The expression has no solutions
Find the general solution of the given higher-order differential equation. y''' − 7y'' + 8y' + 16y = 0
The ODE
y''' - 7y'' + 8y' + 16y = 0
has characteristic equation
r ³ - 7r ² + 8r + 16 = 0
which can be factorized as
(r - 4)² (r + 1) = 0
Then the characteristic solution to the ODE is
y(x) = C₁ e ⁴ˣ + C₂ x e ⁴ˣ + C₃ e ⁻ˣ

round your answer to the nearest hundredth BC= b ? c 2 a
Answer:
1.40
Step-by-step explanation:
When we look at the diagram, we want to find what is opposite and adjacent as well as the hypotenuse to the given degree.
AB = hypotenuse
BC = opposite
AC = adjacent
Since we are looking to find BC and we are given 2 on AC. We have opposite and adjacent which means we are using TOA in SOH-CAH-TOA. So aftrr identifying these, we can set up our equation:
tan (35) = x / 2
Tan(35) is .7002 so we can replace that part of our equation.
.7002 / 1 = x / 2
The 1 is there as a place holder. We can then cross multiply.
1 × x = 1
.7002 × 2 = 1.4004
The answer we have now is 1.4004, but we have to round to the nearest hundredth. So then, our final answer is 1.40.
BC = 1.40

What’s -4 1/2 divided by (-1 3/8) Diving Mixed Numbers with negatives?
Answer:
3 3/11
Step-by-step explanation:
The best way to divide fractions is to not divide them at all.
Convert both mixed numbers into improper fractions.
4 times 2 is 8
8 + 1 is 9
I have 9/2 halves. Don't forget to put the negative back in.
1 times 8 is 8
8 + 3 is 11
I have 11/8 eighths. Dont forget to put the negative back in.
You will end up with
-9/2 ÷ -11/8
Flip the second fraction and change the division sign to a multiply sign
-9/2 × 8/-11
Multiply the numerators together and the denominators together
-9 x 8 and 2 x -11
-72 / -22
Dividing a negative by a negative will give us a positive
72 / 22

Reward: 30 pts
Answer: see below
Step-by-step explanation:
(i)
200/2 = 100
Find 100 on cumulative frequency and the correspinding time: 14 minutes. So the answer is 14 minutes.
(ii)
First, find the lower quartile —> 200/4 = 50
Upper quartile —> 200/(3/4) = 150
Find the difference: 150 - 50 = 100
So the interquartile range is 100

Determine whether 7 is a solution of the equation 2x-5=3
Answer:
No, it is not a solution
Step-by-step explanation:
First let's simplify 2x - 5 = 3
2x - 5 = 3 (add 5 to both sides)
2x - 5 + 5 = 3 + 5
2x = 8 (divide both sides by 8)
2x ÷ 2 = 8 ÷ 2
x = 4
As you can see, 7 is not a solution for 2x - 5 = 3
We can double check by substituting 7 for x:
2(7) - 5 = 3
14 - 5 = 3
9 ≠ 3

m=y2-y1/x2-x1 solve for x2
Answer:
[tex]x2=\frac{y2-y1}{m} +x1[/tex]
Step-by-step explanation:
Step 1: Multiply both sides by (x2-x1)
m(x2-x1)=y2-y1
Step 2: Divide both sides by m
x2-x1=(y2-y1)/m
Step 3: Add x1 to both sides
[tex]x2=\frac{y2-y1}{m} +x1[/tex]

1/9 divided by 8/7 =_ the lesson is called dividing fractions
Answer:
[tex] \frac{7}{72} [/tex]
Step-by-step explanation:
The question is :
[tex] \frac{1}{9} \div \frac{8}{7} [/tex]
We need to take the reciprocal which means invert the :
[tex] \frac{8}{7} [/tex]
So, it will be :
[tex] \frac{1}{9} \times \frac{7}{8} [/tex]
After that , do 1 × 7 on numerator and 9 × 8 on denominator....
After multiplication you'll get :
[tex] \frac{7}{72} [/tex]
1/9 divided by 8/7 is equal to 7/72.
To divide fractions, you can use the following rule: invert the second fraction and multiply it by the first fraction.
In this case, you have:
1/9 ÷ 8/7
To divide, we invert the second fraction:
1/9 × 7/8
Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
(1 × 7) / (9 × 8)
This simplifies to:
7/72
Therefore, 1/9 divided by 8/7 is equal to 7/72.

if i have a cupcake tree growing 4 cupcakes every 5 hours for ten hours how many cupcakes do i have
Answer: 8 cupcakes.
Step-by-step explanation:
4 cupcakes every 5 hours implies that 4 cupcakes grow in the span of 5 hours. if this is a ten hour period as the question states, then you have 8 cupcakes, as 4 cupcake batches grew twice in that 10 hour span.

,
,
b) Is the sequence arithmetic, geometric or neither?
Answer:
a) 73, 82, 91
b) arithmetic
Step-by-step explanation:
a) We add 9 after each term, making the common difference 9.
As such, 64 + 9 = 73
73 + 9 = 82
82 + 9 = 91
b) This sequence is arithmetic because it has a common difference, if it had a common ratio, it would be geometric.
