the diameter is a circle is 16cm. Find it’s circumference in terms of π.

C= ________cm

Answer:

4x^2 B

-4x^2 A

1/4x^2 D

-1/4x^2 C

Step-by-step explanation:

1. Look at the concavity

    up or down = negative or positive.

2. number before the x value

if N < 1, it will be wider.     if N > 1, it will be thinner.

3. the two most right graphs would be -1/4x^2 and 1/4x^2

the one that is concave down is the - and the concave up is +

Answer:

E’(-5,1)

Step-by-step explanation:

Answer:

141 km

Step-by-step explanation:

Given data

Mean distance= 153km

Let Tina dirve=x km

Ben= x+ 24

Number of participants= 2

Hence,

Mean= total distance/number of participants

153= x+24+x/2

cross multiply

153*2= x+24+x

306 =2x+24

306-24= 2x

282=2x

Divide both sides by 2

x= 282/2

x= 141km

Hence Tina drove 141 km

Answer:

Step-by-step explanation:

The total surface area of a cone with radius r and slant height s is ...

  A = πr² +πrs = πr(r +s)

For the given dimensions and π≈3, the area is approximately ...

  3(2 cm)(2 cm +8 cm) = 60 cm²

For π≈3.14, the area is approximately ...

  (20cm²)(3.14) = 62.8 cm²

A. 16 to 20 is equivalent to ratio 32:40

Answer:

rational: √(42)/√(168), √(64)/32, (5√(3)-√(3))/(2√(3))

irrational: 2√(5)-3√(6), √(5)(4√(5-3√5))), √(7)π-√(14)π

Step-by-step explanation:

You can use calculater to find them.

If it can form fraction, then it is rational.

Answer:

5/8 (= 0.625)

Step-by-step explanation:

tan A = sin A / cos A

we have here a triangle that is much bigger than to fit into our snuggly around a norm circle (radius = 1).

so, we could either see it embedded in a circle with a radius of the square root of 89, or surrounding a circle with the radius of 8.

in the first case

[tex]5 = \sin(a) \times \sqrt{89} [/tex]

[tex]8 = \cos(b) \times \sqrt{89} [/tex]

in the second case 5 is already tan A but stretched by the radius 8.

so,

[tex]5 = \tan(a) \times 8[/tex]

so, in both cases the answer is 5/8.

Answer:

48

Step-by-step explanation:

16+16+16 or 16 x 3

hope it helps <3

Answer:

48 yards

Step-by-step explanation:

To calculate the perimeter you have to add the outline of the triangle together.

16 + 16 + 16 = 48

You can also do 16 × 3 = 48

So, your answer is 48 yards.

Have a great day! :)

Answer:

B

Step-by-step explanation:

The SA of a cone is A=pi*r^2+pi*r*s

So instead of pi*5^2, it should be pi*3*5 (5 is the length of the slant).

Answer:

To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.

Step-by-step explanation:

Third option, counting from the top.

Remember that we say that a limit exists, like:

[tex]\lim_{x \to 0} f(x) = a[/tex]

if and only if:

[tex]\lim_{x \to 0_-} f(x) = a[/tex]

and

[tex]\lim_{x \to 0_+} f(x) = a[/tex]

Where the above two limits say that when we approach zero from the negative side (the first one) and from the positive side (the second one), we must get the same value.

Also, remember that the limit is an approximation through near points

Then, regardless the fact that f(0) = -2, we can see that as x approaches 0 from both sides, the value of the function approaches 4.

Thus, we can conclude that the limit of f(x) when x tends to zero is equal to 4.

The correct option is the third one.
