o-na [289]3 years ago

Answer:

x = 70.71

Step-by-step explanation:

log 2x² + 2 = 6.

log 2x² + log 100= log 10⁶.

2x² × 100 = 10⁶

2x² = 10⁶/100

2x² = 10⁴

x² = 10⁴/2

x² = 5000

x = √5000

x is approximately 70.71

x = 70.71

The time required to do a job varies inversely as the number of people working. It takes 5hr for 7 bricklayers to build a park w
ExtremeBDS [4]

<u>Answer</u>

3.5 hours.


<u>Explanation</u>

The first step is to calculate the constant of proportionality.

t ∝ 1/n

t = k/n   Where t = time, K= constant and n = number of people

t = k/n

k =tn

   = 5×7 = 35

The equation becomes;

t = 35/n

for n = 10,

t = 35/10

  t = 3.5 hours.

Graph y=-2x. give the domain and range. is the function dicrete or continou?
r-ruslan [8.4K]

Answer:

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Step-by-step explanation:

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

I am thinking of two numbers. The sum of the two is 10 and the difference is 2
mixer [17]

Answer:

4 and 6

Step-by-step explanation:

First, let's find all the pairs that add up to 10.

  • 1 + 9, 2 + 8, 3 + 7, 4 + 6, and 5 + 5

Next, we find the difference between the addends for each pair.

  • 9 - 1 = 8
  • 8 - 2 = 6
  • 7 - 3 = 4
  • 6 - 4 = 2
  • 5 - 5 = 0

As you can, see the numbers that add to 10 and have a different of 2 is 4 and 6.
