Answer:
11 1/5
Step-by-step explanation:
3 1/5 ÷ 2/7 =
16/5 ÷ 2/7 =
KCF (Keep, Change, Flip)
Keep 16/5
Change ÷ to ×
Flip 2/7 to 7/2
16/5 × 7/2
16 x 7 = 112
5 x 2 = 10
112/10
11 2/10
11 1/5
Hope that helps :)
To solve this problem you must apply the proccedure shown below:
1. You have that the the <span>archway is modeled by the equation y=-2x^2+8x and the angle mentioned in the problem is defined by the equation x−2.23y+10.34=0.
</span>
2. Therefore, you must susbtitute y=-2x^2+8x into x−2.23y+10.34=0, as below:
x−2.23(-2x^2+8x)+10.34=0
3. When you apply the distributive property, you obtain:
x−2.23(-2x^2+8x)+10.34=0
x+4.46x^2-17.84x+10.34=0
4.46x^2-16.84x+10.34=0
4. When you solve the quadratic equation, you obtain:
x=3 units
Therefore, the answer is the option D: D. 3 units.
Answer: <em>D. </em><em>P, Q and R.</em>
Step-by-step explanation:
<em>The vertices of the triangle PQR - it is P, Q and R.</em>
Answer:
A
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
=
- 
Since both fractions have a common denominator of 3x, then subtract the numerators leaving the denominator, that is the numerators simplified
2x + 6 - (
- 8)
= 2x + 6 -
+ 8 = 2x -
+ 14
Hence
f(x) - g(x)
=
→ A
