Answer:
x = 7 cm.
Step-by-step explanation:
The 2 triangles are similar so corresponding sides are in the same ratio.
Therefore:-
x / 42 = 6/36
x / 42 = 1/6
6x = 42
x = 7 (answer).
Can yu post the problem? my computer won't open the document
We can't answer the question without a picture of the figure.
The point-slope form:
We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:
Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:
A ball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms
Balls height
To find all values of t for which the ball's height is 3 meters
We plug in 3 for h and solve for t
Solve for t
Solve using quadratic formula
After simplifying this,
= 0.11898
= 1.68102
the values of t for which the ball's height is 3 meters= 0.12 sec , 1.68 sec
