-1u + 5. The first thing to do is add like terms (-2u and u) (1 and 4). -2u + u is -1u or -u. 1 + 4 is 5. I hope this helps!!

What is the area of this figure? Round to the tenth if necessary.

Julli [10]

Answer:

<h3>b) 850.1 centimeters.</h3>

Step-by-step explanation:

To find the area of this figure, we must first find the areas of the shapes that compose this figure.

This figure is made up of a rectangle and a semicircle.

Remember: To find the area of a semicircle, multiply the radius by itself twice, then multiply the product pi, lastly divide the product by 2.

$a=\pi r^2/2$

To find the area of a rectangle, multiply the length by the width. The product is the area of the rectangle.

$a=lw$

Now, let's solve.

The diameter of the semicircle is 32 centimeters.

To find the radius of a semicircle, divide the diameter by 2.

$32/2=16$

The radius of the semicircle is 16 centimeters.

Now that we have the radius, we can find the area of the semicircle.

$\pi 16^2/2=401.92$

The area of the semicircle is 401.92 centimeters.

Furthermore, we find the area of the rectangle.

$14*32=448.$

The area of the circle is 448 centimeters.

Next, we add the areas of both shapes to find the area of this figure.

$401.92+448$

$=849.92$

The final step is to round 849.92 to the nearest tenth.

Even though 849.92 to rounded to the nearest tenth is 849.9, there is no answer choice for this. The closest one to this answer is choice 'b.'

I, therefore, believe the area of this figure is 850.1 centimeters.

PLEASE HELP ASAP!! ILL GIVE BRAINLIEST IF CORRECT

Natalka [10]

Answer:

Function 1 has a greater Y intercept than that of function 2

Step-by-step explanation:

Y intercept can be found by replacing x by 0 or

x = 0 0f the given function.

in this case Function 1 has a Y intercept of 5 when x =0

on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.

you can now clearly see that

y = 5 > y = -1

---> 5>-1

so that's why we conclude that 1 has a greater Y intercept.

Sketch a graph of the function. Given the piecewise definition f(x) ={- 2x - 4 if x < - 2 f (x)= {x+3 if x>-2 Domain: Rang

kakasveta [241]

Explanation:

$f(x)=\begin{cases}-2x-4\text{ if x -2}\end{cases}$

The line of the first part of the function, without the restriction of x <=-2:

The line of the second part of the function, without the restriction is:

To graph the full function, we have to draw a line over the green dashed line until x = -2 and then continue drawing but now over the orange dashed line

Answer:

The graph of the function is:

• Domain:

$\begin{gathered} (-\infty,\infty) \\ \text{ or also} \\ -\infty• Range[tex]\begin{gathered} \lbrack0,\infty) \\ \text{ or also} \\ 0\le y$

bazaltina [42]

Answer:

-3.5 °F

Step-by-step explanation:

If the temperature change was the same each hour, we can find the change each hour by dividing -14 by 4.

-14/4= -3.5

= -3.5 °F
