Answer:

option (b) is correct.

Step-by-step explanation:

Given : the equation $(x+8)^2+(y-1)^2=9$

We have to plot the graph for the given equation $(x+8)^2+(y-1)^2=9$ and choose the correct graph

Since the general equation of circle is given as, $(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center of the equation and r is the radius.

Thus, for the given equation $(x+8)^2+(y-1)^2=9$

on comparing we have h = -8 , k = 1 , r = 3

Thus, the graph will be a circle with center at (-8, 1) and radius 3 .

Thus, the graph in option (b) is correct.

In the diagram abc=adb=90, ad=p and dc=q. Use similar triangles to show that x2=pz plzz anyoneee

kramer

Answer:

By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that $x^{2} =pz$

Step-by-step explanation:

Given that ∠ABC=∠ADC, AD=p and DC=q.

Let us take compare Δ ABC and Δ ADB in the attached file , ∠A is common in both triangles

and given ∠ABC=∠ADB=90°

Hence using AA postulate, ΔABC ≈ ΔADB.

Now we will equate respective side ratios in both triangles.

$\frac{AB}{AC}= \frac{AD}{AB}=\frac{BD}{BC}$

Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.

$\frac{x}{z}= \frac{p}{x}$

Cross multiply

$x^{2}=pz$

Hence proved.

Plastic Knives are sold in packs of 18 for 45p. Plastic Forks are sold in packs of 15 for 41p. Jace wants to buy the same number

Flauer [41]

Answer:

430p

Step-by-step explanation:

For this, we'll find the least common multiple for 15 and 18.

=> The least common multiple for 15 and 18 is 90

Plastic Knives:

Jace will buy 90 knives.

=> Packets = 90/18 = 5 Packets

Money for 5 Packets = 5 * 45

=> 225p

Plastic Forks:

Jace will buy 90 forks also.

=> Packets = 90/15 = 6 Packets

Money fro 6 packets = 6 * 41

=> 205p

Least Amount of Money Jace will spend = 225p+205p

=> 430p

Quincy says that 3 is a good estimate for 3.4 X 0.09, is he correct? Why?

lord [1]

Quincy says that 3 is a good estimate for 3.4 X 0.09, is she correct? Why?
When we say estimates meaning it is not the exact answer but close to what is the exact.
Now, if Quincy estimated 3 as the product of 3.4 * .09, then let’s check if she has the correct estimates.
=> 3.4 estimates is 3
=> 0.09 estimates is 0.1
Now the answer is 0.3 and not 3.
Thus, Quincy’s estimate is wrong.
