The equation of a circle is x^2 + y^2 -9
Work out the length of the diameter

Answers

Answer 1

Answer:

d = 6 units

Step-by-step explanation:

If x^2 + y^2 = 9, x^2 + y^2 = 3^2 = r^2.  The radius is 3 and the diameter is twice that, or d = 6 units

We have:

ab = bc (hypothetical)

so the triangle ABC is isosceles at B

we have: bd is the height of the triangle ABC, so BD is perpendicular to AB

Consider the triangle ABD and the right triangle ACD have:

AB = BC (hypothesis)

BD is the common edge

So the triangle ABD = triangle ACD (hypotenuse - acute angle)

hence the angle ABD = angle ACD

The distance between each base on a baseball diamond is 70 feet. How far would a player have to throw the ball to get it from 1st base to 3rd base? Round your answer to the nearest tenth and label your answer.

Answers

Answer:

140

Step-by-step explanation:

From the 1st base to the 2nd base is 70 feet.

From 2nd base to 3rd base is 140 because 70×2=140.

Another way to do this is 70+70=140.

Hopefully this helps :)

One angle of a triangle measures 57° Which could be the other two angles of the triangle?
A. 48° and 75°
B. 57º and 57°
C. 63º and 70°
D. 70° and 83°

Answers

Answer:

A) 48° + 75°

Step-by-step explanation:

All triangles contain 180°

180° - 57° = 123°

A) 48° + 75° = 123°

B) 57° + 57° = 114°

D) 63° + 70° = 133°

A) 70° + 83° = 153°

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

The answer is A. 48 and 75

Thr sum of all triangles is 180

so, 180 57 = 123

The sum of other two angles should be 123,

so,...

48 + 75 = 123

Given:

The function is:

[tex]y=6x+3[/tex]

To find:

The missing value for the given table of values.

Solution:

We have,

[tex]y=6x+3[/tex]

Substituting [tex]x=1[/tex] in the given function, we get

[tex]y=6(1)+3[/tex]

[tex]y=6+3[/tex]

[tex]y=9[/tex]

Substituting [tex]x=3[/tex] in the given function, we get

[tex]y=6(3)+3[/tex]

[tex]y=18+3[/tex]

[tex]y=21[/tex]

Substituting [tex]x=6[/tex] in the given function, we get

[tex]y=6(6)+3[/tex]

a bucket that holds a volume
of 601 in. and has height 10.7 in. What is the radius of the bucket? Use
3.14 for .

Answers

Answer:

4.22in

Step-by-step explanation:

Given data

Volume= 601in^3

Height= 10.7in

Radius= ??

The expression for the volume of a cylindrical bucket is

V=πr^2h

substitute

601= 3.14*r^2*10.7

601= 33.598r^2

601/33.598= r^2

17.88=r^2

square both sides

r= √17.88

r= 4.22 in

Hence the radius of the bucket is 4.22in

Answer:

- the angle at H is 120 degrees

- the missing segment is DC

Step-by-step explanation:

The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .

Without instruction we can assume FGH is 120 degree.

This means GHF is 30 degrees to complete the triangle FGH.

So the angle around H, or JHG is 90 + 30 = 120 degrees

For the ratio, we can simply look at the comparison between the small figure   DJHGF

and the large figure DCBAE, and we see that the denominator

DJ in the small figure is DC in the large figure.

Duane’s scores on the first three math tests this quarter are 82, 74, and 96. Which is the lowest score he could get on the fourth test so that his average score will be at least 80 for the quarter?

Answers

Answer:

84

Step-by-step explanation:

(The sum of 82, 74, and 96 would be 252. And the count of numbers included in the question would be 3, and so you would divide the count from the sum as shown like Sum/Count. In this case it'd be 252/3, and that would equal 84.)

Average =  Sum/Count  

=   252/3  

=  84
