Answer:

B

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = \frac{1}{\sqrt{2} } , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{3}{c} = \frac{1}{\sqrt{2} } ( cross- multiply )

c = 3\sqrt{2}

Answer:

See below

Step-by-step explanation:

Problem 1

If n is the smallest of the consecutive integers, the next integer would be n+1.

Problem 2

The equation is terms of n is going to be

s = n + n + 1 + n + 2 + n+3

Problem 3

Collect like terms on the right

s = 4n + 6

Problem 4

4n + 6 = s             Subtract 6 from both sides

4n = s - 6              Divide by 4

n = (s - 6)/4

Problem 5

Solve for n when s = 2174

n = (2174 - 6)/4

n = 2168 / 4

n = 542

check

n                 = 542

n + 1            = 543

n + 2           = 544

n + 3     <u>      = 545</u>

Total            2174         Just as it should

Given the functions k(x) = 2x2 − 5 and p(x) = x − 3, find (k ∘ p)(x). (k ∘ p)(x) = 2x2 − 6x 4 (k ∘ p)(x) = 2x2 − 12x 13 (k ∘ p)(
jeka57 [31]

(k \circ p)(x)=k(p(x))=k(x-3) \\ \\ =2(x-3)^2-5 \\ \\ =2(x^2 - 6x+9)-5 \\ \\ =\boxed{2x^2 - 12x+13}

Which number has the prime factorization 5 · 72 · 32?
lubasha [3.4K]

Answer:

see below

Step-by-step explanation:

5*72*32 is not a prime factorization to begin with because neither 72, nor 32 are primes. A prime factorization for this product would be:

2*2*2*2*2*2*2*2*3*3*5

and the number with this factorization is 11520.

There is a small chance that what you meant to write was this: 5\cdot 7^2 \cdot 3^2 in which case the number for this prime factorization is 2205.
