Answer: 34 and 17 are two numbers created from the given digits whose product is estimated to be about 600.
Step-by-step explanation:
Let 34 and 17 are two whole numbers created from the given digits.
Case 1) If we multiply 34 and 17 then 34×17=578 if we rounding up to the nearest hundreds we will get 600.
Case 2) If we rounding up the whole numbers before multiplication as
estimate of 34 to the nearest ten is 30 and 17 to the nearest ten is 20
Then the product becomes 30×20=600.
So by both the ways 34 and 17 can be used for estimated product to be 600.
30 x 20
600
Also, 34 x 17 = 578, which rounds to 600
The answer is 34 and 17

Answer:
407 m
Step-by-step explanation:
Refer the attached figure
Karla spots a parked car on the ground at an angle of depression of 30° i.e. ∠BDP = 30°
Now the balloon rises 50 meters.i.e. AB = 50 m
So, the angle of depression to the car is 35 degrees. i.e.∠ADP = 35°
Let DP be the distance of the car prom point P
Let BP be x
In ΔBDP
--1
In ΔADP
--2
So, equating 1 and 2
Substitute the value of x in 1
Hence the car is at a distance of approximately 407 m from point P
Triangle #1.
X = Hor. side = dist. from P to the car.
Yi = Ver. side.
A = 30o.
Triangle #2.
X = Hor. side = Dist. from P to the car.
Y2 = Y1+50 = Ver. side.
A = 35o.
Use aw of Sines.
sin30/Y1 = sin35/(Y1+50).
Cross multiply:
(Y1+50)sin30 = Y1*sin35
Y1/2+25 = 0.574Y1
Multiply both sides by 2:
Y1+50 = 1.148Y1
1.148Y1-Y1 = 50
0.148Y1 = 50
Y1 = 337.8 m.
tan30 = Y1/X = 337.8/X
X = 337.8/tan30 = 585 m. 714 feet away hope that helps if not tell me.

Answer:
y = 7 - 2x
Step-by-step explanation:
Start with the equation: 2x + y = 7.
To isolate y, you can subtract 2x from both sides of the equation:
2x + y - 2x = 7 - 2x.
The 2x on the left side cancels out, leaving you with:
y = 7 - 2x.

We can rewrite the expression using power properties.
We have then:
42n ^ (4 + 5) - 30n ^ (1 + 5) + 30n ^ 5
Rewriting:
42n ^ 9 - 30n ^ 6 + 30n ^ 5
