<em>Answer</em>
= 11
<em>Explanation</em>
f(x) = x² + 3x- 7
To get the value of f(x) when x = 3, we substitute x with 3 in the function f(x).
f(x) = x² + 3x- 7
= 3² + (3×3) -7
= 9 + 9 - 7
= 11
Answer:
i think 4 th option
if u want to verify just substitute (4,-2)
Answer:
1434.375
Step-by-step explanation:
If you multiply 1,800 by 25% you get 1,350
you take 1,350 and add 6.25% because the 6.25% is the tax.
Then you will get 1434.37 or 1434.40
Answer:
cos M = 38 / 63
Step-by-step explanation:
SOH - CAH - TOA
is how I remember the calculations,
S - sin
C - cos
T - tan
(o = opposite side ; a = adjacent side ; h = hypotenuse)
SOH would be sin = opposite/hypotenuse
CAH means cos = adjacent / hypotenuse
Okay, so looking at the angle M, we know the hypotenuse [63] and the adjacent value [38]
From this, (only having H and A), we can only find the cos of M
(without finding additional numbers, which we could do with the Pythagorean theorem)
So, the cos of M is adjacent/hypotenuse
cos M = 38 / 63
(I didn't try to find other measurements of the triangle here because the most simple measurements [that were already there] worked/was an option)
