Expanded FormExpanded form refers to a base and an exponent written as repeated multiplication. ExponentExponents are used to describe the number of times that a term is multiplied by itself. ExpressionAn expression is a mathematical phrase containing variables, operations and/or numbers.
Answer:
∠ PQR = 70°
Step-by-step explanation:
The tangent- tangent angle PQR is half the difference of the intercepted arcs.
minor arc PR = 360° - 250° = 110°
Then
∠ PQR =
(250 - 110)° =
× 140° = 70°
If you multiply 48cm times 15cm,you get 720cm.Which would leave you with 60 left because 780 minus 720 equals 60.The height of the other base is 60cm.
Answer:

Step-by-step explanation:
Slope intercept form is
where <em>m </em>is the slope and <em>b </em>is the y-intercept.
Slope is
or
in this case = 
Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

since m = 2 and b = -4, we can conclude that the equation would be
