Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Line 1 = 0
Line 2 = undefined
Explanation:
Line 1 = rise/run = 0
Line 2 = rise/run = 0/0 = undefined
Answer:
66
Explanation:
Volume for any prism=base area*height
The base is a triangle and the formula to find the area of a triangle is Area=(base*height)/2. Once we input the values it would look like:
Area=(4*3)/2
A=12/2
A=6
In this case, the height of the prism would be 11. Now we input our values for finding the volume:
Volume for any prism=base area*height
Volume=6*11
Volume=66
I hope this helps! Please comment if you have any questions.
Câu trả lời:
0,7
Giải thích từng bước:
Xác suất để một sự kiện xảy ra = 0,3
Cho sự kiện = A
P (A) = 0,3
Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;
P (A ') = 1 - P (A)
Vì thế,
P (A ') = 1 - 0,3 = 0,7
