The distance between a chord and the center of a
circle is 4 cm. What is the radius of the circle if
the chord measures 16 cm?

Answer:

$6.69448

Step-by-step explanation:

I=?

P=$266.50

R=2.5*1/100=2.5/100

T=12

P*R*T

$266.50*2.5/100*12=$6.69448

Answer:

A 72cm

Step-by-step explanation:

Area of a triangle = 1/2 base x height

= 1/2 × 8× 9 = 36cm2

area of triangle = area of square

36cm2 = 36cm2

area of square = length x breath

= x x x = 36cm3

square has all sides(4) equal

therefore: 36/ 2 = 18cm (one side)

(18 x 18= 36cm3, so area is correct)

hence perimeter = 18+ 18+18+18 = 72cm

Answer:

[tex]y-8+2\leq -2+2[/tex]

Step-by-step explanation:

Since you're adding either 8 or 2 to both sides, the inequality sign doesn't change.

So we can eliminate the first and second choice.

Now it's down to the bottom two.

The third choice is adding 2 to the left hand side and then adding 8 to the right hand side. You can't add two different numbers to different sides.

Therefore, the last one must be the correct answer.

The last one is adding two to both sides and have the same inequality sign.

Answer:25.50

Step-by-step explanation:

Because .50 is in the hundreths, and it rounds up to that because it is above 5.

Answer:

1) x=11

2)x=9

3)pr=21

4)fe=68

Answer:

x² + y² = 6

Step-by-step explanation:

The standard form of the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Here r = [tex]\sqrt{6}[/tex] , then

x² + y² = ([tex]\sqrt{6}[/tex] )² , that is

x² + y² = 6

[tex]2688[/tex]

1) Simplify 2 × 8 to 16.

[tex]16 \times 12 \times 14[/tex]

2) Simplify 12 × 16 to 192.

[tex]192 \times 14[/tex]

3) Simplify.

[tex]2688[/tex]

So, therefor, the answer is, 2688.

Answer

1 7/12

Step-by-step explanation:

Answer:

At t=2s the car  reach its minimum speed

Minimum speed=8m/s

Step-by-step explanation:

We are given that velocity of car

[tex]v(t)=t^2-4t+12[/tex]

0<t<4

Differentiate w.r.t t

[tex]v'(t)=2t-4[/tex]

[tex]v'(t)=0[/tex]

[tex]2t-4=0[/tex]

[tex]2t=4[/tex]

[tex]t=2[/tex]

[tex]v''(t)=2>0[/tex]

The velocity is minimum at t=2 s

Substitute t=2

[tex]v(2)=2^2-4(2)+12[/tex]

[tex]v(2)=8m/s[/tex]

Hence, the speed of car is minimum at t=2 se and minimum speed of car=8m/s

Step-by-step explanation:

Answer:

1) x<2.5 2) x<2.5 (both are smaller numbers than 2.5)

Step-by-step explanation:

I'm sure there is a easier way to figure this question out but how I did is by simply imputing numbers smaller or bigger into where the x is. For example, I imputed 3 into -4x+5>-5. So, -4(3)+5>5, = -7>5, this is false, so x must be smaller than 2.5 in order for this to be true.

Answer:

y = -13x+26

Step-by-step explanation:

13x+y=26

y= -13x+26

Answer: B) No; the remainder is 234, so (x+3) is not a factor.

===============================================================

Explanation:

We'll use the remainder theorem. That theorem says if we divide p(x) over (x-k), then the remainder is p(k). A special case of this theorem says that if we get 0 as the remainder, then (x-k) is a factor of p(x).

We're dividing f(x) over (x+3) which means that k = -3. Think of x+3 as x-(-3) so you can match it up with the form x-k.

To find the remainder of f(x)/(x+3), we need to compute f(-3).

Plug x = -3 into the f(x) function to get...

f(x) = 4x^3 + 11x^2 - 75x + 18

f(-3) = 4(-3)^3 + 11(-3)^2 - 75(-3) + 18

f(-3) = 234

The remainder is 234, which is isn't zero, so (x+3) is not a factor of f(x).

Answer:

No; the remainder is 0 so (x + 3) is not a factor

Answer:

Step-by-step explanation:

Y varies directly with x:

y=kx

for some non-zero constant k

substitute y=150 and x=3:

150=3k

k=50

When y=600:

600=(50)x

x=12

Answer:

the perimeter is 16

Step-by-step explanation:

The computation of the shape on this centimeter grid is shown below:

As we can see in the attached figure that the some portion is highlighted

So if we count that

like

So after counting it comes 16

Therefore the perimeter is 16
