Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC

Answer: a) Equation y= 20+ 1.50n.</h3><h3>b) Melia have $644 to spend on her 18th birthday.</h3>
Step-by-step explanation: We are given that Melia put $20 initially in piggy bank.
Each week amount added in piggy bank = $1.50.
Let us assume total number of weeks be n Melia added amount in piggy bank and get y amount after n weeks.
a) Therefore, total amount after n weeks = Initial amount + 1.50 times n weeks.
y= 20+ 1.50n.
b) On 18th birthday, there would be total 8 years after 10th birthday.
And in 8 years there would be 52 × 8 = 416 weeks.
So, in order to find the total amount after 8 years or 416 weeks, we need to plug n= 416 in the equation we got in a part.
Therefore,
y = 20+ 1.50(416)
y = 20 + 624 = 644.
<h3>Therefore, Melia have $644 to spend on her 18th birthday.</h3>
Answer:
Not an exponential function. The exponent is a constant.
Step-by-step explanation:
An exponential function has the variable in the exponent. This function raises the variable to a fixed power, so it is not an exponential function.
5x+1/7-2x-6/4>-4 equals x>-37/42
