50 POINTS QUICK Given that a­­b = x, evaluate the following:

1.) [tex]a^{2b}[/tex]
2.)[tex]a^{b+2}[/tex]

Answers

Answer:

2)The answer is x*a^2 because the equation is saying a^b*a^2. And if we knew that a^b = x, then the answer is x*a^2

Step-by-step explanation:

prove that the roots of x2+(1-k)x+k-3=0 are real for all real values of k​

Answers

The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

The equation is given as:

x^2 + (1 - k).x+k-3 = 0

For an equation to have real root, then the following must be true:

[tex]b^2 \ge 4ac[/tex]

In x^2 + (1 - k).x+k-3 = 0, we have:

a = 1

b = 1 - k

c = k - 3

So, we have:

[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]

Evaluate

[tex]1 - 2k + k^2 \ge 4k - 12[/tex]

Collect like terms

[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]

[tex]k^2 - 6k + 13 \ge 0[/tex]

Using a graphing calculator, the value of k is all real numbers

Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

How many cubes with the side lengths of 1/4 cm does it take to fill the prism?

Answers

9514 1404 393

Answer:

  224 cubes

Step-by-step explanation:

In terms of 1/4 cm cubes, the dimensions of the prism are ...

  (2 cm)/(1/4 cm/cube) = 8 cubes long

  (7/4 cm)/(1/4 cm/cube) = 7 cubes wide

  (1 cm)/(1/4 cm/cube) = 4 cubes high

The volume in 1/4-cm cubes is ...

  V = LWH = (8)(7)(4) = 224 . . . cubes

224 cubes are required to fill the volume.

if (-1 ,5 ) satisfies the equation 3x + Ky =7 then k =?

Answers

Answer:

k = 2

Step-by-step explanation:

3(-1) + k(5) = 7

-3 + 5k = 7

5k = 10

k = 2

The value of K in the equation 3x + Ky =7 is 2.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

Equation 3x + Ky =7.

And we have also given that (-1, 5) satisfies the equation.

That means,

(-1, 5) is a solution of the equation.

To find the value of K;

Substitute the value of x = -1 and y = 5

So,

3x + Ky =7,

3(-1) + K(5) =7

-3 + 5K = 7

5K = 10

K = 2

Therefore, the value of K is 2.

Answers

Answer:

y = - ( x + 2 )² + 14

Step-by-step explanation:

f(x) = ax² + bx + c

f(x) = a(x - h)² + k (where (h, k) are coordinates of the vertex.

h = - [tex]\frac{b}{2a}[/tex]

~~~~~~~~~~~~

f(x) = - x² - 4x + 10

a = - 1, b = - 4, c = 10

h = - [tex]\frac{-4}{2(-1)}[/tex] = - 2

k = - ( - 2)² - 4( - 2) + 10 = 14

Like all planets, the planet Venus orbits the Sun in periodic motion and simultaneously spins about its axis. Just as on Earth, the time to make one complete orbit (i.e., the period of orbit) is what defines a year. And the time to make one complete revolution about its axis (i.e., the period of rotation) is what defines a day. The period of orbit for the Earth is 365.25 days and the period of rotation is 24 hours (1.00 day). But when these same values for Venus are expressed relative to Earth, it is found that Venus has a period of orbit of 225 days and a period of rotation of 243 days.
