Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
Answer:
Center: (0, 0)
Radius: 4
Step-by-step explanation:
Circle Standard Equation: (x - h)² + (y - k)² = r²
(h, k) is center
r is radius
We see that our <em>h</em> and our <em>k</em> are both 0.
∴ Our center is (0, 0), origin.
We see that our r² = 16
√r² = √16
∴ Our radius is equal to 4

C
Answer:
0
Step-by-step explanation:
Use two-point form to find the slope.
m=y2-y1/x2-x1
m=0-0/10-5
m=0/5
If you start from the "standard" sine function, i.e.

You can change its graph in four ways:
Amplitude: you can multiply the whole function by a constant to stretch/squeeze it vertically. The transformation looks like

Phase: you can add a constant to the argument translate it horizontally. The transformation looks like

Period: you can multiply the argument by a constant to stretch/squeeze it horizontally. The transformation looks like

Shift: you can add a constant to the whole function to translate it vertically. The transformation looks like

In your case, we're changing the period of the function. If
the function is squeezed, so you're squeezing the graph horizontally by a factor of 7/4
