X+y=5 x^y+y^x=17 solve for the value of y and x

1 answer:

7 0

X = 2
y = 3 

2 + 3 = 5 
2³ + 3² = 17 

------------------- 

BUT: 

x + y = 5 
x^y + y^ x = 17 

y = 5 - x

What is the area of a cone that has a diameter of 45ft. and the height of the cone is 96 ft.

jarptica [38.1K]

The formula for area of a cone is A=πr(r+√h²+r²). The radius is half the diameter, so 22.5.

Plug our numbers into the formula.

A=π22.5(22.5+√96²+22.5²)

the answer is 8560.16

A person invested $420 in an account growing at a rate allowing the money to double

AURORKA [14]

Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t log(2)

divide by log 2

1.19264508= 10 /t

10(1.19264508)

11.926450779=t
