What is the minimum value for g(x)=x^2-10x+16? Enter your answer in the box.

Anna71 [15]

Answer:

- 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

g(x) = x² - 10x + (- 5)² - (- 5)² + 16

= x² - 10x + 25 - 25 + 16

= (x - 5)² - 9 ← in vertex form

vertex = (5, - 9), hence

minimum value = - 9

Find the value of y

Rainbow [258]

You'll apply the geometric mean formula. The idea is to multiply the two pieces of the hypotenuse: 5*11 = 55

Then apply the square root to get sqrt(55)

The exact answer in terms of radicals or square roots is sqrt(55)

Using a calculator, the approximate answer is sqrt(55) = 7.416198

If your teacher wants you to use a proportion, then one way to do it is to have
11/y = y/5
11*5 = y*y
55 = y^2
y^2 = 55
y = sqrt(55)
y = 7.416198 approximately

Altogether Central High School's bands have 40 trumpets and 35 tubas. Carlee says the ratio of trumpets to tubas is 40:35. Danny

inna [77]

Answer:

Explanation is given below.

Step-by-step explanation:

Given:

Number of Trumpets = 40

Number of tubas = 35

Carlee says, the ratio of trumpets to tubas = 40 : 35

Danny says, the ratio of trumpets to tubas = 8 : 7

To explain why the two ratios are equivalent.

Solution:

Equivalent ratios are all ratios which are equal to each other in their reduced to simplest form.

The ratio of trumpets to tubas can be given as = $\frac{40}{35}$

To reduce the ratio to its simplest form, we divide both numbers by their G.C.F.

The G.C.F. for 40 and 35 is 5.

So, we divide numerator and denominator by 5.

⇒ $\frac{40\div5}{35\div 5}$

⇒ $\frac{8}{7}$

Thus, the simplest ratio of trumpets to tubas can be given as = 8:7

This is why both Danny and Carlee are correct with the ratios of trumpets to tubas.

Carlee gave the direct ratio, while Danny gave the simplest ratio.
