In which direction does the parabola y=x2−4x−5 open?

Answers

Answer 1

Answer:

upward

Step-by-step explanation:

The equation showing in the question is actually

[tex]y = x^{2} - 4x - 5[/tex]

After graphing this equation you can see that the parabola opens up pointing upwards with a vertex of (2, -9) . You can calculate the vertex of the parabola by substituting either y or x with 0 and then solving for the missing variable.

Oliver is 33 years older than his son. Eight years ago, Oliver's age is five more than thrice his son's present age. How old is Oliver now?


pls answer with solution :]​

Answers

Answer:

47

Step-by-step explanation:

Let us assume his son be x

So, the oliver age is x + 33

Now eight years ago, oliver age is 5 more than thrice his son present age

x - 8 = 5 + 3x

So,

33 + x = 5 + 3x

2x =28

x=14

o = 33+14 = 47

a point is chosen at random on AK. what is the probability that the point will be on CD. don't forget to reduce

Answers

Answer:

your answer is 1/10. hope this helps!

The probability that the point will be on CD will be 1/10 or 0.10.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

A point is chosen at random on AK.

The distance between A and K will be 20.

Then the probability that the point will be on CD will be

The distance between C and D will be 2.

Then the total event will be

Total event = 20

The favorable event will be

Favorable event = 2

Then the probability is defined as the ratio of favorable event and total event.

P = Favorable event / Total event

P = 2 / 20

P = 1 / 10

P = 0.10

Then the probability that the point will be on CD will be 1/10 or 0.10.

The function h(x)=x^2+3 and g(x)=x^2-6. If g(x)=h(x)+k, what is the values of k?

Answers

Answer:

The value of [tex]k[/tex] is -9.

Step-by-step explanation:

Let [tex]g(x) = x^{2}-6[/tex], we proceed to manipulate the expression algebraically to derive an expression equivalent to [tex]g(x) = h(x) + k[/tex], where [tex]h(x) = x^{2}+3[/tex].

[tex]g(x) = x^{2}+[(-9)+3][/tex] Definition of subtraction.

[tex]g(x) = (x^{2}+3)+(-9)[/tex] Commutative and associative properties.

[tex]g(x) = h(x) +(-9)[/tex]   [tex]h(x) = x^{2}+3[/tex]/Result

We notice that value of [tex]k[/tex] is -9.

The width of a rectangle measures (3v-3w) centimeters, and its length measures (5v-9w) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answers

Answer: The Perimeter of the rectangle, P= 16v −24w

Step-by-step explanation:

Perimeter of a rectangle  = 2( L +W) =   2L + 2W

The width of a rectangle is given as  (3v-3w) centimeters,

its length is given as (5v-9w) centimetres

The Perimeter,P will now be  = 2L + 2W

P=2( 3v-3w) + 2( 5v-9w)

P=6v  −6w + 10v  - 18 w

 adding like terms

P=6v + 10v  −6w −18 w

P= 16v −24w

A shipping container is in the shape of a right rectangular prism with a length of 2 feet, a width of 1.5 feet, and a height of 3.5 feet. The container is completely filled with contents that weigh, on average, 0.49 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?

Answers

Answer:

5 pounds

Step-by-step explanation:

the volume of the container = 2*1.5*3.5= 10.5cubic foot.

Density of the content = 0.49 pound per cubic foot.

As already know,

Density = mass/ volume.

therefore, mass = density * volume.

mass of the content = 0.49 * 10.5 =5 pounds approximately

Find the value of y. Be sure to keep the exact value (use square root and don’t round your answer).

Answers

Answer:

y = 8·√3

Step-by-step explanation:

From the drawing of the right triangle, we have;

The length of the opposite leg to the given 60° (reference) angle = 12

The length of the adjacent leg to given 60° (reference) angle = x

The length of the hypotenuse side = y

By trigonometric ratios, we have;

[tex]sin(Reference \, Angle) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

Therefore, we have;

[tex]sin(60^\circ) = \dfrac{12}{y}[/tex]

From the value of sin(60°), we have;

[tex]sin(60^\circ) = \dfrac{\sqrt{3} }{2}[/tex]

[tex]\therefore y= \dfrac{12}{sin(60^\circ) } = \dfrac{12}{\dfrac{\sqrt{3} }{2} } = \dfrac{2 \times 12 \times \sqrt{3} }{{{3} } } = \dfrac{24 \times \sqrt{3} }{{{3} } } = 8 \cdot \sqrt{3}[/tex]

y = 8·√3

[tex]\left(x= \dfrac{12}{tan(60^\circ) } = \dfrac{12}{{\sqrt{3} } } = 4\cdot \sqrt{3} \right)[/tex]

Step-by-step explanation:

15. 6.06

16. -7.21

17. 1.82

The required values of the given radials are √37 = 6.06, - √52 = -7.21, and √3.3 = 1.82.

What is Square Root?

The number's square root is that component of a number that, when multiplied by itself, generates the original number. Special exponents are squares and square roots.

The square root of 37 lies between the square root of 36 and the square root of 49. Hence, √36 < √37 < √49 ⇒ 6 < √37 < 7

Divide 37 by 7. 37 ÷ 7 = 5.28

Find the average between 5.28 and 7.

(5.28 + 7)/ 2 = 12.28 /2 = 6.06

Thus, √37 ≈ 6.06

- √52 = - √(2 × 2 × 13)

- √52 = - 2√13

- √52 = - 2 × 3.605

- √52 = - 7.21111

- √52 = - 7.21

√3.3 = 1.82

Thus, the required values of the given radials are √37 = 6.06, - √52 = -7.21, and √3.3 = 1.82.

Answers

Answer:

62 kg

Step-by-step explanation:

Weight loss equation for sultan :

Y = 70 - 2x

Y = weight in kilogram ; x = number of months

Sultan's weight after 4 months

Put 4 in x in the equation and calculate the value of y

Y = 70 - 2(4)

Y = 70 - 8

Y = 62kg

Weight after 4 months is 62 kg
