Is x = 0 a valid potential solution to the equation log(x + 2) + log(x + 5) = 1? (You don't need to solve this equation, just de

termine if x = 0 is a valid solution) Question 22 options: No, because log(0) is undefined. No, because the logarithm of a negative value is undefined. It can't be determined from the information given. Yes, since log(2) and log(5) both exist as valid values for the logarithm.

1st Step

40 (km per hour) × 60 (minutes in a hour) × 60 (sec per hour)

144000

Find double of the 144000

Ans = 288000

Step 2

Find the half of 144000

true or fales: a significant correlation indicates that changes in the values of one factie cause changes in the values of a sec
natka813 [3]

Answer:

A significant correlation means that there is a significant (in a statistical point of view) correlation between two things.

Then a significant correlation means that we have a (measurable) correlation between the variables in our experiment.

Now, the factors are the variables that experimenters control during an experiment in order to determine their effect on the response variable, then having a positive correlation between two factors, means that when we change one, the other is also affected by the change in the first one.

Then the statement is true.

Please help me with this math question
Dmitriy789 [7]

Answer:

6cm ; 22cm

Step-by-step explanation:

Given that:

Total Length, AD = 28cm

AB =x cm

BC = (x +5)cm

CD = 2x - 1 cm

4x + 4 = 28

4x = 28 - 4

4x = 24

x = 24 / 4

x = 6cm

The length of BD

BD = BC + CD

BD = (x + 5) + (2x - 1)

x = 6

BD = (6 + 5) + (2(6) - 1)

BD = 11 + (12 - 1)

BD = 11 + 11

BD = 22 cm

If PQRS is a rectangle, find the length of QT
MAVERICK [17]

Step-by-step explanation:

Since, opposite sides of a rectangle are equal and each angle is of 90°.

\therefore QP = RS = 14 cm

In \:\triangle QPS, \: \angle QPS = 90\degree

\therefore \: QS=  \sqrt{QP^2+ PS^2}   \\  \therefore \: QS=  \sqrt{(14)^2+ (20)^2 }  \\  \therefore \: QS=  \sqrt{196 + 400}  \\ \therefore \: QS=  \sqrt{596} \\ \therefore \: QS=  24.41 \: m

\because Diagonals of a rectangle bisects each other.

\therefore\: QT = \frac{1}{2} QS\\\therefore\: QT = \frac{1}{2} \times 24.41\\\therefore\: QT =12.205\\\huge\orange {\boxed {\therefore\: QT =12.21\:m}}
