Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = x² + 2x + 7 → (1)
y - 7 = x → (2)
Rearrange (2) expressing y in terms of x by adding 7 to both sides
y = x + 7 → (3)
Substitute y = x + 7 into (1)
x + 7 = x² + 2x + 7 ( subtract x + 7 from both sides )
0 = x² + x ← factor out x from each term
0 = x(x + 1)
Equate each factor to zero and solve for x
x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (3) for corresponding values of y
x = 0 → y = 0 + 7 = 7
x = - 1 → y = - 1 + 7 = 6
The solutions are
(- 1, 6 ) and (0, 7 )
I would need more information since you must use trig to find the value
I would need to know where they are located in order to find cos of H correctly
Hey there,
We know that area is the size of a surface
First of all, <span>To find the </span>area<span> of a rectangle, multiply the length by the width. In this question the length would be 90 meters and the width would be 45 meters.
</span>90 x 45 = Area
90 x 45 = 4050
<span>Area = 4050m</span>²
To find your probability of winning, you will convert the fraction 3/5 to a percent.
You can do this by dividing 3 and 5 to get 0.6 and then 60%, or you can create an equivalent fraction with a denominator of 100.
<u>3 </u> <u>60</u>
5 = 100
60%
You just take 100% and subtract the 24% that makes up 84. which gives you 76 and u just multiply that by 84.
