Answer:
Number of Starbursts= 66
Step-by-step explanation:
Method:
The first step in working out the number of Starbursts in the bowl is to add the the ratios of 3 and 4, this gives you 7.
The next step is to divide the total number of sweets which is 154 by the value of 7, this gives you 22. This is because we are trying to find out the value of one in the ratio.
The final step would be to work out the number of Starbursts in the bowl. This can be done by multiplying 22 by the ratio for Starbursts which is 3, this gives you 66. This means that out of 154 sweets 66 of them were starbursts.
Set by step:
1) Add 3 and 4.
2) Divide 154 by 7.
3) Multiply 22 by 3.
The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis ⇒ Last answer
Step-by-step explanation:
Let us revise some transformation
A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis.
A horizontal stretching is the stretching of the graph away from the y-axis
- If k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally shrunk (or compressed) by dividing each of its x-coordinates by k.
- If 0 < k < 1 (a fraction), the graph of y = f(k•x) is the graph of f(x) horizontally stretched by dividing each of its x-coordinates by k
- If k should be negative, the horizontal stretch or shrink is followed by a reflection across the y-axis
∵ y = √x is a parent function
∵ Its graph transformed to produce the graph of y = √(-2x)
- That means x is multiplied by a factor k, then it is compressed
or stretched horizontally
∵ k = -2
- The factor is -2, where 2 is greater than 1, then it is compressed
horizontally as the first rule above and the negative means
reflected across the y-axis as the third rule above
∴ The graph of the parent function is compressed horizontally and
reflected across the y-axis
The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis
