1 answer:

6 0

An=a1+d(n-1)
a1=firt term
d=commondifference

-1-4=-5

common difference=-4
first term is -1

an=-1-4(n-1)
40th term
a40=-1-4(40-1)
a40=-1-4(39)
a40=-1-156
a40=-157

40th term is -157

What is the approximate value of q in the equation below?

gayaneshka [121]

<u>Given</u>:

The given equation is $q+\log _{2}(6)=2 q+2$

We need to determine the approximate value of q.

<u>Value of q:</u>

To determine the value of q, let us solve the equation for q.

Hence, Subtracting $\log _{2}(6)$ on both sides of the equation, we get;

$q=2 q+2-\log _{2}(6)$

Subtracting both sides of the equation by 2q, we have;

$-q=2-\log _{2}(6)$

Dividing both sides of the equation by -1, we have;

$q=\log _{2}(6)-2$

Now, substituting the value of $log_2(6)=2.585$ , we have;

$q=2.585-2$

Subtracting the values, we get;

$q=0.585$

Thus, the approximate value of q is 0.585

Hence, Option C is the correct answer.

Compute the selling price of a sports drink that has a cost of $1.25 per item. The store needs to generate a profit of $0.50 per

luda_lava [24]

Answer:

The selling price would be $\$1.75$ .

Step-by-step explanation:

We have been given that a sports drink has a cost of $1.25.

We need to figure out the selling price of the sports drink so that the store is able to generate a profit of $0.50 per drink.

We know that profit is found by subtracting the cost of an item from selling price of the item. Therefore, selling price of the item can be found by adding the profit to the cost.

Therefore, the required selling price of the sports drink would be:

$\$1.25+\$0.50=\$1.75$
