For the equation y - 3 = -2(x + 1) the line has a slope of -2 and
contains what point
Answers
Answer:
(0, -2) --> Y-Intercept
Step-by-step explanation:
y - 3 = -2( x + 1 )
y - 3 = -2x - 2
y= -2x -2
Y-Intercept = (0,y)
= (0, -2)

A quarter falls off a building that is 144
feet tall. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is
time in seconds and h(t) is height in
feet, how many seconds will it take for
the quarter to hit the ground?
Answers
Answer:
3 seconds
Step-by-step explanation:
Initial height = 144 feet
t = Time taken
The equation of the height from the ground is
[tex]h(t)=-16t^2+\text{Initial height}[/tex]
The time taken to reach the ground is needed. Here the ground is taken as reference so [tex]h(t)=0[/tex]
[tex]0=-16t^2+144\\\Rightarrow -144=-16t^2\\\Rightarrow t=\sqrt{\dfrac{144}{16}}\\\Rightarrow t=3\ \text{s}[/tex]
So, time taken by the quarter to reach the ground is 3 seconds.

AO² = BO² +BA²
BO² = AO² -BA² = 17² -15² = 289 -225 = 64
BO = CO = √64 = 8

What is the area of a square if the half of the diagonal is 6
Answers
Answer:
72
Step-by-step explanation:
Cut the square into two equal triangles along the diagonal
You know that half of the diagonal is 6 so multiply that by 2 to get 12 which is the hypotenuse of your triangles
Then use the pythagorean theorem to solve for the sides
a^2 + b^2 = 12^2
a^2 + b^2 = 144
Since the original shape was a square both sides a and b are equal
a^2 = b^2
a^2 + a^2 = 144
2a^2 = 144
a^2 = 144/2
a^2 = 72
a = [tex]\sqrt{72}[/tex]
Since a = b then a = [tex]\sqrt{72}[/tex] =b
Multiply both sides a and b to get the area of the square
[tex]\sqrt{72}[/tex] * [tex]\sqrt{72}[/tex] = 72

35 female albino rats
11 female spotted rats
Total rats = 23+21+35+11 =90

After drawing first rat , total rats remained = 89
[tex]P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}[/tex]
