Between which two consecutive whole numbers does √ 78 lie?
a.
8 and 9
b.
6 and 7
c.
9 and 10
d.
7 and 8
A. 8 and 9
8^2 = 8 × 8 = 64
9^2 = 9 × 9 = 81
B. 6 and 7
6^2 = 6 × 6 = 36
7^2 = 7 × 7 = 49
C. 9 and 12
9^2 = 9 × 9 = 81
12^2 = 12 × 12 = 144
D. 7 and 8
7^2 = 7 × 7 = 49
8^2 = 8 × 8 = 64
The correct answer is A. 8 and 9
<h3>
Answer:</h3>
b= -14
Step-by-step explanation:
<em>f </em>(<em>x</em>)= -5<em>x +</em> 1
first replace the f with 5 and the x with -3 ,...............................which will give you the answer : -15 + 1= -14
Here's a hint on how to add negative# and positive numbers:
Same team ...Yay its a positive
ex:
-2+ -4=6
2+7=9
Opposite team ... Nay its a negative
ex:
-23+2=-21
-22+12=-10
-15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

An equilateral triangle has all three angles as 60 degrees, this also makes the triangle an acute triangle.
This makes both p and q true.
P V q is also true, the V means “or”, so if either p or q is true the statement is true
p ∧ q means and, since both p and q are true, this is also true.
The left and right arrows means “implies”, so this is true if and only
if the p is false or q is true (the sentence ((~p)vq) is true). Since Both p and q are true both the left and right arrows are true
The last one means equal and is true if both p and q are the same, which they are, so this is also true,.
All the given statements are true.,
To convert from radians to degrees multiply by 180 / π, So:-
3 π / 5 = 180 * 3 * π / 5π
= 540 / 5
= 108 degrees answer
