Answer:
For t = 0.33 s, H = 14.0976 feet;
For t = 3 s, H = 0 feet;
For t = 16 s, H = -3328 feet;
For t = 48 s, H = -34560 feet.
Step-by-step explanation:
Assuming there's a typo on the problem and it wishes to determine the distance traveled by the ball in the given times instead of the time, we can solve it as shown below:
For t = 0.33 s:
For t = 3 s:
For t = 16 s:
For t = 48 s:
Step-by-step explanation:
Multiply everything in the parenthesis.
24. (2xy)( -4x²) + (6x)(6x²y)
---> -8x³y + 36x³y
= 28x³y
25. (2ab²)(4a²b³) - (10a³b)(6b⁴)
---> 8a³b^5 - 60a³b^5
= -52a³b^5
Sorry, i cant turn the 5 into an exponent on my phone lol. but i hope this helps.
Answer:
m<ADB=70°
m<ADC=110°
m<DAC=45°
Step-by-step explanation:
<ADB=<ABD(being isosceles triangle: AD=AB)
<ABD+<ADB+<DAB=180°(sum of the angle of triangle is 180°)
2<ADB+40°=180°(<ADB=<ABD and <DAB=40°)
2<ADB=140°
<ADB=70°
<ADB+<ADC=180°(being straight angle)
70°+<ADC=180°
<ADC=110°
<ADC+<ACD+<DAC=180°( sum of the angle of triangle is 180°)
110°+25°+<DAC=180°
<DAC=45°
Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.
