Answer:
the correct answer is the last one to the right side
Answer:
3 months
Step-by-step explanation:
t^3 - 10t^2 + 33t - 36
3t^2 -20t + 33 = 0
(3t-11)(t-3) = 0
t = 3 or t=11/3
Answer: it’s 12
Step-by-step explanation:
We are given with the following value:
AB = BC =90 cm
∠B =25°
∠D=90°
Solving the ∠C:
180 ° = (∠B/2) + ∠D +∠C
180° = (25°/2) + 90° + ∠C
180° - 12.5° -90° = ∠C
∠C = 77.5°
Solving for length in mD:
sin 77.5° = mD/90
mD = 90 sin77.5°
mD = 87.87
Solving for mDC:
cos 77.5 = mDC/90
mDC = 90 cos 77.5°
mDC = 19.48
Area = 1/2 * Base * Height
Area = 1/2 * 19.48*87.87
Area = 855.834
The total area of triangular pennant = 2 x 855.834 = 1,711.67 cm².
The area is 1,711.67 cm².
Answer:
x= -1, -9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/4x2+5/2x+21/4=3
Step 2: Subtract 3 from both sides.
1/4x2+5/2x+21/4−3=3−3
1/4x2+5/2x+9/4=0
For this equation: a=0.25, b=2.5, c=2.25
0.25x2+2.5x+2.25=0
Step 3: Use quadratic formula with a=0.25, b=2.5, c=2.25.
x=−b±√b2−4ac/2a
x=−(2.5)±√(2.5)2−4(0.25)(2.25)/2(0.25)
x=−2.5±√4/0.5
x=−1,−9
