Answer: a=4, b=-8, c=-3
Step-by-step explanation: This equation isn't in standard form. To get it there, subtract -3 from both sides. This gets you an equation of 4x^2-8x-3.
The standard form is ax^2+bx+c.
A is the number before x^2 (4). B is the number before x, and since it's subtracted it's negative (-8). C is the last number, and since it's subtracted it's negative (-3).
The answer is the function is not one to one
Answer:
28 ounces = 793.79 grams
28 ounces = 0.79 kilograms.
Step-by-step explanation:
What we know:
Acct. balance A (11)= $2,976.45
Pricipal=$1,963.45
Compounded (n)=quarterly (4)
rate=r
Compound interest formula: A (t)=p (1+r/n)^nt
What we need toi find:
If the interest compounds quarterly, what is the interest rate on the account? Find r.
A (t)=p (1+r/n)^nt
2976.45=1963.45 (1+r/4)^(4×11)
2976.45=1963.45 (1+r/4)^44
2976.45/1963.45=1963.45/1963.45 (1+r/4)^44
1.5159=(1+r/4)^44
(1.5159)^(1/44)=((1+r/4)^44)^(1/44)
1.0095=1+r/4
1.0095-1=1-1+r/4
.0095=r/4
.0095(4)=r/4 (4)
.038=r
Rate = 3.8%
Answer:
x=50 ∠BCX=65
Step-by-step explanation:
The angles is a triangle add up to 180 so
70+45+∠BCX=180 so
115+∠BCX=180 (subtract 115 from both sides)
∠BCX=65
A line adds up to 180
so 2x+15+65=180
so 2x+80=180 (subtract 80 from both sides)
2x=100 (divide by 2)
x=50
