-log(5.4x10^-9) = 8.27 = 8.3
since 8.3 is greater than 7 it is basic
so the last answer is correct
Answer:
22
Step-by-step explanation:
First arrange the given data in ascending order
17 17 17 18 20 21 21 22 22 22 22 22 22 22.5
The median is the middlemost value, so the median is 22
Answer:
The numerical length of MO is 20 units
Step-by-step explanation:
Let us solve the question
∵ Point N is on line segment MO
→ That means point N divides segment MO into two parts MN and NO
∴ MO = MN + NO
∵ MO = 2x + 5
∵ MN = 2x + 3
∵ NO = 2x - 3
→ Substitute them in the equation above
∴ 3x + 5 = (2x + 3) + (2x - 3)
→ Add the like terms in the right side
∵ 3x + 5 = (2x + 2x) + (3 - 3)
∴ 3x + 5 = 4x + 0
∴ 3x + 5 = 4x
→ Subtract 3x from both sides
∵ 3x - 3x + 5 = 4x - 3x
∴ 5 = x
∴ The value of x is 5
→ To find MO substitute x by 5 in its expression
∵ MO = 3x + 5
∴ MO = 3(5) + 5
∴ MO = 15 + 5
∴ MO = 20 units
The numerical length of MO is 20 units
Answer:
A: 30 m
B: 14 boxes
C: $596.40
D: $477.12
Step-by-step explanation:
A: 6*4.2 = 25.2. 3.2*1.5 = 4.8. 25.2 + 4.8 = 30.
B: 30/2.15 = 13.95, which rounds to 14.
C: 14*42.60 = $596.40
D: 20% off 100% = 80%, which is equal to 0.8. 596.40*.8 = $477.12.
Hope it helps you!! :)
Vertices (3,0),(-3,0) co-vertices (0,-5),(0,5)
transverse axis (line passing vertices) is on(or parallel to) x-axis then formula is
(x-h)^2/a^2 - (y-k)^2/b^2 = 1
..notice.. x^2 is on positive / y^2 is on negative
center (h,k) is midway between vertices = (0,0)
we have h = k = 0 and now formula is
x^2/a^2 - y^2/b^2 = 1
a is the distance from a vertex to center = 3
b is the distance from a co-vertex to center = 5
the formula is
x^2/3^2 - y^2/5^2 = 1 ... answer is the 1st
