Given the polynomial f(x), if (x-1) is a factor, what else must be true?

1 answer:

4 0

B. f(1)=0 is true because if you factor a polynomial then that means you are solving for the zeros of the function or when f(x)=0.

The lengths of the legs of a right angle triangle 12 cm and 35 cm. What is the length of the hypotenuse?

love history [14]

We can use the pythagorean theorem.

Allow x to be the hypotenuse.

12^2+35^2=x^2
144+1225=x^2
1369=x^2
x=37

The area of the square is 100 square centimeters. What is the area of the circle?

Setler79 [48]

$length \: of \: 1 \: side = diameter$

$area \: = {l}^{2} \\ 100 = {l}^{2} \\ \sqrt{100} = l \\ l = 10$

$diameter = 2 \times radius \\ 10 = 2 \times radius \\ radius = 5$

$circle \: area = pi \times {r}^{2} \\ circle \: area = 3.142 \times {5}^{2} \\ circle \: area = 3.142 \times 25 \\ circle \: area = 78.55 {cm}^{2}$

A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil. How many cups of oil are needed for each cup of vinegar?

Akimi4 [234]

Answer:

$2\frac{2}{3} \ cups$ of oil are needed for each cup of vinegar.

Step-by-step explanation:

Given:

A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil.

Now, to find the cups of oil are needed for each cup of vinegar.

So, we solve by using unitary method:

If $\frac{1}{4}$ cup of vinegar is needed for oil of $\frac{2}{3}$ cup.

So, 1 cup of vinegar is needed for oil of = $\frac{2}{3} \div\frac{1}{4}$

= $\frac{2}{3}\times 4$

(the fractions turns reciprocals as the division changes into multiplication)

= $\frac{8}{3}$

= $2\frac{2}{3}$ cups.

Therefore, $2\frac{2}{3} \ cups$ of oil are needed for each cup of vinegar.

Event A has a 0.3 probability of occurring and event B has a 0.4 probability of occurring. A and B are independent events. What

Ipatiy [6.2K]

There is a 99.3 chance that neither occur cause you would add 0.3 and 0.4 together and get 0.7 then you would subtract 100 and 0.7 and get 99.3. So your answer is 99.3. Hope this helped :D
