What is 9 + 10? This is hard homework

Find the area of the trapezoid using the formula using the A=1/2h(b1+b2)

pentagon [3]

Answer:

9

Step-by-step explanation:

1/2 bh (b1+b2)
Count all the squares for the base (6 squares)
Half it bc 1/2bh, which is not 3(h)
Now count the amount of squares to the top of it from the bottom (3 as well)
Now the problem is 3(3) which is 9.
So, the answer is 9

Hope this helps! Comment on it if you need more explanation!:)

A Pringles chip can has a diameter of about 2.8 inches and a height of about 11.8 inches (close to real measurement) what volume

NARA [144]

Answer:

72.66 in³

Step-by-step explanation:

The volume of a cylinder of radius r and height h is given by V = πr²h.

Here we have V = πr²h = π([2.8]/2 in)²(11.8 in) = π(1.96 in²)(11.8 in) = 23.1 π in³, or approximately 72.66 in³

Find the equation of the line with slope m=1 that contains the point (1,2)

AnnyKZ [126]

Answer:

y = x + 1

Step-by-step explanation:

We can use the point-slope formula to write an equation for this problem. The point-slope formula states: (y - y1) = m (x - x1)

Where m is the slope and (x1 y1) is a point the line passes through.

Substituting the slope and the values from the point in the problem gives:

( y - 2 ) = 1 ( x - 1 )

We can also solve for y to put the equation in slope-intercept form. The slope-intercept form of a linear equation is: y = mx + b

y - 2 = 1x - 1

y = 1x - 1 + 2

y = 1x + 1 or y = x + 1  * are just the same.

Solve four tenths plus four ninths

DENIUS [597]

Answer: 38/45

Step-by-step explanation:

4/10 + 4/9

Lowest Common Multiple of 9 and 10 is 90. Rewrite fractions as 36/90 and 40/90. Add the numerators to get 76/90. Simplify that and you get 38/45, or 0.8444 (four repeating).

What is the end behavior in the function y=2x^3-x

sasho [114]

Answer:

Step-by-step explanation:

When a question asks for the "end behavior" of a function, they just want to know what happens if you trace the direction the function heads in for super low and super high values of x. In other words, they want to know what the graph is looking like as x heads for both positive and negative infinity. This might be sort of hard to visualize, so if you have a graphing utility, use it to double check yourself, but even without a graph, we can answer this question. For any function involving x^3, we know that the "parent graph" looks like the attached image. This is the "basic" look of any x^3 function; however, certain things can change the end behavior. You'll notice that in the attached graph, as x gets really really small, the function goes to negative infinity. As x gets very very big, the function goes to positive infinity.

Now, taking a look at your function, 2x^3 - x, things might change a little. Some things that change the end behavior of a graph include a negative coefficient for x^3, such as -x^3 or -5x^3. This would flip the graph over the y-axis, which would make the end behavior "swap", basically. Your function doesn't have a negative coefficient in front of x^3, so we're okay on that front, and it turns out your function has the same end behavior as the parent function, since no kind of reflection is occurring. I attached the graph of your function as well so you can see it, but what this means is that as x approaches infinity, or as x gets very big, your function also goes to infinity, and as x approaches negative infinity, or as x gets very small, your function goes to negative infinity.
