Nice, already in vertex form
y=a(x-h)^2+k
(h,k) is vertex
therfor since (-3,6) is vertex
we are looking for something like
y=a(x-(-3))^2+6 simplified to
y=a(x+3)^2+6
A is ansre
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x -3. What is the point slope form of the equation for this line?
we have
This is the equation of the line in slope intercept form
where
the slope is 
the y-intercept is 
Remember that
The equation of the line in point-slope form is equal to
we have
substitute
Answer:
( B.) 6, 1, -2 , -4
Step-by-step explanation:
A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.
-2+6y+m-2y+8-4m
Now we have to find the numbers that have a variable next to it
which are 6,m,-2, and -4
(If you are wondering that why m is a coefficient its because it is also known as 1m)
Final answer = 6, 1, -2 , -4
Hope this helps!
Answer:
B.) 54π units²
Step-by-step explanation:
First, we need to find the height of the cone. We can do this using the Pythagreom Theorem.
a² + b² = c² <----- Pythagreom Theorem
3² + b² = 15² <----- Insert side lengths
9 + b² = 225 <----- Solve 3² and 15²
b² = 216 <----- Subtract 9 from both sides
b = 14.7 units <---- Take square root of 216
Now, we can use the surface area of a right cone equation to find the final answer.
r = 3 units
h = 14.7 units
SA = πr(r + √(h² + r²)) <----- Surface Area equation
SA = π(3)(3 + √(14.7² + 3²)) <----- Insert values
SA = π(3)(3 + √(216 + 9)) <----- Solve 14.7² and 3²
SA = π(3)(3 + √225) <----- Add 216 and 9
SA = π(3)(3 + 15) <----- Take square root of 225
SA = π(3)(18) <----- Add 3 and 15
SA = 54π units² <----- Multiply 3 and 18
Answer:
i think bc they have the same angles. (angles are like the corners of it)
