find the diameters of a circle with a circumference of 443 feet use 3.14 for n a. 70.5 b. 141 c.142 d.282

zvonat [6]

The formula for diameter is:

circumference/pi (3.14)

If the circumference is 443, we can divide that by pi.

$443/3.14=141.01$

The answer would then be choice b (141).

Given f(x)=2x^2+9x+k, and the remainder when f(x) is divided x+7 is 32, then what is the value of k?

sweet-ann [11.9K]

Set up either long division or synthetic div. I'd do the latter.

Your divisor for synth. div. should be -7.

__________
Then -7 / 2 9 k
-14 +35
--------------------
2 -5 k+35 Rem is 32;
Let 32 = k + 5 and solve for k:

k = -3.

Let's check that. Is k correct?

Then -7 / 2 9 -3
-14 +35
--------------------
2 -5 -3+35 = 32

Since the rem is 32, we are correct; k = -3.
