Answer:

2.34 x 10^-3

Step-by-step explanation:

To make 234 between 1 and 10, we need to shift the decimal place two to the left. But since we are making this number smaller, we have to adjust the 10 multiplier by mutliplying 100, which makes 10 ^-3

234 = 2.34 x 10^2

2.34 x 10^2 x 10^-5 = 2.34 x 10^-3

MrRissso [65]

The age of the van owned = 12 years

The age of the truck owned = 29 years

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?

Let us assume the number of years Laura has owned the van = S years

So, according to the question:

The number of years she has owned truck = S + 17 years

Now, Sum of the age of ( Truck + Van) = 41 years

⇒ (S + 17 years) + (S years) = 41 years

or, 2 S + 17 = 41

or, 2 S = 4 1 -1 7 = 24

or, S = 24/2 = 12 years

or, S = 12 years

Hence the age of the van owned = 12 years

The age of the truck owned = S + 17 = 12 + 17 = 29 years

A company sells widgets. The amount of profit, y, made by the

vfiekz [6]

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :

$y = -4x^2 + 183x- 1247$ ...(1)

We need to find out the maximum amount of profit the company can make.

For maximum profit put dy/dx = 0

So,

$\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87$

Put x = 22.87 in equation (1). So,

$y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06$

So, the maximum profit is 846.06 units.

g There are 3 signal transmitters T1,T2 and T3. Each one sends a signal to a receiver R and R sends three signals back to the th

ANEK [815]

Answer:

Recall that probability is given as; the number of required outcome over the number of total possible outcome.

The probability that a transmitter receives the signal being sent by itself is given as $\frac{1}{3}$ .

when there are n transmitters, the probability will be given as $\frac{1}{n}$

Step-by-step explanation:

Probability simply the likelihood of an event occurring or not occurring.

Probability therefore is given as; the number of required outcome over number of possible outcome.

In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.

while in the second part we have the number o possible outcome to be n.
