Answer:

x2 - 10x - 1994

Step-by-step explanation:

Step 1 :

Trying to factor by splitting the middle term

1.1 Factoring x2-10x-1994

The first term is, x2 its coefficient is 1 .

The middle term is, -10x its coefficient is -10 .

The last term, "the constant", is -1994

Step-1 : Multiply the coefficient of the first term by the constant 1 • -1994 = -1994

Step-2 : Find two factors of -1994 whose sum equals the coefficient of the middle term, which is -10 .

-1994 + 1 = -1993

-997 + 2 = -995

-2 + 997 = 995

-1 + 1994 = 1993

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

x2 - 10x - 1994

Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?

damaskus [11]

Answer:

f(x)= (x+8)^2 + 200

Step-by-step explanation:

-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).

H is the x coordinate and K is the y coordinate

Zach is filling his dog's bowl with water. is it reasonable to say that Zach will need about 4 gallons of water.

pshichka [43]

It's not reasonable to give him 4 gallons because that's way too much for a dog bowl.

Based on information from Consumer Reports, a random sample of 35 thirty-gram cookies had a sample mean of 146 calories. The sta

Nonamiya [84]

Using the z-distribution, it is found that the 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).

We are given the standard deviation for the population, which is why the z-distribution is used to solve this question.

The information given is:

Sample mean of $\overline{x} = 146$ .

Population standard deviation of $\sigma = 12$ .

Sample size of $n = 65$ .

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

The critical value, using a z-distribution calculator, for a 95% confidence interval is z = 1.645, hence:

$\overline{x} - z\frac{\sigma}{\sqrt{n}} = 146 - 1.645\frac{12}{\sqrt{35}} = 143$

$\overline{x} + z\frac{\sigma}{\sqrt{n}} = 146 + 1.645\frac{12}{\sqrt{35}} = 149$

The 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).

Hi i need help with 15a(ii)

Art [367]

Answer:

x = 5/2

Step-by-step explanation:

log4(x^2+5x)-log8(x^3)=1/log3(4)

log(x^2 + 5 x) / log(4) - log(x^3) / log(8) = log(3) / log(4)

log(x (x+5))/log(4) - log(x^3) / log(8) = log(3) / log(4)

(3 log(x (x+5)) - 2 log(x^3)) / log(64) = log(3) / log(4)

3 log(x (x+5)) - 2 log(x^3) = 3 log(3)

log((3 x)/(x+5))=0

x=5/2
