The function in vertex form is f(x) = (x-4)2-11
the y-intercept of the function is (0,5)
the function crosses the x-axis twice
Answer:
Enzo is not correct because he did not multiply the length and width by the same factor.
Step-by-step explanation:
Enzo is making a scale drawing of the rectangle below.
A rectangle has a length of 8 centimeters and width of 5 centimeters.
Suppose a new rectangle will have the length of 16 cm.
Since then the scale factor is 2.
If a scale factor is two, then the width of a new rectangle must be
But Enzo says that he can draw an enlarged rectangle that is 16 centimeters by 13 centimeters. Thus, Enzo is not correct because he did not multiply the length and width by the same factor.
Given:
Right triangle with one angle 45°
To find:
The value of q and r.
Solution:
Opposite to θ = 16
Adjacent to θ = r
Hypotenuse = q
Using trigonometric ratio formula:
The value of tan 45° = 1
Do cross multiplication, we get
r = 16
Using trigonometric ratio formula:
The value of sin 45° = .
Do cross multiplication, we get
The value of r is 16 and the value of q is .
