Answer:
BC = 1.71
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
α = 70°
a: adjacent = BC
h: hypotenuse = 5
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
we look at which meets those data between the sine, cosine and tangent
is the cosine
cos α = a/h
Now we replace the values and solve
cos 70 = a/5
0.34202 = a/5
0.34202 * 5 = a
1.7101 = a
round to the neares hundredth
a = 1.7101 = 1.71
BC = 1.71
Answer:
29m+37?
Step-by-step explanation:
<em>Pemdas</em>
5m+3(8m+7)+4^2
Parentheses first: 5m+24m+21+4^2
Exponents next: 5m+24m+21+16
No multiplication or division so addition is last:
29m+37
These two can't add together because one has a variable.
Answer:
Step-by-step explanation:
<u>Given functions:</u>
- f (x) = 2x + 2
- g (x) = 3x – 1
<u>To find:</u>
<u>Solution</u>
- (f/g)(x) = f(x)/g(x) = (2x + 2) / (3x - 1)
- (f/g)(2) = (2*2 + 2) / (3*2 - 1) = 6/5 = 1.2
Yes it is a polynomial .
The degree of polynomial is 4 and there is no power as a fraction or negative integer
Answer:
d. 14
Step-by-step explanation:
- 3(2) = 3 × 2 = 6
- Plug 6 in: 12 + {10 ÷ [11 - 6]}
- 11 - 6 = 5
- Plug 5 in: 12 + {10 ÷ 5}
- 10 ÷ 5 = 2
- Plug 2 in: 12 + 2
- 12 + 2 = 14
I hope this helps!
