Answer:

y = 9x

Step-by-step explanation:

Answer:

4.5x          OR           9/2x

Step-by-step explanation:

We know this is a lineasr equation isnce it is a straight line and goes by a slope factor.

We know that for every change in 9 on the y axis, there is a change of two on the x- axis. This slope is now 9/2

The equation can be 9/2x OR 4.5x depending on whether your teacher will accept decimal answers or fractional answers.

Answer:

4

Step-by-step explanation:

All you need to do is plug in each value for x & then solve the equation to see if it equals 7.  When a number, like 2, is next to an x you multiply the two of them.  So when you substitute a number for x, you multiply it by the 2.

2(3)-1= 5

2(4)-1= 7

2(5)-1=9

Answer: x = 1/4

Step-by-step explanation:

Lo primero que harías es restar 7 de ambos lados de la ecuación debido a tu propiedad de igualdad, que te permite hacer esto.

24x+7=13

      -7   -7

24x=6

Ahora lo que harás es dividir ambos lados entre 24 para que puedas aislar x.

24x=6

/24    /24

x=6/24

Finalmente, puedes simplificar la fracción dividiendo el numerador y el denominador por 6.

x=6/6  /  24/6

x=1/4

It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.

It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.

We have:

The height of the Sharon from the diving board = 18 feet

The initial upward velocity of the Sharon = 4 ft/s

The height of the Megan from the ground = 5 feet

The initial upward velocity of the beach ball = 16 ft/s

We know the equation of motion is given by:

[tex]\rm h(t) = x + ut+\frac{1}{2} gt^2[/tex]

Put x = 18 feet and u = 4 ft/s in the above equation, we get:

[tex]\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2[/tex] ....(1)     [g = 9.8 m/s²]

Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:

[tex]\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2[/tex]  ....(2)

Equate the equation (1) and equation (2), we get

[tex]\rm 18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\[/tex]

18 + 4t = 5 + 16t

12t = 13

t = 1.08 seconds

Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.

Answer:

V ≈ 258 ft³

Step-by-step explanation:

I given the diameter d= 7.9 ft so the radius is r = d/2 = 7.9/2  ft

Volume of a sphere is

V = (4/3) π·r³ = (4/3) · π · (7.9/2)³ = 258.1546167 ft³

Answer:

12 ft ^3

Step-by-step explanation:

I assume you are looking ofr the volume of this pyramid

V = 1/3 base area * height

base area = area of 3-4-5 triangle =  1/2 * 3 * 4 = 6   ft^2

so Volume is :

1/3  * 6 * 6 = 12 ft^3

The circle can be illustrated by its equation, and the equation that represents the circle is (x + 4)² + (y - 9)² = 5²

The center of the circle is given as:

Center, (a,b) = (-4,9)

The diameter is given as:

d = 10

Calculate the radius (r)

r = 10/2 = 5

The circle equation is then calculated using:

(x - a)² + (y - b)² = r²

So, we have:

(x + 4)² + (y - 9)² = 5²

Hence, the equation that represents the circle is (x + 4)² + (y - 9)² = 5²

C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.

Step-by-step explanation:

Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.

Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.

Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.

Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.

Answer:

G

Step-by-step explanation:

really look at the position of point A on the number line.

it is a little bit to the right of -2, but clearly to the left of -1 and especially 0.

so, A must be negative.

that eliminates already H and J.

remember, that e.g. -2 < -1.

so, seemingly "adding" something to the description of a value of a negative number makes that negative number even smaller.

-1 7/8 is for example NOT the same as -1 + 7/8.

it is the same as

-1 - 7/8 = -1 7/8

so, -1 7/8 is indeed smaller than -1.

but it is still larger than -2 (e.g -1 8/8 = -2).

therefore, only G makes sense.

The quotient of the provided division in which binomial is divided by a quadratic equation is x+2.

Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The given division expression is,

[tex]\dfrac{x^2+3x+2}{x+1}[/tex]

Let the quotient of this division problem is f(x). Thus,

[tex]f(x)=\dfrac{x^2+3x+2}{x+1}[/tex]

Factor the numerator expression as,

[tex]f(x)=\dfrac{x^2+2x+x+2}{x+1}\\f(x)=\dfrac{x(x+2)+1(x+2)}{x+1}\\f(x)=\dfrac{(x+2)(x+1)}{x+1}\\f(x)={x+2}[/tex]

Finding the angle [tex]\theta[/tex]

[tex] \displaystyle { \sin}^{ - 1}( \sin( \theta) )= { \sin}^{ - 1} \bigg(\frac{ \sqrt{3} }{2} \bigg )[/tex]

Answer:

63.59 in²

Step-by-step explanation:

The formula to find the area of a square: a², where a is the side.

The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).

1) Find the diameter of the circle. The side of a square is the diameter.

a²

a = √81

a = 9

2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).

= 3.14 x 4.5²

= 3.14 x 20.25

= 63.585

3) Round off the result to the nearest hundredth.

= 63.59

The largest circle possible from the square piece of yellow felt material to create a sun for her art project is of area 63.585 square inches.

Area is the quantity that expresses the extent of a region on the plane or on a curved surface

According to the question

Square piece of yellow felt that has an area = 81 square inches

Now ,

Area of square of yellow felt =  81 square inches

⇒     [tex]Side^{2} = 81[/tex]

⇒      Side = ± 9      (where -ve 9 cannot be side )

⇒      Side =  9      

The largest circle possible from the material is

where, side of square = diameter of circle  ( figure attached )

        ⇒  9   = diameter of circle

       ⇒   9 = 2r

       ⇒   [tex]\frac{9}{2}[/tex] = r or  r = 4.5

Area of circle = [tex]\pi r^{2}[/tex]

                      =  3.14 * 4.5 * 4.5

                     = 63.585 square inches.

Hence, Area of the largest circle cut from the  square piece is of 63.585 square inches.
