How do i evaluate an expression with a given variable

1 answer:

8 0

To evaluate an expression with a given variable means to replace the number in the place of the variable, and then solve to find what the expression equals.
Example would be: x + 3 and x = 4
x + 3
4+3 = 7
7 is the value of the expression now.

Answer:

A. $\cos \: x - 4 \: \cos \: x \: { \sin}^{2}x$ (first option)

Step-by-step explanation:

➡️ $\cos(x + 2x)$

➡️ $\cos \: x \: { \cos}^{2} x - \sin \: x \: { \sin }^{2} x$

➡️ $\cos \: x(1 - 2 \sin^{2}x) - \sin \: x \times 2 \sin(x) \cos(x)$

➡️ $\cos(x) - 2 \sin^{2} x \cos(x) - 2 \sin^{2} x \cos(x)$

➡️ $\cos(x) - 4 \cos(x) \sin^{2} x$

Find the values of y for which the distance between the point p2,-3 and q 10, y is 10 units

lina2011 [118]

Answer:

y = - 9, y = 3

Step-by-step explanation:

Calculate distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (10, y)

d = $\sqrt{(10-2)^2+(y+3)^2}$

= $\sqrt{8^2+(y+3)^2}$

Given distance between points is 10, then

$\sqrt{64 +(y+3)^2}$ = 10 ( square both sides )

64 + (y + 3)² = 100 ( subtract 64 from both sides )

(y + 3)² = 36 ( take the square root of both sides )

y + 3 = ± $\sqrt{36}$ = ± 6 ( subtract 3 from both sides )

y = - 3 ± 6 , thus

y = - 3 - 6 = - 9

y = - 3 + 6 = 3
