Answer:
It becomes smaller
Step-by-step explanation:
bc you r just taking a fraction(part) of the bigger number, so it becomes smaller.
Answer:
6 1/4 cups of flour
Step-by-step explanation:
24/2 = 12
2.5/2 = 1.25
12 x 5 = 60
1.25 x 5 = 6.25 cups
For every 24 cookies Markes needs 2.5 cups of flour. So, for 12 cookies he needs half of that which is 1.25 cups. 12 is a fifth of 60, so we multiply 1.25 by 5 which gives us 6.25 cups of flour. :D
Given that the plane is at altitude of 1200m and the angle of depression is 28°, to calculate the distance between the the plane and the rock we assume that we a have right triangle whereby the distance of the plane form the ground is the height, the distance from plane to the rock is the hypotenuse and the remaining distance is the base:
thus
sin θ=opposite/hypotenuse
θ=28°
opposite=1200m
hypotenuse=h
thus
sin 28=1200/h
h=1200/sin 28
h=2556.065 m
Answer:
minimum
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Whether the function is maximum or minimum can be determined by consideration of the sign of the coefficient a
• If a > 0 then minimum
• If a < 0 then maximum
For y = - 4 + 3x² the value of a is 3 > 0
Hence y = - 4 + 3x² is a minimum
