<u><em>60 inches is correct answer.</em></u> First you had to used their volume=length*width* height to used their formula of surface area. You had to go to 5*4=20, and 20*3=60, <u><em>60 inches is the correct answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
Answer:
Cartesian Equation: y = √(1 - x^2)
Graph: Second one
Step-by-step explanation:
x^2 = sin^2(θ/2),
y^2 = cos^2(θ/2),
According to that theory, by the circle equation, x^2 + y^2 = 1^2.
When θ = -π, x = sin(-π/2) = - 1, and y = cos(-π/2) = 0
When θ = π, x = sin(π/2) = 1, and y = cos(π/2) = 0
The radius is 1 in this case, (x^2 + y^2 = r^2 -> x^2 + y^2 = 1^2 -> x^2 + y^2 = 1) as the semicircle ranges from (- 1, 0) to (1,0). Therefore your graph is the second one;
When theta = 0, x = sin 0 = 0, and y = cos 0 = 1, so the semicircle passes through (0, 1). To determine the equation, let's simply isolate "y" in the equation x^2 + y^2 = 1^2,
In Cartesian form, the equation is y = √(1 - x^2)
Answer:
x = 3; y = 8
Step-by-step explanation:
Sides KI and KE are congruent.
4x = 12
x = 3
Sides IT and ET are congruent.
3y - 4 = 20
3y = 24
y = 8
Answer: x = 3; y = 8
Let no of blueberries be x
2 x bluberries = total raspberries
So raspberries = 2x
Cherries= 4 x raspberries so
Cherries = 8 x
Grapes = 3x cherries so
Grapes = 24x
Total fruit is equal to
X+2x+24x+8x=280
35x=280
Therefore X= 280/35=8
No of cherries in the salad
=8x
=8(8)
=64 cherries in total
Hope this helped and sorry I used shortcuts
Hope u understand
