The sum of three numbers is 3068.Two of the numbers are 1266 and 1755,find the third number<br><br>

ratelena [41]

Answer:

The third number is 47.

Step-by-step explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

$\displaystyle{x + y + z = 3068}$

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

$\displaystyle{1266 + 1755 + z = 3068}$

Find the third number - solve for z-variable:

$\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}$

Therefore, the third number is 47.

Segment PE has endpoints P(-4,4) and E(0,-4). Find the coordinates of point Q such that PQ:QE is 1:3. Enter the coordinates belo

Natalka [10]

Answer:

(-3, 2)

Step-by-step explanation:

Given that point Q, partitions segment PE, such that PQ:QE is 1:3, coordinates of point Q is found using the formula below:

$x = \frac{mx_2 + nx_1}{m + n}$

$y = \frac{my_2 + ny_1}{m + n}$

Where,

$P(-4, 4) = (x_1, y_1)$

$E(0, -4) = (x_2, y_2)$

$m = 1, n = 3$

Plug in the necessary values to find x and y coordinates for point Q as follows:

$x = \frac{mx_2 + nx_1}{m + n}$

$x = \frac{1(0) + 3(-4)}{1 + 3}$

$x = \frac{0 - 12}{4}$

$x = \frac{-12}{4}$

$x = -3$

$y = \frac{my_2 + ny_1}{m + n}$

$y = \frac{1(-4) + 3(4)}{1 + 3}$

$y = \frac{-4 + 12}{4}$

$y = \frac{8}{4}$

$y = 2$

The coordinates of the point Q are (-3, 2))

Simplify the expresion <br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B3.%20%5Csqrt%5B4%5D%7B432%7D%20%7D%20" id="TexF

Bond [772]

$\sqrt[4]{3. \sqrt[4]{432}}$
= $\sqrt[4]{3. \sqrt[4]{2^4.3^3} }$
= $\sqrt[4]{3.2.3^\frac{3}{4}}$
= $3^\frac{1}{4}.2^\frac{1}{4}.3^\frac{3}{16}$
= $3^\frac{7}{16}.2^\frac{1}{4}$
