I’m sorry my answer was wrong
Answer:
C. (-5,0) and (3,0)
Step-by-step explanation:
y= x² + 2x-15
y = 0
x² + 2x-15 = 0
(x - 3) (x + 5) = 0
x = 3 or x = -5
Answer:
f(x)= -3x² - 12x - 5
Step-by-step explanation:
-3(x+2)² + 7
-3(x+2)(x+2) + 7
(-3x-6)(x+2) + 7
-3x² - 6x - 6x - 12 + 7
-3x² - 12x - 5
Answer:
cubic meter of clay will be used to create all the pyramids
Step-by-step explanation:
The remaining part of the question is given in the attached file
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids
Substituting the given values in above equation, we get -
cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids
cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid Cubic centimeter
The slope formula is y2-y1/ x2-x1 so after plugging it in it would be 2-3/5-4 and you will get your answer.
