Step-by-step explanation:
7x+10 - (x+2)^2
7x+10 - (x^2 + 2x + 4)
7x+ 10 - x^2 - 2x - 4
5x + 6 - x^2
then if u have to find the value of x then put the value of a = 1,b = 5,c = 6 in quadratic formula (-b + under root b^2 - 4ac / 2a) or (- b - under root b^2 - 4ac / 2a) it will gives the value of x...
HOPE it u..!!
edit - do let me knw that it's right or not..!!
Answer: C) f ≥ 35s - 200
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
She needs 35 frames (f) per second (s) ( we have to multiply the number of frames by the number of seconds) f ≥ 35s
She has already 200 frames (since we already have, we can subtract that to the needed frames per second)
f ≥35s -200
Feel free to ask for more if needed or if you did not understand something.
Answer:
6 hours. ( I DID IT USING PROPORTIONS!)
Step-by-step explanation:
houses/hours
130/2.5= 312/x
(cross multiply)
130x = 780
130x/130 = 780/ 130 (divide each by 130)
6 = h
Answer:
Diverges
Step-by-step explanation:
We can solve this by using integral by parts:
Let



We can add
to both sides

We can evaluate the limit between 2 and infinity.
If x tends to infinity the limit will be infinity and therefore the integral diverges to ∞
The answer is C.
∠STR = ∠SRQ = 90° (given) (A)
∠RST = ∠RSQ (common angle) (A)
By AA test for similarity,
∆STR is similar to ∆SRQ.
