Parallelogram:
just multiply 16 by 30.
The area is 480.
Semicircles:
Since there are 2 semicircles, they can be merged to one circle.
The area of a circle is πr²
The diameter is 28, so the radius is 14.
Substitute and solve.
π14²
π196 ≈ 615.8
Now add 615.8 with 480
Your answer is 1,095.8 units squared.

Which trinomial is a perfect square trinomial? a2 – 18a + 36 a2 – 16a + 64 a2 – 8a + 64 a2 – 6a + 36
Komok [63]

Answer:

a^2-16a+64

Step-by-step explanation:

we have the options

a^2-18a+36\\a^2-16a+64\\a^2-8a+64\\a^2-6a+36

the one that is a perfect equare tinomial is:

a^2-16a+64

because we can rewrite this as follows:

(a-8)^2  this is because we know that

x^2-2xy+y^2=(x-y)^2

thus

a^2-16a+64=(x-8)^2

and the other options cannot be represented as a perfect square trinomial, so the correct answer is:

a^2-16a+64

Manny observed a Northern Gannet, a deep diving seabird, hovering at a height of 10 meters above the ocean surface. The bird the
mr Goodwill [35]

Answer:

9.2 seconds.

Step-by-step explanation:

We have been given an equation that represents dive of a bird as y=x^2-10.3x+10, where x represents the time the dive lasted in seconds and y represents the height of the bird in meters.

We can see that our given equation is a parabola. The leading coefficient is positive, so our parabola will be an upward opening parabola.

Upon graphing our given equation, we will get our required graph as shown in the attachment.

As x represents the time the dive lasted in seconds and y represents the height of the bird in meters, so the bird will be at the surface when the graph will cross x-axis.

We can see that graph crosses x-axis at x=1.085\text{ and }x=9.215.

Upon rounding to nearest tenth, we will get:

x\approx 1.1\text{ and }x=9.2.

At x\approx 1.1 the bird dives in water and goes down the water surface and at x=9.2 the bird comes to the surface, therefore, the bird will be at surface after 9.2 seconds.
