Answer:
x=-15
Step-by-step explanation:
Change 2 to a denominator of 4 2x4=8
1/12x+8/4=3/4 (take away 8/4)
1/12x=-5/4 ( 5multiply by 12)
x=-60/4 (divided by 3)
x=-15
Answer:
g(x) = 86·1.011055^x
Step-by-step explanation:
So we don't confuse ourselves, we'll call the growth function by day g(x). If x is to represent days, then x/7 represents weeks, and we can write ...
g(x) = f(x/7) = 86·1.08^(x/7)
g(x) = 86·(1.08^(1/7))^x
g(x) = 86·1.011055^x
Answer:
- 65 -3x = 55 -2.5x
- 20 periods
- $5
Step-by-step explanation:
The value of the first card starts at $65 and decreases by $3 for each of x periods. Its value is ...
65 -3x
The value of the second card starts at $55 and decreases by $2.50 for each of x periods. Its value is ...
55 -2.5x
The equation that can be used to find x that makes the values equal is ...
65 -3x = 55 -2.5x
__
The solution can be found by adding 3x-55 to both sides of this equation.
10 = 0.5x
Multiplying by 2 gives ...
20 = x
After 20 30-day periods. the cards will have the same value.
__
The value after 20 periods is ...
65 -3×20 = 65 -60 = 5
Both cards will have a value of $5 when they have the same value.
Hey there! I'm happy to help!
To find this other side given an angle and a side, we will use a trigonometric function. The three basic ones are sine, cosine, and tangent. You can remember these and what what they are using the mnemonic "soh cah toa".
SOH: Sine= Opposite/Hypotenuse
CAH: Cosine= Adjacent/Hypotenuse
TOA: Tangent= Opposite/Adjacent
We see that the sides involved are the opposite and hypotenuse.
Therefore, we can write this equation.
sin40= w/28
We multiply both sides by 28 to isolate the w.
28×sin40=w
Now, we find the sine of 40 on our calculator and then we multiply it by 28.
w≈18
Therefore, the answer is 18 cm.
I hope that this helps! Have a wonderful day!
