Apply the standard equation of a circle with center at (h,k) and radius r:

(x-h)^2 + (y-k)^2 = r^2

Using the given data,

(x-2)^2 + (y+4)^2 = 3^2

Tim drives a average speed og 80km per hhour for 3 hours 45 minutes work out how many kilometers tim drives

andrew-mc [135]

The distance Tim drives is 300 kilometers

Average speed= 80 km

Time= 3 hours 45 minutes (15/4 hours)

Distance= Average speed/time

= 80 × 15/4

= 1200/4

= 300 kilometers

Hence the distance Tim drives is 300 kilometres

James has 3 blue candies and 3 green candies. 3 people come in and take 2 candies. What is the probability that they do not take

charle [14.2K]

Answer:

33.3333333333

Step-by-step explanation:

we see that there are 6 candies in total

we also see that there is a 50% chance that someone will take out 3 candies of the same color,

50/3 = 16.66666666666667

so the chance of getting 2 marbles of the same color is 16.66666666666667 + 16.66666666666667 which is 33.3333333333

I hope I could help

Given ΔADC and ΔAEB, What is AE?

chubhunter [2.5K]

Answer:

AE = 43.2 units

Step-by-step explanation:

As per the given question image, it can be seen that in the $\triangle ADC \text { and }\triangle AEB :$

1. $\angle B = \angle C = 90^\circ$

2. $\angle A$ is common to both the triangles.

3. Two angles are common, so the third angle $\angle E$ is also equal to $\angle D$ .

All the three angles in the $\triangle ADC \text { and }\triangle AEB$ are equal to each other, hence the triangles are similar.

As per the property of similar triangles, the ratio of their sides will be equal.

AB : AC = AE : AD

AC = 88 units

BC = 55 units

AB = AC - AB = 33 units

Let side AE = $x$ units

Side AD = AE + ED

So, AD = $x + 72$

Using the ratio:

$\dfrac{AB}{AC} = \dfrac{AE}{AD}\\\Rightarrow \dfrac{33}{55} = \dfrac{x}{x+72}\\\Rightarrow 55x = 33 \times 72\\\Rightarrow x = \dfrac{3\times 72}{5}\\\Rightarrow x = 43.2\ units$

So, AE = 43.2 units

Let f(x) = x 7 and g(x) = x − 4. find f(x) ⋅ g(x). x2 − 3x − 28 x2 − 3x − 11 x2 3x − 28 x2 3x − 11

vladimir1956 [14]

(x + 7)(x - 4) = x^2 - 4x + 7x - 28 = x^2 + 3x - 28
