Answer:
3 units ×16 units
Step-by-step explanation:
Please see the attached picture for full solution.
Quadratic functions can be written in three forms. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring. ... The parameter is the y-intercept, while the parameter is the slope of the tangent at 0.
Answer:
never true
Step-by-step explanation:
on the left, you subtract 13 from x
on the right, you add 1 to x
because each side adjusts x differently, there will never be a solution.
Answer:
66.2
Step-by-step explanation:
We know that the middle 68% of the distribution is between -1 and +1 standard deviations from the mean. -1 standard deviation is a score of ...
69.9 - 3.7 = 66.2

<em>Comment on the question</em>
The way the question is worded, "A" can be any value less than 68.1, down to -∞. The question does does not require the A-B range to be symmetrical.
"Enlargement" here implies that the two pentagons are similar. Because of similarity, the following equation of ratios must be true: 7/15 = x/7. Then 15x=49, and x = 49/15 = 3.27 cm, approximately.
Rounded to the nearest tenth, that comes to 3.3 cm.
