please solve for U as soon as possible.
Answer:
u = the square root of ([tex]v^{2} - 2 as[/tex])
Step-by-step explanation:
I could not figure out how to get [tex]v^{2} - 2as[/tex] under the square root symbol so I typed it out in the answer. To solve for u, we subtract 2as from both sudes and then take the square root of both sides. Hope this helps!

find the value of
[tex] {x}^{2} + {y}^{2} + 6xy[/tex]
Answer:
32
Step-by-step explanation:
x²+y² = 11 equation--(i)
2xy = 7 equation--(ii)
Here,
= x²+y²+6xy
= 11 + 6xy (x²+y² = 11 from equation--(i))
= 11 + 3 × 2xy
= 11 + 3 × 7 (2xy = 7 from equation --(ii))
= 11 + 21
= 32

Answer:
3/10
Step-by-step explanation:
Answer: 3/10
Work (Easy Method): So the easy method is to count how many spaces are there, and since there are 10, you choose the 3/10
Work (Harder Method): You count the White spaces in both, and put it over the total spaces, So, since there's 4 white spaces in Tracy, and 10 total spaces, you do 4/10, and same goes with Carol. So, you just subtract 7/10 by 4/10, and you get 3/10

The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...? an = 4 · ( ) n - 1 an = 2 · 4 n - 1 an = 32 · 2 n - 1 an = 4 · 2 n - 1
Answer:
an = 4 · 2^(n - 1)
Step-by-step explanation:
Given:
an = a1 · r^(n - 1)
Where,
an = value of the n th term
a1 = value of the first term
r = common ratio
n = the term number.
What is the formula for the geometric sequence 4, 8, 16, 32, ...?
a1 = 4
r = 8/4
= 2
n = n(not given)
Substitute the values of a1 and r into the formula
a1 = 4
r = 2
an = a1 · r^(n - 1)
an = 4 * 2^(n - 1)
The correct answer is:
an = 4 · 2^(n - 1)
Answer:
an = 4 · 2^(n - 1)

A number consists of two digits. The sum of its digits is 16. If 28 is subtracted from the number, the digits interchange their place. Find the number. |.Give the answer only
Answer:
The number is 97Step-by-step explanation:
Note: The difference should read 18 not 28, it must be a typo. In general such difference must be a multiple of 9.
Let the digits are x and y.
If the first digit is x and the second digit is y, then the number is 10x + y.
According to the question we have:
x + y = 1610x + y - 18 = 10y + x ⇒ 9x - 9y = 18 ⇒ x - y = 2Add up the equations:
x + y + x - y = 16 + 22x = 18x = 9Find y:
9 + y = 16y = 7The number is 97.

5/8 divided by 1/3 in simplest form
Answer: 1-7/8.
Step-by-step explanation;
Division of fractions is equivalent to multiplication by the reciprocal of the second fraction: 5/8 / 1/3 = 5/8 * 3/1.
Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values: 15/8.
15 ÷ 8 = 1R7, therefore: 1-7/8.
The required, 15/8, is the simplest form. It cannot be further reduced since the numerator (15) and the denominator (8) have no common factors other than 1.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. Let's calculate the division:
(5/8) ÷ (1/3)
Find the reciprocal of the second fraction:
Reciprocal of (1/3) = 3/1 = 3
Now, multiply the first fraction by the reciprocal of the second fraction:
(5/8) * 3 = (5 * 3) / 8 = 15 / 8
So, the answer to 5/8 divided by 1/3 in simplest form is 15/8.

r = 4 in., θ = 11 rad; find s
Answer:
The arc length s = 44 inches
Step-by-step explanation:
We are given:
r = 4 in
Ф = 11 radians
We need to find s
The formula used is: [tex]s=r\theta[/tex]
where s represents arc length, r is radius and Ф is angle in radians
Putting values and finding s
[tex]s=r\theta[/tex]
Put r = 4 and Ф = 11
[tex]s=4\times 11\\s=44[/tex]
So, the arc length s = 44 inches
