Well... -5+12 you gotta add that first and look for the biggest number that's when you can decide whether the answer is - or + so -5+12= 7 then you add 7+10 which is 17 and then 17-(-7) WAIT (did you know that when a negative sign is besides a subtraction sign you change the subtraction sign for a + and the number is not gonna be negative and it changes into a positive so 17 -(-7) {17+7}= 24 if you doubt use a calculator! HOPE I HELPED! And I was really bad about this too, I just understood today. LOL

Write the exponential equation for this scenario. Mike buys a car for $45,000.00. The cars value depreciates (loses value) at a
gladu [14]

Answer:

A=45000(0.82)^t

Step-by-step explanation:

Given data

P= 45,000

rate= 18%

Recall the expression for the compound interest

A=P(1+r)^t

Since we are talking of depreciation

A=P(1-r)^t

Substitute

A=45000(1-0.18)^t\\\\A=45000(0.82)^t

Hence the exponential function is

A=45000(0.82)^t

WILL GIVE BRAINLIEST ANSWER TO WHOEVER ANSWERS FIRST AND CORRECT PLEASE EXPLAIN WHY YOU ARE CORRECT
Sholpan [36]

Answer:

In a typical kite as shown in picture, it is symmetric around PQ and PQ is perpendicular with RN.

=> Two right triangles PNT and PRT are congruent.

=> angle PRT = angle PNT = 34 deg

=> angle RPT = 90 - angle PRT = 90 - 34 = 56 deg

=> Option A is correct.

Hope this helps!
