​  =10.5 right per left

At East Middle School, there are

Answer:

the width is 30

Step-by-step explanation:

first if the width was there you would multiply it ( the width ) with the length to find the area so you simply do the opposite , divide you should divide 240 with 8 and that's going to make 30 ( the width )

Answer:

  [tex](\sqrt{8},0)\\(-\sqrt{8},0)[/tex]

Step-by-step explanation:

x² – 2x + 3 = -2x + 12

    +2x    -3      +2x  -3

                x²=8

         [tex]\sqrt{x^{2} } =\sqrt{8}[/tex]

           [tex]x=\sqrt{8}[/tex]

Hi there!

Looking at the graph, we can see zeroes at x = -4, 0 (bounce, degree of 2) and 3. The graph is also face up, so it is positive. We can write an equation in factored form:

f(x) = x²(x + 4)(x - 3)

Find the equation of g by translating each zero left. The new zeros would be:

x = -6, x = -2, and x = 1

Write the polynomial:

g(x) = (x + 2)²(x + 6)(x - 1)

Answer:

f(x)= x²(x+4)(x-3), g(x)= (x+2)²(x+6)(x-1)

Step-by-step explanation:

you have the roots at -4,0, and 3

look at what the graph is doing at those points and see that

-at -4 and at 3 the graph crosses the x-axis so in the equation you will have (x-root)

-at 0 the graph is touching the x-axis and then goes back above/under it so in the equation you will have (x-root)²

f(x)= x²(x+4)(x-3)

g(x) left 2 units

when you move a function to the left/ right you add/subtract that amount to the value of x so

g(x)= (x+2)²(x+2+4)(x+2-3)

g(x)= (x+2)²(x+6)(x-1)

It's 8/25.

The reason its 8/25 is because u gotta add or subtract.

Answer:

irrational number i believe

Step-by-step explanation:

Answer:

a) 3.125feet

b) 95.3cm

Step-by-step explanation:

a) Let the flamingo leg length be l

Let the body length be b

If a flamingo's leg length is proportional to its body length then;

l ∝ b (direct proportionality)

l = kb

k is the constant of proportionality

If a flamingo with a body length of 1.2 feet has a leg length of 2.5 feet, then;

when b = 1.2, l = 2.5

Substitute into the formula

2.5 = 1.2k

k =2.5/1.2

k = 2.083

We ate to find l when b = 1.5

Since l= kb

l = 2.083(1.5)

l = 3.125feet

Hence the leg length of a flamingo is 3.125feet to the nearest thousandths

b) Convert 3.125feet to centimeters

Using the conversion factor

1foot =30.48cm

3.125feet = x

Cross multiply

x = 30.48×3.125

x = 95.25cm

Hence the length length in cm to nearest tenth is 95.3cm

Answer:

greatest- angle A smallest- angle B

Step-by-step explanation:

the angle across from the greatest side is the greatest angle. same for the smallest side and angle.

Answer:

Angle A would be the greatest, while angle c would be the smallest

Step-by-step explanation:

Angle ∠A = 71.801°

Angle ∠B = 47.347°

Angle ∠C = 60.852°

Answer:

X = 3

Step-by-step explanation:

Given the expression :7x - 3 = 18

To obtain the solution set ; we solve for X in the equation ;

7x - 3 = 18

Add 3 to both sides

7x - 3 + 3 = 18 + 3

7x = 21

Divide both sides by 7

7x / 7 = 21 / 7

x = 3

Hence, x = 3

Answer:

x=3

Answer: C. 124

Step-by-step explanation:

In parallelograms, any two consecutive interior angles add to 180 degrees. CDA and BCD are consecutive interior angles. Since the measure of angle CDA is 56 and the sum of CDA and BCD equal 180, then to find the value of BCD, evaluate 180-56.

180 - 56 = 124

Given:

All the edges of a cube are expanding at a rate of 4 in. per second.

To find:

The rate of change in volume when each edge is 10 in. long.

Solution:

Let a be the edge of the cube.

According to the question, we get

[tex]\dfrac{da}{dt}=4\text{ in./sec}[/tex]

[tex]a=10\text{ in.}[/tex]

We know that, volume of a cube is

[tex]V=a^3[/tex]

Differentiate with respect to t.

[tex]\dfrac{dV}{dt}=\dfrac{d}{dt}a^3[/tex]

[tex]\dfrac{dV}{dt}=(3a^2)\times \dfrac{da}{dt}[/tex]

Putting the given values, we get

[tex]\dfrac{dV}{dt}=(3(10)^2)\times 4[/tex]

[tex]\dfrac{dV}{dt}=3(100)\times 4[/tex]

[tex]\dfrac{dV}{dt}=300\times 4[/tex]

[tex]\dfrac{dV}{dt}=1200\text{ in}^3\text{/sec}[/tex]

Therefore, the rate of change in volume 1200 cubic inches per second.

[tex]38.07 = \frac{9}{100} x[/tex]

[tex]38.07 \times \frac{100}{9} = x[/tex]

[tex] \frac{3807}{9} = x[/tex]

[tex]423 = x[/tex]

Answer:

423

Step-by-step explanation:

Use proportions to get (38.07/9) = (x/100). Cross multiply to get 3807 = 9x. Divide 3807 by 9 to get 423.

Answer:

The answer is x>-4     (brainiest please)

Step-by-step explanation:

Add 38 to both sides

-6x-36+36>-12+36

-6x>24

multiply both side by -1

(-6x)(-1)<24(-1)

6x>-24

simplify

6x/6<24/6

x<-4
