A triangle has an angle that measures 95°. The other two angles are in a ratio of 6:11. What are the measures of those two angles?

Answer:

g(x) = - 16x² + 4

Step-by-step explanation:

Given the model:

First drop:

h(x) = - 16x² + 64

Second drop hits the ground 1.5 seconds sooner

Function g(x) to model the second drop:

-16t² + V0t + h0

h(x) = - 16x² + 64

0 = - 16x² + 64

16x² = 64

x² = 64/16

x = 2

1.5 seconds sooner :

X = 2 - 1. 5

x = 0.5

0 = - 16(0.5)² + 0 + h0

0 = - 4 + h0

h0 = 4

Hence,

g(x) = - 16x² + 4

Using it's concept, it is found that there is a 0.3482 = 34.82% probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that 13 out of 28 students did not earn an A on the final course, and 21 out of 28 students did not earn an A for the entire course, hence:

[tex]p = \frac{13}{28} \times \frac{21}{28} = 0.3482[/tex]

0.3482 = 34.82% probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course.

Answer:

Step-by-step explanation:

You want to identify the expressions equivalent to 11x -4x +6x and 3(1 +9y).

We can identify the equivalent expressions by putting them all in their simplest form. This means using the distributive property to eliminate parentheses, and combining like terms.

The simplified version of the given expression is ...

  (11 -4 +6)x = 13x

The other expressions simplify to ...

  7x +6x = (7+6)x = 13x . . . equivalent

  7x -6x = (7 -6)x = 1x = x . . . not equivalent

  13 +x (already simplest) . . . not equivalent

  13x (already simplest) . . . equivalent

The simplified form of the given expression is ...

  3·1 +3·9y = 3 + 27y

The other expressions simplify to ...

  3 +1·3 +9y = 6 +9y . . . not equivalent

  3 +27y . . . equivalent

  3·1 +3·9y = 3 + 27y . . . equivalent

  3 +9y (already simplest) . . . not equivalent

Answer:

[x - 5]² + [y + 7]² = 6²

Step-by-step explanation:

It should be noted:

"h" represents the x coordinate of the center point, "k" represents the y coordinate of the center point, and "r" represents the radius of the circle.

When the values are substituted:

[x - 5]² + [y - (-7)]² = 6²

⇒ [x - 5]² + [y + 7]² = 6² = 36

Step-by-step explanation:

Step-by-step explanation:

just add all the given angles and equate it with 540° and then find x

x/2 + x/2 + x - 25 + 100 + x - 15 = 540°

3x + 60 = 540°

3x = 540 - 60

x = 480/3

x = 160°

on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.

The relationship between the variables x, y and z is an illustration of similar triangles

The values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]

Right triangles are triangles with an angle measure of 90 degrees, and we have the following equivalent ratio from the triangle

[tex]x : 9 = 4 : x[/tex]

Express as fraction

[tex]\frac x9 = \frac 4x[/tex]

Cross multiply

[tex]x^2 = 36[/tex]

Take the square root of both sides

[tex]x = 6[/tex]

The value of y is then calculated using the following Pythagoras theorem

[tex]y = \sqrt{9^2 + x^2[/tex]

This gives

[tex]y = \sqrt{9^2 + 6^2[/tex]

[tex]y = \sqrt{117[/tex]

The value of z is then calculated using the following Pythagoras theorem

[tex]z = \sqrt{4^2 + x^2[/tex]

This gives

[tex]z = \sqrt{4^2 + 6^2[/tex]

[tex]z = \sqrt{52[/tex]

Hence, the values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]

Answer:

Step-by-step explanation:

When the balloons collide, they have the same x and y:

-3x^2 + 24x + 3 = y = -4x^2 + 25x + 15

Rearranging like terms together:

(4x^2 - 3x^2) + (24x - 25x) + (3 - 15) = 0

x^2 - x - 12 = 0

(x - 4)(x +3) = 0

x = 4 or -3

As x represents time, it cannot be negative.

The time when the balloons collide is at 4.00 seconds.

The collision means that y is equal

So

As it's time so must be positive

x > - 10 / -4

- 10 / -4 = 10 / 4 = 5/2

x > 5/2

Answer:

The pyramid consists of 4 triangles having bases of 3 km and height of 4 km (measured along the face)

A = 4 * 3 / 2 * 4 = 24 km^2

Each triangle has an area of 1/2 * bottom length * height

3 cannot refer to the length of one of the isosceles triangles because a slant height of 4 km is given and is less than one such side

The surface area of the square pyramid is 24 km².

The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.

Mathematically, it can be expressed as:

Surface Area S.A = P × l/2

where;

Surface Area (S.A) = 12 × (4/2)

Surface Area (S.A) = 24 km²

The solution of (2,5) indeed equals the solution of the equation y=2x+1

Step-by-step explanation:

to solve just plug in the values.

y=2(2)+1 which gives us the y value of y=5

to solve for x, plug in y. 5=2x+1.

subtract 1 from both sides, and you get 4=2x

then divide 2 on both sides to get x, which is 2. therefore this is true.

Answer:

$2.22

Step-by-step explanation:

First, we know that the cost of one mailing letter is $0.23 per once, plus $0.14.

Our formula is: c = 0.23w + 0.14

Let's rewrite our variables to the way it's suppsed to be.

C = cost

W = weight ounces.

Now, we have to add 0.23 plus 0.14 to get our cost.

That equals 0.37.

Now that we know that our cost for one letter is 0.37, we have to multiply

it by 6, because we are trying to figure out the cost of mailing a 6 ounce letter.

0.37 × 6 = 2.22

In conclusion, the cost of mailing a 6 ounce letter is $2.22
