Answer:

what grade you in

this looks like 4th grade

Answer:

4.25

Step-by-step explanation:

-x^2 + 3x + 2 = 0

Divide by -1

X^2 -3x - 2 = 0

x^2-3x+ =2+2.25

(x-1.25)-4.25

(x-1.5)

Answer:

The required expression for the depth is [tex]5.5t[/tex] feet.

The depth after 1.3 minutes is 71.5 feet.

Step-by-step explanation:

Let d be the depth of the sea below the surface of the water.

The rate of descending or the rate of increasing the depth, [tex]r= 5.5[/tex] feet/min.

Since, the rate is constant, so,

If the diver reaches the depth, [tex]d[/tex], in time, [tex]t[/tex]. So,

[tex]r= d/t[/tex]

[tex]\Rightarrow d=r\times t[/tex]

So, for [tex]r=5.5[/tex] feet/min, the required expression for the depth is [tex]5.5t[/tex] feet.

After time t= 1.3 minutes.

The depth, [tex]d = 5.5 \times 1.3 = 71.5[/tex] feet.

Step-by-step explanation:

Answer:

17 years

Step-by-step explanation:

hope it helps:)

Answer:

20 Years.

Step-by-step explanation:

As you could see my friend owned a dog for 9 years, and it reads that it is one year less which is 10 years since 10-1 (aka one year) equals 9 so anyways we know it's 10, and it's twice as long 10 x 2 (aka twice). which is how I got my answer... 20!  

Answer:

In an equilateral triangle, all three sides are the same length. An equilateral triangle is always equiangular. In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute.

Answer:

No, the administrator is wrong.

[tex]Adult = 500[/tex]

Step-by-step explanation:

Given

[tex]Total = 931[/tex]

[tex]Children = 423[/tex]

[tex]Adult = 408[/tex]

Solving (a): Is the administrator correct?

No, the administrator is wrong.

This is so because: when the number of children is subtracted from the total patient, the remaining number is not 408

Solving (b): Estimate the number of adults

By rounding up:

[tex]Adult = Total - Children[/tex]

Actual Figures

[tex]Adult = 931 - 423[/tex]

Round up

[tex]Adult = 900 - 400[/tex]

[tex]Adult = 500[/tex] -- approximately

Answer:

Step-by-step explanation:

Given that Nadya's uses the service for up to 200 times then

let let c represent the cost of Nadya's bill

and m be the minutes of airtime

therefore

the initial charger is $35

The charge per additional minutes is $0.23

c=35+0.23m

Therefore the expression is

c=35+0.33m

Answer:

(real number)

Answer:

12,5 centimeters.

Step-by-step explanation:

We take the following proportion

[tex]\frac{1 cm}{80m} = \frac{x}{1000m}[/tex]

Which becomes:

[tex]1000 = 80x[/tex]

And then, we clear out the variable x:

[tex]\frac{1000}{80}=\frac{100}{8}=\frac{50}{4}=12,5[/tex]

And this means that the width of the lake on the scale drawing will be 12.5 cm.

Step-by-step explanation:

Do you mean, what's the base in "-(-6)^5

If so it's -6!

Answer:

1. Putting  x = 0.5, y = -1/10 gives  0.44

2. Putting  x = -1, y = -3  gives 14

3. Putting x =3/4 , y = 2/5 gives 1.665

4. Putting  x = 0, y = 2.5 gives - 11.25

5.  Putting x = √2, y = √2 gives 17

6. Putting x = 2, y = -1  gives - 1

Step-by-step explanation:

-3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2

1. Putting  x = 0.5, y = -1/10

-3(0.5)^2 + 2(-1/10)^2 + 5(-0.05) - 2(-1/10) + 5(0.5)^2 - 3(-1/10)^2

= -0.75 +0.02 - 0.25 +0.2 + 1.25- 0.03

= 0.44

2. Putting  x = -1, y = -3

-3(-1)^2 + 2(-3)^2 + 5(3) - 2(-3) + 5(-1)^2 - 3(-3)^2

= -3 +18 +15+6+5-27

= 14

3. Putting x =3/4 , y = 2/5

-3(3/4)^2 + 2(2/5)^2 + 5(6/20) - 2(2/5) + 5(3/4)^2 - 3(2/5)^2

=- 27/16 +8/25 +30/20 -4/5 +45/16 - 12/25

= 18/16 - 24/25 + 30/20

= 18/16 - 96+150/100

= 18/16 +54/100

= 1800+ 864/1600

= 2664/1600

=1.665

4. Putting  x = 0, y = 2.5

-3(0)^2 + 2(2.5)^2 + 5(0) - 2(2.5) + 5(0)^2 - 3(2.5)^2

= 12.5 - 5.0 - 18.75

= -11.25

5.  Putting x = √2, y = √2

-3(√2)^2 + 2(√2)^2 + 5(√2.√2) - 2(√2) + 5(√2)^2 - 3(√2)^2

= -6 +4+10-4+19-6

= 17

6. Putting x = 2, y = -1

-3(2)^2 + 2(-1)^2 + 5(-2) - 2(-1) + 5(2)^2 - 3(-1)^2

= -12+2 -10 +2 +20 -3

= -1

Answer:

The toy rocket will return to the ground at 8.44 seconds

Step-by-step explanation:

The height h of the toy rocket launched vertically as a function of the time t is given by:

[tex]h(t)=-16t^2+135t[/tex]

The rocket will return to the ground when h=0:

[tex]-16t^2+135t=0[/tex]

Factoring:

[tex]t(-16t+135)=0[/tex]

There are two solutions:

t=0, t = 135/16 = 8.4375

The first solution corresponds to the moment the toy rocket was launched, the second is the time taken by the rocket to return to the ground.

The toy rocket will return to the ground at 8.44 seconds
