Answer:
-2 3/5, -9/4, 1.2, 7/4
Step-by-step explanation:
First, unmix the mixed numbers.
-9/4 = -2 1/4.
Which is greater?
1/4 vs. 3/5
Answer: 3/5 So...
-2 3/5 would be the least.
Then there would be -2 1/4
Then, it would be 1.2 because 1.2 is smaller than 7/4.
Therefore, this pattern would be the correct answer...
From Least to greatest=
-2 3/5, -9/4, 1.2, 7/4

5 1/10 x 1/6 pls helppp
Answer:
51/60
Step-by-step explanation:
First, I'll convert 5 1/10 into an improper fraction to make it easier to work with. I get 51/10. Then, I multiply the two fractions like so:
51/10 * 1/6 = 51/60
You multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately.
So the answer is 51/60.

$5400 at 3.6% compounded continuously for 5 years.
Answer:
A = $6,464.97
Step-by-step explanation:
Given the principal amount of $5,400, and an interest rate of 3.6% compounded continuously for t = 5 years:
Substitute the given values into the Continuous Compounding Formula:
[tex]A = Pe^{r*t}[/tex]
where:
P = principal = $5,400
e ≈ 2.7183 (irrational number)
r = interest rate = 3.6% or 0.036
t = time in years = 5
[tex]A = Pe^{r*t}[/tex]
[tex]A = 5400e^{(0.036*5)}[/tex]
[tex]A = 5400e^{0.18}[/tex]
A = $6,464.97
Therefore, the amount after compounding continuously for 5 years is $6,464.97.

Round 19.432 to the nearest whole
The nearest whole number is 20.
Answer:
19
Step-by-step explanation:
if the number was 19.5 or later up to 20 then the answer would have been 20
but your number was 19.432 which is less then 19.5 so the your answer is 19.

ron goes to a shop to buy some notebooks. the shopkeepers informs him that 2 notebooks would cost $90. can you find the cost of 5 notebooks with the help of unitary method
Answer: $225
Step-by-step explanation:
Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2
Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225
- Gage Millar, Algebra 2 Tutor
Answer:
$225 = 5 note books.
45 = 1 note book
Step-by-step explanation:
90/2 = $45 EACH
Unitary method means find 1 part first.
Therefore,
1 part = 45
45 x 5 = 225
$225 = 5 note books.

I'm trying to find the explicit form of an equation after performing an integration. I'm a bit rusty.
ln|y| = C - cos(x)
C is an arbitrary constant.
Is it:
y = e^(c-cos(x))
or because it's an arbitrary constant, can it be written:
y = C - e^(cos(x))
Thanks.
No, it should be written as
[tex]y = Ce^{-\cos x}[/tex]
Provided that y ≠ 0, both solutions
[tex]y = e^{C-\cos(x)}[/tex]
and
[tex]y = Ce^{-\cos(x)}[/tex]
are correct. The other solution you provided,
[tex]y = C - e^{\cos(x)}[/tex]
is not.
The only difference between the "valid" solutions lies in the particular value of the arbitrary constant C.
Suppose y(0) = Y ≠ 0 is given as an initial condition. Then in the first solution,
[tex]Y = e^{C - \cos(0)} \implies \ln|Y| = C - 1 \implies C = \ln|Y| + 1[/tex]
In the second solution,
[tex]Y = C e^{-\cos(0)} \implies Y = Ce^{-1} \implies C = eY[/tex]
But both solutions are the same, since
[tex]y = e^{\ln|Y| + 1 - \cos(x)} = e^{\ln|Y|} e^1 e^{-\cos(x)} = eY e^{-\cos(x)}[/tex]

Answer: x=120 degrees
Step-by-step explanation: Since this triangle is equilateral, each of its angles equals 60 degrees. The line that x is on is equal to 180 degrees, so subtracting 60 from 180 will give you 120 degrees for x.
Answer:
x=180°-60°=120°, bc In an equilateral triangle, the angles are equal and equal to 60°
Step-by-step explanation:
Points A and B are 100m apart on a coastline.
B is directly east of A.
A lighthouse is out at sea.
The bearing of the lighthouse is
164 degrees from A and
217 degrees from B
The angle of elevation of the top of the lighthouse from A is 27 degrees.
Find the distance of the lighthouse from A.
Find the height of the lighthouse.
Points A, B and the lighthouse are related by angles of elevation.
The distance of the lighthouse from A is 97.4 mThe height of the lighthouse is 79.9 mFrom the complete question (see attachment), we have:
[tex]\mathbf{\angle A = 164 - 90}[/tex]
[tex]\mathbf{\angle A = 74}[/tex]
[tex]\mathbf{\angle B = 270 - 218}[/tex]
[tex]\mathbf{\angle B = 52}[/tex]
[tex]\mathbf{\angle L = 180 - 74 - 52}[/tex]
[tex]\mathbf{\angle L = 54}[/tex]
(a) The distance between the lighthouse and A
This is calculated using the following sine ratio
[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]
So, we have:
[tex]\mathbf{\frac{AL}{sin B} = \frac{100}{sin L}}[/tex]
This gives
[tex]\mathbf{\frac{AL}{sin 52} = \frac{100}{sin 54}}[/tex]
Make AL the subject
[tex]\mathbf{AL = \frac{100}{sin 54} \times sin 52}[/tex]
[tex]\mathbf{AL = 97.4}[/tex]
The distance of the lighthouse from A is 97.4 m
(b) The height of the lighthouse
Considering triangle AHL, we have:
[tex]\mathbf{\angle H = 90 + 27 = 117}[/tex]
[tex]\mathbf{\angle A = 74 - 27 = 47}[/tex]
[tex]\mathbf{AL = 97.4}[/tex]
The height is then calculated using the following sine ratio
[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]
So, we have:
[tex]\mathbf{\frac{AL}{sin H} = \frac{HL}{sin A}}[/tex]
Make HL the subject
[tex]\mathbf{HL = \frac{AL \times sin A}{sin H}}[/tex]
This gives
[tex]\mathbf{HL = \frac{97.4 \times sin 47}{sin 117}}[/tex]
[tex]\mathbf{HL = 79.9}}[/tex]
Hence, the height of the lighthouse is 79.9 m

HOW IS THE ANSWER 98 PLS HELP ASAP
Answer:
The answer is 98, here's how:
Step-by-step explanation:
Lets solve the numerator of the fraction first:
-[5.8 - 3(3.2)] =
-[5.8 - 9.6] =
-[-3.8] = 3.8 (Watch out for the double negative)
Now lets solve for the denominator :
(-0.2)² =
(-0.2)(-0.2) = 0.04
Lets simplify the fraction:
[tex]\frac{3.8}{0.04} = 95\\[/tex]
Let's add the 3 to 95:
95 + 3 = 98
-Chetan K
Step-by-step explanation:
[tex] \frac{ -[5.8 - 3(3.2)] }{{( - 0.2)}^{2} } + 3[/tex]
[tex]\frac{ -[5.8 -9.6] }{0.04 } + 3[/tex]
[tex]\frac{ -( - 3.8)}{0.04} + 3[/tex]
[tex]\frac{3.8}{0.04} + 3[/tex]
[tex] = 95 + 3[/tex]
[tex] = 98[/tex]
