Answer:
- a = -25: -555
- a = 1: 69
- a = 10: -30
Step-by-step explanation:
Put the value where "a" is in the expression and do the arithmetic.
- For a = -25: 70 - (-25)² = 70 - 625 = -555
- For a = 1: 70 - (1)² = 70 - 1 = 69
- For a = 10: 70 - (10)² = 70 - 100 = -30

If you're unsure of your own arithmetic skills, you can always use a calculator.
The trigonometric identity states that the sum of the square of cosine and sin is equal to 1. In this case, the identity is tried to rearrange and tried to verify if the statement above is true.
<span>Square root 1 minus cosine squared theta = −sin Θ
This is only true in angles tried such as (360-45) or (270-45). hence </span><span> Θ should be in quadrant III and IV only</span>

Answer: $245.01
Step-by-step explanation:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$200 , r=7% , n=1 and t=3 years
After plugging the given information we have
A=200(1+0.071)1⋅3=200⋅1.073=200⋅1.225043=245.01
Hope this helps, give me brainliest
I think you mean, find the equation from the quadratic formula solution.
10x^2 -x +9 = 0
a=10 b=-1 c=9
x = --1 +-sq root(1 - 4*10*9) / 2*10
x = 1 +-sq root(1 -360) / 20
x = 1 +-sq root( -359) / 20
