Step-by-step explanation:
Answer:
y = 33.94 mm
x = 19.80 mm
Step-by-step explanation:
Because AC = CB, then ∠ABC = 45°
cos ∠ABC = 24/y
cos 45° = 0.7071 = 24/y
y = 33.94 mm
EF/BC = x/y
14/24 = x/33.94
24x = 475.16
x = 19.80 mm
Answer:
"all real numbers."
Step-by-step explanation:
Subtract 13 from both sides, obtaining -5x = -5x.
This result is true for all x, so the solution set is "all real numbers."
Hello :
<span> f(x) = -5x² +x+1
</span>a = -5 b = 1 c = 1
the vertex is the point A(-b/2a ; f(-b/2a) )
-b/2a = (-1/-10) = 1/10 = 0.1
f(1/10) = -5(1/10)²+(1/10)+1 =21/20 = 1.05
<span>4 the square root of 2 + 7 the square root of 2 - 3 the square root of 2
= 4</span>√2 + 7√2 - 3√2
= √2(4 + 7 - 3)
= √2 (8)
= 8√2
Answer
8√2
