Answer:

YR = 33.6 in.

Step-by-step explanation:

△DLZ∼△MYR

LZ / DZ = YR / MR

21/18 = YR / 28.8

7 / 6 = YR / 28.8

YR = 7 * 28.8 / 6

YR = 33.6

Let f(x) =[[x]], what is f(-5.2)

ANEK [815]

flooring a value, simply means, dropping it to the closest integer, so for the floor function or ⌊x⌋, that means

⌊ 2.5 ⌋ = 2

⌊ 2.00000001 ⌋ = 2

⌊ 2.999999999999⌋ = 2

⌊ -2.0000000001⌋ = -3

⌊ -2.999999999999⌋ = -3

let's recall that on the negative side of the number line, the farther from 0, the smaller, so -1,000,000 is a tiny number compared to the much larger -1.

⌊ -5.2 ⌋ = -6.

Answer:

1 11/24 tablespoons

Step-by-step explanation:

$1+1+1\frac{1}{3} +1\frac{1}{3} +1\frac{2}{3} +1\frac{2}{3} +1\frac{2}{3} +2=\\\\2+2\frac{2}{3} +3\frac{6}{3} +2=\\\\9\frac{8}{3} =\\\\11\frac{2}{3}$

There were 8 mugs in total so:

$11\frac{2}{3}$ ÷ 8=

$11\frac{2}{3} *\frac{1}{8} =\\\\\frac{35}{3} *\frac{1}{8} =\\\\\frac{35}{24} =\\\\1\frac{11}{24}$

A quadratic function has x-intercepts 2 and 6 and its vertex is (4, 8). What is the corresponding quadratic expression? A. 2x2 −

Goryan [66]

Given:

A quadratic function has x-intercepts 2 and 6 and its vertex is (4, 8).

To find:

The corresponding quadratic expression.

Solution:

If graph of a function intersect the x-axis at c, then (x-c) is a factor of the function.

A quadratic function has x-intercepts 2 and 6. It means (x-2) and (x-6) are two factors of the required quadratic function.

The function is defined as:

$P(x)=a(x-2)(x-6)$ ...(i)

Where, a is a constant.

The vertex of the quadratic function is (4,8). It means the point (4,8) will satisfy the function.

Substituting x=4 and P(x)=8 in (i).

$8=a(4-2)(4-6)$

$8=a(2)(-2)$

$8=-4a$

Divide both sides by -4.

$\dfrac{8}{-4}=a$

$-2=a$

Putting $a=-2$ in (i), we get

$P(x)=-2(x-2)(x-6)$

$P(x)=-2(x^2-6x-2x+12)$

$P(x)=-2(x^2-8x+12)$

$P(x)=-2x^2+16x-24$

Therefore, the correct option is B.
