Answer:
yes
Step-by-step explanation:
yes
Answer:
1
Step-by-step explanation:
V= 1/3^r²h
V= (^r²h) ÷ 3
Cross multiply
3V = ^r²h
Divide both side by the coefficient of r²
3V ÷ (^h) = r²
Find the root of both side
r = square root of 3V ÷ (^h)
To find out if there is point where the graphs intersect simply plug in one equation for another,
y = 4x + 3
Y = -x^2 - 1.
4x + 3 = -x^2 - 1
Then solve
4x + 3 = -x^2 - 1
X^2 + 4x + 3 = -1
X^2 + 4x + 4 = 0.
(X+2)(x+2) = 0.
There is one solution X = -2. To solve for the y coordinate plug X = -2 to any of the above equations, easier for the first one.
Y = 4x + 3
Y = 4(-2) + 3
Y = -8 + 3
Y = -5.
Point - P(-2,-5). Plug these points in both original equations and if in each the left side is equal to the right, then that is the point of intersection. Basically the graph intersects once.
Answer:
A)Congruent by AAA
Step-by-step explanation:
It shows in the Given that all of the angles are congruent.
AAA stands for angle angle angle, meaning all the angles are congruent
hope this helps
The answer is A
i think so but i might be wrong
sorry if i am.
