Chandler is walking 1/16 km every 10 minutes. How many kilometers will he walk in 1 hour?!

SashulF [63]

Answer:

$\frac{3}{8} or\ 0.375\ km$

Step-by-step explanation:

Given: Chandler walk 1/16 km every 10 minutes.

First, lets find how many 10 minutes in one hours or convert minutes in hours.

∴ Time= $\frac{60}{10} \ h$

Now, finding kilometres travelled in 1 hour.

Distance travelled= $\frac{1}{16} \times \frac{60}{10} = \frac{1}{16} \times 6$

Distance travelled = $\frac{3}{8}$

Converting $\frac{3}{8} \ km$ into decimal will have 0.375 km.

∴ $\frac{3}{8} or\ 0.375\ km$ will chandler walk in 1 hour.

Given the equation 2 Square root of x minus 5 = 2, solve for x and identify if it is an extraneous solution.

Luba_88 [7]

Given: 2√(x - 5) = 2

Taking the square of both sides:

[2√(x - 5) = 2]^2

4(x - 5) = 4
x - 5 = 1
x = 6

Among the choices, the correct answer is A. x = 6, solution is not extraneous .

What is the equation of a line in general form that does not have a y-intercept and goes through the point (3,6) ?

Dennis_Churaev [7]

Answer:

$x = 3$

Step-by-step explanation:

Step 1: Determine the equation

So we know that our equation does not have a y-intercept which means that it doesn't intersect ANYWHERE on the y-axis. Therefore, this means that our equation will be a straight vertical line that doesn't move side to side and just goes straight up and down. We also know that our point is (3, 6) which means that our x-value will be 3 and this is where the equation will be located.

There are several ways to display our answer where x = 3 is the most common way which basically means give me all of the y-values for the same x value of 3. Another way of saying it is x - 3 = 0 which either way when adding 3 to both sides gives you x = 3 which is what I usually go with.

Answer: $x = 3$

Explanation:
Given:
x

14
x
2
+
60
x
+
72
=
0

By the rational roots theorem, any rational zeros of the given cubic are expressible in the form
p
q
for integers
p
,
q
with
p
a divisor of the constant term
72
and
q
a divisor of the coefficient
1
of the leading term.
That means that the only possible rational zeros are:
±
1
,
±
2
,
±
3
,
±
4
,
±
6
,
±
8
,
±
9
,
±
12
,
±
18
,
±
24
,
±
36
,
±
72
In addition, note that all of the coefficients are positive and the constant term is non-zero. As a result, any real zero (rational or otherwise) of this cubic must be negative.
So that leaves rational possibilities:
−
1
,
−
2
,
−
3
,
−
4
,
−
6
,
−
8
,
−
9
,
−
12
,
−
18
,
−
24
,
−
36
,
−
72
We find:
(
−

)
3

(

)
2

60
(
−
2
)
+
72
=
−

+
56
−
120
+
72
=

So
x
=
−
2
is a zero and
(
x

2
)
a factor:
x
3
+
14
x
2
+
60
+
72
=
(
x
+
2
)
(
x
2
+
12
x
+
36
)
Without trying any more of our "possible" zeros, we can recognise the remaining quadratic factor as a perfect square trinomial:
x
2
+
12
x
+
36
=
x
2
+
2
(
x
)
(
6
)
+
6
2
=
(
x
+
6
)
2
So the factored form of the given cubic equation can be written:
(
x
+
2
)
(
x
+
6
)
2
=
0
