Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
=6.3feet
Answer:Write in slope-intercept form, y=mx+b
.
y=4x+43

Answer:
b) three terms
c) -1
d) 7
e) 4
Step-by-step explanation:
put the expression in decreasing exponent order with the constant at the end
-x⁴ - 2x + 7
With this format it is easy to find the leading coefficient which is the coefficient of the term with the highest exponent; in this case you only see a negative sign but every variable, if no other coefficient is present, has an invisible '1'
A) 86 x 4= Width (86x4)+8= Length
b) Width = 384, 384+8= 392. Length= 392
Answer:
No
Step-by-step explanation:
They are not equivalent because in |x-5|, the answer is always positive.
In |x|-5, the answer can be negative if x is less than 5.
