Answer:
1999
Step-by-step explanation:
y=-15x^2+64x+360
y=-15(1)^2+64(1)+360
y=409
(y is in millions)
I hope this helps!
Corresponding parts of similar triangles are proportional (CPSTP) is the property used here. Since the triangles are isosceles, then each non-base side is the same. The larger/left triangle has both sides of 215 meters and the smaller/right triangle has both sides of 43.
Let's make a proportion. On the tops are the sides, on the bottoms are the bases. On the left is the larger triangle, on the right is the smaller triangle. Keeping the pieces straight is what makes the proportion work.
To solve for x we can cross multiply.
215(x) = (230)(43)
215x = 9890
x = 46 after dividing both sides by 215
Thus the proportion is and the base is 46 meters.
25 meters per second x 60 seconds = 1500 meters per minute
1500 meters per minute x 60 minutes per hour = 90,000 meters per hour
1 mile = 1609.34 meters
90000/1609.34 = 55.92 miles per hour
round answer to either 55.9 or 56 mph depending on what you need.
Answer:
y=3/5x+3
Step-by-step explanation:
The y-intercept which is the (+3) is taken from where the line crosses the y-axis.
The slop is found from rise over run, in this case, -5 to 0 is positive 5 this would go in the denominator, because we go from solid ground 0 to 3 without crossing another solid point, the numerator is 3.
Answer:
/5.2 + 81.9 = 47.2
Step-by-step explanation:
Subtract 81.9 from both sides of the equation
Simplify
Subtract the numbers
Multiply all terms by the same value to eliminate denominators
Cancel multiplied terms that are in the denominator
Multiply the numbers
Solution: k = -180.44
