Which of the following is the graph of y = -x^2 - 1?

Answer:

the missing angle is 46.8

Step-by-step explanation:

since all the angles in a triangle add up to 180, you can do the sum of the numbers that we know and subtract by 180

43.2+90= 133.2

180-133.2=46.8

so the missing angle is 46.8

we cant solve the sides of the triangle correctly without at least two known sides, and we only have one.

i hope this helps :)

The sides of the right triangle are AB = 2.27 m, BC = 3.2 m, and AC = 3.62 m.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We are given that Angle B = 43.2 degrees, Angle C = 90 degrees and Side BC = 3.2 m

First, we can use the fact that the sum of the angles in a triangle is 180 degrees to find angle A:

Angle A = 180 degrees - Angle B - Angle C

Angle A = 180 degrees - 43.2 degrees - 90 degrees

Angle A = 46.8 degrees

Next, we can use the sine ratio to find the length of side AB:

sin(A) = opposite / hypotenuse

sin(46.8 degrees) = AB / 3.2 m

AB = sin(46.8 degrees) x 3.2 m

AB = 2.27 m

Finally, we can use the Pythagorean theorem to find the length of side AC:

AC² = AB² + BC²

AC²  = (2.27 m)² + (3.2 m)²

AC² = 13.15 m²

AC = sqrt(13.15) m

AC = 3.62 m

Therefore, the sides of the right triangle are AB = 2.27 m, BC = 3.2 m, and AC = 3.62 m.

Answer:

Answer to question 1 is 190 small pumpkins and 160 large pumpkins.

Answer to question 4 is 7 bags.

Step-by-step explanation for question 1:

190 = Small pumpkins

160 = Large pumpkins

190+160 = 350

So If you do 190 x 2 = £380

and 160 x 5 = £800

and 800+ 380 = £1,180

So Sal sold 190 small pumpkins and 160 large pumpkins!

Step By Step explanation for question 4:

£3.77x7= 26.39

£3.18x5=15.9

26.39+15.9 = 42.29.

So he bought 7 bags of £3.77 for his candys !

Answer: Yes 0.56 could be a probability

Explanation:

The value 0.56 is between 0 and 1, which is a key important characteristic of any probability. It's the same as saying 56% is between 0% and 100%; where 0% represents the event not happening and 100% means the event is guaranteed to happen.

Answer:

m<QTP= 45.5º

Step-by-step explanation:

180-89=91

since it is parallel ÷2

91÷2=45.5

Answer:

<QTP = 43 degrees

Step-by-step explanation:

5x - 32 = 3x (corresponding angles)

5x - 3x = 32

2x = 32

x = 32/2

x = 16

5x - 32 = 5(16)-32 = 48

< QTU = 89 (corresponding angles)

180- 89 - 48 = <QTP

43 degrees

Answer:

Step-by-step explanation:

[tex]2^{4-6x}=8^{1-x}\\\\2^{4-6x}=(2^{3})^{1-x}\\\\2^{4-6x}=2^{3*(1-x}}\\\\2^{4-6x}=2^{3-3x}[/tex]

Bases are equal, so compare the powers,

4 - 6x = 3 - 3x

Subtract 3 from both sides,

4 - 3 - 6x = -3x

1 - 6x = -3x

Add 6x to both sides

1 = -3x+ 6x

1 = 3x

Divide both sides by 3

Step-by-step explanation:

Let p represent the number of pigs. Then the number of ducks is 38-p and the number of legs is ...

  4p +2(38 -p) = 92

  2p = 16 . . . . . . . . . . . . collect terms, subtract 76

  p = 8 . . . . . . 8 pigs in the field

  38-p = 30 . . . number of ducks in the field

There are 30 ducks and 8 pigs in the field.

For BC:

5x+28=7x-4

5x+32=7x

32=2x

x=16

Hope This Helps!!!

Answer:

x = 16

Step-by-step explanation:

(7x - 4) and (5x + 28) are alternate exterior angles and are congruent, so

7x - 4 = 5x + 28 ( subtract 5x from both sides )

2x - 4 = 28 ( add 4 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Answer:

The building is 95.6159m tall.

Step-by-step explanation:

Both the pole and the building should have the same ratio of height to shadow length so we can come up with the equation:

[tex]\frac{2.6}{1.38}[/tex] = [tex]\frac{x}{50.75}[/tex]

Then solve for x, it will correspond to the height of the building.

x = 50.75([tex]\frac{2.6}{1.38}[/tex])

x = 95.6159m

Answer:

Step-by-step explanation.

Yes, there is another description of the pattern that will give the same first three numbers but will lead to a different pattern.

While the student's claim of each number being two times the previous number holds true for the first three numbers (1, 2, and 4), there could be an alternative pattern such as an arithmetic progression.

If we consider the pattern as an arithmetic sequence with a common difference of 1, the first three numbers will be 1, 2 and 4 but the subsequent numbers in the pattern would differ as the arithmetic sequence would continue as 1, 2, 3, 4, 5,.....

Answer:

16/33

Step-by-step explanation:

2 4/3 --> 10/3

10/3 x 8/55

80/165 --> divide by 5

16/33

Answer:

[tex]\frac{16}{33}[/tex]

Step-by-step explanation:

When you're having trouble dividing, use the "keep, change, flip" method. First reduced the fractions:

2 4/3 --> 10/3

6 7/8 --> 55/8

The problem should not be: [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{55}{8}[/tex]

For "keep, change, flip", keep [tex]\frac{10}{3}[/tex] as normal, change the division symbol into a multiplication symbol (it's opposite), and flip [tex]\frac{55}{8}[/tex] to make [tex]\frac{8}{55}[/tex]

The problem should now be: [tex]\frac{10}{3}[/tex] × [tex]\frac{8}{55}[/tex]

Now multiple to get: [tex]\frac{80}{165}[/tex]

And reduce to get: [tex]\frac{16}{33}[/tex]
