-6m+13=0 (put all like terms together)
-6m=-13 (subtracted 13 from both sides to leave m alone)
m=2.17 (divided both sides by -6)
Answer:
$400
Step-by-step explanation:
1) we need to find area of trapezoid first
area of trap formula:( (b1+b2)/2)h
b1=5
b2=3
h=4
(5+3)/2=4
4*4=16
there are 16 square feet in thtat trapezoid
hence, 25*16= $400
the glass cost $400
The sphere. All the others are prisms.
Answer:
5/8
Step-by-step explanation:
Geometric mean is found by multiplying the n number of values and then taking the n-root.
To do this with these numbers, sqrt((9/16)*(25/36)) = (3/4)(5/6) = (1/4)(5/2)= 5/8
I hope this helps! :)
Answer:
3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, - 4) , thus
y = a(x - 2)² - 4
To find a substitute (3, - 1 ) into the equation
- 1 = a(3 - 2)² - 4 ( add 4 to both sides )
3 = a
Thus
y = 3(x - 2)2 - 4 ← equation in vertex form
= 3(x² - 4x + 4) + 4
= 3x² - 12x + 12 + 4
= 3x² - 12x + 16 ← equation in standard form
with coefficient of x² term = 3
