Answer:

(-8, 8)

Step-by-step explanation:

Plug in the y from the top equation into the y of the bottom equation

x² + (x + 16)² = 128

x² + x² + 32x + 256 = 128

Subtract 128 from both sides to make it equal to zero

2x² + 32x + 256 = 128

                 - 128    - 128

2x² + 32x + 128 = 0

Divide both sides by 2

(2x² + 32x + 128)2 = 0/2

x² + 16x + 64 = 0

Factor the equation

(x + 8)(x + 8) = 0

We see that x will have to be -8 for it to equal zero

so x = -8

Plug the new x into one of the original equations; let's use the top one

y = -8 + 16

y = 8

Answer:

  88

Step-by-step explanation:

Imagine a line through City Hall parallel to the given streets. The angle between that and the path to Euclid Street is 51°, congruent with the alternate interior angle marked 51°.

The angle between our imaginary line and the path to Lambert Street is 37°, congruent with the alternate interior angle marked 37°.

The value of x° is the sum of those two angles:

  x° = 51° +37°

  x = 88

__

Alternate solution

If you extend the path to Euclid Street until it intersects Lambert Street, the alternate interior angle theorem tells you the angle it makes with Lambert Street is 51°. The angle x° is an external angle to the triangle that now has 51° and 37° as remote interior angles. As such, x is the sum of 51 and 37:

  x = 51 +37 = 88

Since the other points are 0

Answer:

(-4,-6)

Step-by-step explanation:

If your point D were to start at (4,6), the first 90° clockwise rotation would have the point land on (4,-6), the second would have point D land on (-4,-6).  A faster way to do this without making 2 90° clockwise rotations, is you flip it diagonally across the center point, if the center point is 0, you would flip both signs (positive would become negative and the other way around).

The rotation of point about 180 degree is D(4, 6)----> D'(4, -6).

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have,

The points D(4, 6).

We know the rule for 180 degree rotation is

(x, y) ----> (x, -y).

So, the rotation of point about 180 degree is

D(4, 6)----> D'(4, -6).

Answer:

25

Step-by-step explanation:

First we need to create an equation. We’ll say the losing team scored x points. If the winning team scored 19 more, they would have x + 19 points. We know the total is 31 points, so we end up with x + x + 19 = 31, or 2x + 19 = 31. Subtract 19 from both sides to get 2x = 12. Divide both sides by 2, and get x = 6. To find out how much the winning team scored, which we know is x + 19, put 6 in for x and get 25.

Answer:

D

Step-by-step explanation:

A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r

for the sequence

- 3, 9 , - 27 , 81....

the common ratio r is

r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3

Then the recursive formula is

f(n) = - 3 f(n - 1) if n > 1

f(1) = - 3

option D

Answer:

D)

Step-by-step explanation:

A recursive formula always has two parts: the value of an initial term (or terms), and an equation defining [tex]a_n[/tex]​​ in terms of preceding terms.

From inspection, the initial term is -3

[tex]\implies a_1=-3[/tex]

[tex]\implies f(1)=-3[/tex]

From inspection, we can see that each term is the preceding term multiplied by -3.  Therefore, the sequence can be defined as:

[tex]a_n=-3(n-1)[/tex]

[tex]\implies f(n)=-3f(n-1)[/tex]

So the recursive formula for the sequence is D)

[tex]f(n)=\left \{ {{f(1)=-3} \atop {f(n)=-3f(n-1)}} \right.[/tex]

Answer: So the answer wont be C or D because it doesn't get over 43.2 inches of water so if you do 43.2 -- 1.8 it will equal 41.4 inches

MARK ME BRAINLIEST!!!!!!!!!!!!!!!

The city's mean annual rainfall is 40.5 inches, option A is correct.

It is a branch of mathematics that deals with the occurrence of a random event.

We know that P(z ≥ 1.5) = 0.0668

From the standard normal distribution table, we can find that the z-score corresponding to a right-tailed probability of 0.0668 is approximately 1.5. Therefore, we have:

z = 1.5

We can use the formula for the z-score:

z = (x - μ) / σ

where x is the observed value, μ is the mean, and σ is the standard deviation.

Substituting the given values, we get:

1.5 = (43.2 - μ) / 1.8

Solving for μ, we get:

μ = 43.2 - 1.8 × 1.5 = 40.5

Therefore, the city's mean annual rainfall is 40.5 inches.

Answer:

Step-by-step explanation:

8 times 15 is 120 then you multiple it to s which is 120s then you multiple 15 and 11 then 8 which is 1320 and then you divide 1320 with 120 then you get 11 as your answer

Answer:

Step-by-step explanation:

Answer:

a/

36s ~ 360º

1s ~ ?

so 1 * 360 / 36 = 10º

b/

36*3/4=27s (closest)

36*1/4=9s (farthest)

c/

20ft

Answer:

a) 10°

b) closest:  27 seconds

farthest: 9 seconds

c) 20 ft

Step-by-step explanation:

a) Angles around a point add up to 360°, therefore 1 rotation = 360°

If it makes one rotation in 36 seconds, then there are 10° per second as  360/36 = 10

b) closest to wall:  this will be a 3/4 rotation:

3/4 of 36 seconds = 0.75 x 36 = 27 seconds

farthest from wall:  1/4 rotation:

1/4 of 36 = 0.25 x 36 = 9 seconds

c) 18 seconds is half of 36 seconds.  Therefore, you will have made a 1/2 rotation.  So you will be on the same horizontal plane as the start position, but on the opposite side of the circle (see attached diagram).

Therefore, you will be 20ft away from the wall (shown in blue).

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 484 = 676 ( subtract 484 from both sides )

x² = 192 ( take square root of both sides )

x = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] in
