Answer:

288

Step-by-step explanation:

In this expression, you can solve it by first evaluating the exponents then you can add all of the terms together.

1^1 = 1
2^2 = 4
3^3 = 27
4^4 = 256

Add all of the numbers together.

1 + 4 + 27 + 256 = 288

We know that 1^1 is 1.

We know that 2^2=4.

We know that 3^3=27.

We know that 4^4=16^2=256.

So, adding these up, we get 1+4+27+256=5+27+256=32+256=288.

The ratio x:10 is equilvalent to 9:6. What is the value of x

Troyanec [42]

Answer: x=20/3=6.67

Step-by-step explanation:

To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.

-----------------------------------------------------------------------------

Given

x:10=9:6

Cross Multiply

9·x=6·10

9x=60

Divide 9 on both sides

9x/9=60/9

x=20/3=6.67

Hope this helps!! :)

Find the value of a square + b square when a+b = 8 and ab = 10

Ne4ueva [31]

As we know,

$\boxed{ \boxed{(a + b) {}^{2} = {a}^{2} + {b}^{2} + 2ab}}$

now, let's plug the given values to find a² + b²

$(8) {}^{2} = {a}^{2} + {b}^{2} + (2 \times 10)$

$64 = {a}^{2} + {b}^{2} + 20$

${a}^{2} + {b}^{2} = 64 - 20$

$a {}^{2} + b {}^{2} = 44$

Willie changes the quadratic function f(x)=x2?6x+14 to vertex form f(x)=a(x?h)2+k. If Willie does this correctly, what is the va

andrew11 [14]

Answer:

The value of k is 5.

Step-by-step explanation:

Since we know we can convert function's quadratic form to vertex form by completing the square.

f(x)=x2?6x+14

We will add and subtract 9 to our equation in order to complete the square.

$1(x^{2} ?6x+9)-9+14$

Upon completing the square and combining like terms we will get,

$1(x?3)^{2} +5$

Upon comparing Willie's vertex form with our expression we can see that k is 5.

Therefore, the value of k is 5.
