Algebra 1:Write an algebraic expression for 91 more than the square of a number

Bumek [7]

Give the number a name. You can call it anything. I'll call it ' G '.

The square of the number is G² .

91 more than that is G² + 91 .

Helppp im stuck :( Hope you guys help me

andriy [413]

Answer:

$y=-\dfrac{1}{2}x+2$

Step-by-step explanation:

Define two points on the line:

$\textsf{let}\:(x_1,y_1)=(0,2)$

$\textsf{let}\:(x_2,y_2)=(4,0)$

Use the slope formula and the defined points to find the slope:

$\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-2}{4-0}=-\dfrac{1}{2}$

Substitute the found slope and one of the points into the point-slope form of a linear equation:

$\implies y-y_1=m(x-x_1)$

$\implies y-2=-\dfrac{1}{2}(x-0)$

Simplify:

$\implies y-2=-\dfrac{1}{2}x$

$\implies y=-\dfrac{1}{2}x+2$

Hello,

$\lim_{x \to 0}\dfrac{ \sqrt{x+25}-5}{x}\\\\$

$=\lim_{x \to 0}\dfrac{(\sqrt{x+25}-5)*(\sqrt{x+25}+5)}{x*(\sqrt{x+25}+5)}\\\\$

$=\lim_{x \to 0}\dfrac{x+25-25)}{x*(\sqrt{x+25}+5)}\\\\$

$=\dfrac{1}{10}$

Find tan 0 if csc 0 = -√5/2 is in the third quadrant. A. 1/2 B.-2 C.-1/2 D. 2

MakcuM [25]

Answer:

D. 2

Step-by-step explanation:

soh cah toa rule

sine equals opposite over hypotenuse,

cosine equals adjacent over hypotenuse, and

tangent equals opposite over adjacent

csc is 1/sin which is hypotenuse over opposite

if csc is -√5/2 then

hypotenuse is -√5

opposite is 2

3rd quadrant on a graph is bottom left

both x and y values are negative

hypotenuse means its a triangle

pythagorean theorem

a^2 + b^2 = c^2

a^2 + 2^2 = (-√5)^2

a^2 + 4 = 5

a = 1 = adjacent

tangent equals opposite over adjacent

tan is 2 / 1 which is 2

third quadrant means it's still positive

because tan is positive in quadrant 3
