu. in.
Step-by-step explanation:
Given the following data;
Diameter = 24 inches
Radius, r = diameter/2 = 24/2 = 12 inches
Height, h = radius/2 = 12/2 = 6 inches
To find the volume of the cylinder in cubic inches;
First of all, we would determine the area of its circular base.
Area of circle = πr²
Area = π * 12²
Area = 144π in² (in terms of pie, π)
Next, we would find the volume of the cylinder;
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.Substituting into the formula, we have;
Volume = 144π * 6
Volume = 864π cu. in
Answer:
B. 864π cu. in.

Ryan spent $3.25 on lunch every day, Monday through Friday. If he had $20 at the start of the week, how much money did he have left after Friday
Monday through Friday is 5 days.
Multiply the cost of lunch by number of days:
3.25 x 5 = $16.25
Subtract the total he spent on lunch from what he started with for money:
20 - 16.25 = 3.75
He had $3.75 left.
Answer:
He had $3.75 dollars left.
Step-by-step explanation:
He was spending launch money for five days so:
3.25*5 is the total amount of money he spent that week.
The amount of Mooney he had minus the amount of money he spent is the amount of money left.
20-3.25*5= 3.75

This is modeled after an exponential function which, at its simplest, is
[tex]y=a(b)^x[/tex] where, for us and in this particular situation, y is the final height, a is the initial height, b is the rate of growth or decline, and x is the number of bounces. We know the initial height is 20, but we need to find the rate of decline. Rewriting the formula to model a rate of decay or decline is
[tex]y=a(1-r)^x[/tex], or more closely related to our circumstances:
[tex]H=20(1-.8)^n[/tex] and simplifying that a bit:
