To solve this question you first need to write out the equation that the question describes. The. You can solve for the height of the kiwi. (See image above)
Answer:
a = 5
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a =
= 5
K×4-7=k/2/3
4k-7=k×3/2
4k-7=1.5k
4k-7-4k=1.5k-4k
-7=-2.5k
-7/-2.5=-2.5k/-2.5
2.8=k
I worked the problem by hand. First I used the equation y=mx+b to find the rule for the function. To find m which is the same as the slope you use the change in y divided by the change in x. Or the change in output divided by the change in input. The two points or coordinates used were (-2,-4) and (1,-1). Once you have the slope you use y=mx+b and substitude y by any value of y (-4 or -1) and m is the slope calculated and x would be the corresponding x to the y value used (if -4 was chosen for y then -2 would be used for x). This will be used to calculate b.
