A.It is less than -7 5/8
because multiplying by a number less than 1
gives a smaller number.
B.It is greater than -4
because 0.36×(7 5/8)
0.36*(7 5/8) is less than 1/2 * 8
C.It equals -7 5/8
because 36/36
equals 1
, and 1
times any number equals that number.
D.It equals 0
because 0.36
rounded to the nearest whole number is 0
, and 0
times any number is 0.
THESE ARE ALL THE ANSWER CHOICES!!!
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.
If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.
So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
Answer:
∠F = 42° to the nearest degree
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle.
Kindly note that since one of the angles we are dealing with in the triangle is 90°, this means that the triangle is a right-angled triangle
Please check attachment for the diagrammatic representation of the triangle
From the diagram, we can identify that the EF is the hypotenuse and the length FG is the adjacent. Thus , the appropriate trigonometric identity to use is the cosine
mathematically;
Cosine of an angle = length of adjacent/length of hypotenuse

F = 42.07
∠F = 42° to the nearest degree
3 49/90
Step-by-step explanation:
7 11/78-4 1/15
(7-4)+(11/18-1/15)
3+49/90
3 49/90
3 19/90 or
3.5444444444
Namely, how much is 1/4 of 1/2? well is just their product
