X^2+1/2x+____=2 + ____

Answer:  x^2+\frac{1}{2}x+\frac{1}{16}=2 +\frac{1}{16}

Step-by-step explanation:

Given the following Quadratic equation:

x^2+\frac{1}{2}x=2 +

You can change its formed by Completing the square.

In order to do Complete the square, you can follow these steps:

1. You can identify that:

b=\frac{1}{2}

2. Then, you can find (\frac{b}{2})^2. This is:

(\frac{\frac{1}{2}}{2})^2=(\frac{1}{4})^2=\frac{1}{16}

3. Now you must add \frac{1}{16} to both sides of the Quadratic equation in order to keep the balance. Then:

x^2+\frac{1}{2}x+\frac{1}{16}=2 +\frac{1}{16}

4. Finally, simplifying by actoring and adding the like terms, you get:

(x+\frac{1}{4})^2=\frac{9}{4}

Which inequality describes all the solutions to 5(3 − x) < −2x + 6?
Marrrta [24]

Given:

The inequality is

5(3-x)

To find:

The inequality that solution describes all the solutions to the given inequality.

Solution:

We have,

5(3-x)

Using distributive property, we get

5(3)+5(-x)

15-5x

15-6

9

Divide both sides by 3.

\dfrac{9}{3}

3

It can be written as

x>3

Therefore, the value of x is greater than 3. So, the required inequality is either x>3 or 3.

A bag contains 10 pounds of dog food.

A family feeds their dogs 0.85 pound of dog food a day so cin seven day the dog eats (0.85 x 7) = 5.95 pounds

so, <span>dog food is left in the bag after 7 days is </span>(10-5.95) = 4.05 pounds

A golfer attempts to hit a golf ball over a valley from a platform above the groun
leonid [27]

Answer: NO

Step-by-step explanation:

The functions that models the height of the ball is given as

h(t) = -5t2 + 40t + 100

Where

a = -5, b = 40, c = 100

The time the ball will reach the maximum height will be the vertex of the parabola. At the line of symmetry, the time t will be:

t = -b/2a

Substitute b and a into the formula above.

t = - 40 / -5 = 8

Substitute 8 for t in the function f(t)

h(t) = - 5(8)^2 + 40(8) + 100

h(t) = -5(64) + 40(8) + 100

Open the bracket

h(t) = -320 + 320 + 100

h(t) = 100

The maximum height of the ball is 100m

Given that the power lines is 185 metres above the ground. The golf ball will therefore not hit power lines because the maximum height the ball can go is 100 metres

Can someone explain how to do #3?
dsp73

\displaysyle (\sqrt 2)^{3}=(2^{\frac{1}{2}})^3=2^{\frac{1}{2} \cdot 3}=2^{\frac{3}{2}}=\sqrt {2^3}=\sqrt 8

√8 is between 2 and 3, because 2²=4<8, but 3²=9>8. Also, our value is closer to 3 than to 2, so it is more than 2.5 and we have C and D options left.

Among these two numbers we find the one which is closer to √8.

C. 27=√729 ⇒ 2.7=√7.29

D. 28=√784 ⇒ <u>2.8=√7.84</u>

Hence our answer is D) 2.8
