Answer:

It is an Acute triangle

Step-by-step explanation:

A right triangle is 90 degrees

In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

a obtuse triangle is any angle from 91 to 179 degrees

an acute triangle is any angle from 1 to 89 degrees

a scalene triangle is a triangle when no sides are equal

and isosceles triangle has only two sides equal

plz thank me!

Answer:

Step-by-step explanation:

A is linear, you can figure out that y=x+5

B is linear, y=22(x+1)

C is linear, y=8x+5

D is exponential, y=3ˣ⁺¹

Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.

Factor the polynomial function over the complex numbers.

Bumek [7]

Answer:

$[x - 1][x + 1][{x}^{2} + 4]$

Step-by-step explanation:

Knowing that you have to find two numbers that when they differ to 3, they also multiply to −4, and those numbers are −1 and 4. So, after clearing that up, you will have this [since our degree of this polynomial function is 4]:

$[{x}^{2} - 1][{x}^{2} + 4]$

Then, since ${x}^{2} - 1$ is factorable, you will get this:

$[x - 1][x + 1]$

Finally, attach $[{x}^{2} + 4]$ to the partially factored polynomial to get this:

$[x - 1][x + 1][{x}^{2} + 4]$

I am joyous to assist you anytime.

Answer:

Area: 15.53 square inches

Perimeter: 15.71 inches

Step-by-step explanation:

Area:

So the area of the rectangle is pretty easy to find and is just the width * height. In this case it's 4 * 3 which is 12. Now the area of a circle is $\pi r^2$ . But since this is a semi circle it's half of that which is $\frac{\pi r^2}{2}$ . The diameter of the semicircle is 3 as it sits on top of the rectangle. The radius is half of the diameter so the radius is 1.5. Now plug that into the equation and you get $\frac{(3.14) (1.5)^2}{2} = 3.5325$ . Now add that to 12 and you get 15.5325. Round that number to the nearest hundredth and you get 15.53. So that's the area.

Perimeter:

Pi is the ratio of any circle's circumference to the diameter. Or in other words the circumference is equal to the diameter * 3.14. The diameter is 3 which you multiply by 3.14 to get the circumference of a circle. This will get you 9.42 but since it's a semicircle, the circumference is half of this value which is 4.71. The perimeter of the rectangle is just 2 times the width + 2 times the height. This is not completely the case in this shape since one of the sides of the rectangle is not a side of the two shapes joined together. Which is the side that is parallel to the side of length 3 inches. So the perimeter is going to be 2(4) + 3. This gives you 11 which you add to the 4.71 and get 15.71
