Write an equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation y=−13x+4.

lilavasa [31]

Answer:

y = -13x + 55

Step-by-step explanation:

perpendicular formula : m1 × m2 = -1

y = -13x + 4

now we take the grafient of the equation which is 13 :

m × 13 = -1

m = -13

so now we hv a new gradient then we can find the equation use the formula y = mx + c :

m = -13 point = ( 4 , 3 )

sub them into the formula,

3 = -13 (4) + c

3 = -52 + c

3 + 52 = c

55 = c

c = 55

now we rewrite again the c and the m to become a complete equation : y = -13x + 55

What is the probability that the first marble is blue and the second marble is yellow?

Cloud [144]

Answer:

$\frac{1}{14}$

Step-by-step explanation:

First time drawing:

Total outcome is 8

Favorable outcome is 2

The probability that the first marble drawing in random is blue is

$\frac{2}{8}$ = $\frac{1}{4}$

Second time drawing (with no replacement):

Total outcome is 7 (8 - 1 = 7)

Favorable outcome is 2

The probability that the second marble drawing in random is yellow is

$\frac{2}{7}$

The probability that the first marble is blue and the second marble is yellow is $\frac{1}{4}$ × $\frac{2}{7}$ = $\frac{2}{28}$ = $\frac{1}{14}$

Find the area bounded by the curves x = 2y2 and x = 1 - y. Your work must include an integral in one variable.

Sedbober [7]

Answer:

Hello,

in order to simplify, i have taken the inverses functions

Step-by-step explanation:

$\int\limits^\frac{1}{2} _{-1} {(-2x^2-x+1)} \, dx \\\\=[\frac{-2x^3}{3} -\frac{x^2}{2} +x]^\frac{1}{2} _{-1}\\\\\\=\dfrac{-2-3+12}{24} -\dfrac{-5}{6} \\\\\boxed{=\dfrac{9}{8} =1.25}\\$
