Answer:
(1) 20%
Step-by-step explanation:
→ Find the difference in price
200 - 160 = 40
→ Divide difference by original price
40 ÷ 200 = 0.2
→ Multiply the answer by 100
0.2 × 100 = 20%
Answer:
1 and 5
Step-by-step explanation:
So basically corresponding angles are the angles which lie on the same line of the transversal
And also one of them will be an interior angle and the other a exterior angle
Answer:
b = 
Step-by-step explanation:
Divide both sides by dt, so it cancels out.


The height attained by the arrow is modelled as,

Given that the initial height is 20 ft and the initial velocity is 179 ft per second,

Substitute the values,

When the arrow hits the ground its height will become zero,

Applying the quadratic formula,
![\begin{gathered} t=\frac{-(-179)\pm\sqrt[]{(-179)^2-4(-16)(20)}}{2(-16)} \\ t=\frac{179\pm\sqrt[]{33321}}{-32} \\ t=\frac{179\pm182.54}{-32} \\ t=\frac{179+182.54}{-32},t=\frac{179-182.54}{-32} \\ t=-11.298,t=0.1106 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20t%3D%5Cfrac%7B-%28-179%29%5Cpm%5Csqrt%5B%5D%7B%28-179%29%5E2-4%28-16%29%2820%29%7D%7D%7B2%28-16%29%7D%20%5C%5C%20t%3D%5Cfrac%7B179%5Cpm%5Csqrt%5B%5D%7B33321%7D%7D%7B-32%7D%20%5C%5C%20t%3D%5Cfrac%7B179%5Cpm182.54%7D%7B-32%7D%20%5C%5C%20t%3D%5Cfrac%7B179%2B182.54%7D%7B-32%7D%2Ct%3D%5Cfrac%7B179-182.54%7D%7B-32%7D%20%5C%5C%20t%3D-11.298%2Ct%3D0.1106%20%5Cend%7Bgathered%7D)
Since time cannot be negative, we have to neglect the negative value.
Thus, it can be concluded that the arrow will hit the ground after 0.1106 seconds approximately.
Answer:
c = 17
Step-by-step explanation:
a^2 + b^2 = c^2
= 8*8 + 15*15
= 64 + 225
= 289
= 289 SQUARED
= 17
