Answer:138

Step-by-step explanation:

First plug in the c and d values into the expression:

6(5)^2-5(4)+8

Remember PEMDAS, so you do 5^2 first getting you 25.

6(25)-5(4)+8

Continue with PEMDAS and multiply -5 and 4, and that gets you -20.

150-20+8

Now you simplify the expression to get: 138.

The population of bacteria in a certain culture can be modeled by the function P(t)=10000(1.03)^t. Is the population of bacteria
ch4aika [34]

Answer:

The population of bacteria is increasing.

Step-by-step explanation:

The function modelling the population of bacteria in the given culture is an exponential function; We have a base 1.03 and an exponent t. An exponential function is said to be increasing if the base is strictly greater than 1, this implies that the population of the bacteria is increasing as t increases from 0 to infinity.

The following graph represents the distance a commercial airplane travels over time, at cruising speed and an altitude of 35,000
ANEK [815]

Answer:

see the explanation

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in hours

y ----> the distance in miles

<em>Find the value of k</em>

For the point (4,2268)

k=\frac{2,268}{4}=567\ mph

The slope represent the speed of the airplane

so

The linear equation is

y=567x

Part 1 :

The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.

Part 2 :

The  point  (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours

Tyger uses brick which are 7cm tall to build a tower.His final tower is 26 bricks high.How many cm tall is it?
iris [78.8K]
If the 26 bricks are each 7 cm, seems like multiplication or repeated addition would solve the problem. Multiplication would be faster. 26 x 7 = 182
182 cm tall.

.<br> How do we write simple expressions using long &amp; synthetic division?<br><br> Explain
igomit [66]

Answer:

For not exact divisions: Writing the results as Quotient + Remainder over the Divisor.

For exact division: just the quotient.

Step-by-step explanation:

Hi there,

In both algorithms, for long and synthetic divisions we must write the result as an expression following that order:

Dividend: Divisor=Qx+\frac{Rx}{Dx}

When the Division leaves no Remainder, i.e. an exact, the Remainder is equal to zero, so

Dividend: Divisor=Qx

Check below for the algorithms for each division and the way of writing their expressions (results).
