The diagram is missing, so i have attached it.

Answer:

-1000 ft

Step-by-step explanation:

From the diagram attached, we see that they went 1000 ft below the sea level.

Now an altimeter is used to measure altitude depth of an object relative to a fixed level which in this case the fixed level is the top of sea. Since the depth in this case is below sea level, it will be negative.

Thus,the altimeter will read -1000 ft

Answer:

The dolphins are shown 1,000 feet below sea level. The altimeter reading would be -1,000 feet.

Answer:

1 and 3

Step-by-step explanation:

it is where the graph meets the x axis line

Answer:

Slope = -3, Y-intercept = -2, y = -3x -2

Step-by-step explanation:

There are multiple points plotted on the graph, but right now, we only need to focus on two.

(-2, 4) (-1, 1)

Using the ordered pairs, do delta y/ delta x to get the slope

(1-4)/(-1-(-2)

(-3)/(-1+2)

(-3)/(1)

Slope = -3

y = -3x + b

As shown on the graph, the y-intercept is -2. It is when x = 0

So, for the equation, substitute the found values.

y = -3x -2

Answer: a parallelogram

Answer:

C.

Step-by-step explanation:

14/3 = 4.66

/2/=2.33

-14/4 = -3.5

So the numbers are 4.66, 4.3, 2.33, 1.3, -2 and -3.5

So the numbers are -14/4, -2, 1.3,/2/, 4.3, 14/3

Answer:

6 is the answer for your box :) Double checked :)

Step-by-step explanation:

25.12 = 1/3(12.56h)

multiply both sides by 3 to get rid of the fraction

75.36 = 12.56h

divide both sides by 12.56

6 = h

h = 6

Answer:

h = 6

Step-by-step explanation:

25.12=12.56/3 h

25.12 x (3/12.56) = h

h = 6

Answer:

Final answer:  x=0 m:3 and x=-6 m:2

Step-by-step explanation:

1. 4x³(x²+12x+36)- Divide by greatest common factor, to simplify.

2. 4x³(x+6)(x+6)- Factored

3. 4x³ = 0   Set each factor equal to zero

4. x+6=0       x+6=0

So, x= -6, two times, mulitiplicity 2

So, 4x³=0, so x=0 three times, mulitiplicity 3

Final answer:  x=0 m:3 and x=-6 m:2

Answer:

10

Step-by-step explanation:

to find the answer for 3y + 4 we have to find the value of y.

we can find that by using the second equation.

-2y+6=2

-2y+6-2 =0 (subtract 2 from both the sided)

4= 2y (we will bring the -2y to the other side of the equation and then subtract the 6-2 to get the 4)

4/2=y  (divide by 2 on both the sides)

∴ y=2

now we will plug in the y of value that we see as -2 into the first equation.

∴ 3y+4 will become

=  3(2)+4

=6+4

=10

Answer:

The length of BC is 3.61 units.

Step-by-step explanation:

√13=3.60555128=3.61 (Round off to two places)

According to Pythagoras theorem,

Hypotenuse²=Perpendicular²+Base²

H²=P²+B²

Perpendicular given=3 units

Base given=2 units

H²=3²+2²

H²=9+4

H²=13

H=√13 units

H=3.61 units (approx)

Answer:

a) the new perimeter is 2 times the old perimeter

b) the new area is 4 times the old area

Step-by-step explanation:

b) the doubling of the length and width affects the area formula like this:

old triangle area formula = 1/2bh

new triangle area formula = 1/2(2b)(2h),   you see the 2 x 2 causes the area to be 4 fold

Answer:

Your answer is 27

I hope I helped, would appreciate brainliest! ;)

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

27% = 27 'out of one hundred',

p% is read p 'percent',

27% = 27/100 = 27 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 100 by 27%

27% of 100 is equivalent to multiplying them:

27% × 100 = ?

27% × 100 =

(27 ÷ 100) × 100 =

(27 × 100) ÷ 100 =

2,700 ÷ 100 =

27

Proof.

How do we check the result?

If 27% × 100 = 27 =>

Divide 27 by 100...

... And see if we get as a result: 27%

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

n/100 = n%, any number.

Calculate the percent value:

27 ÷ 100 =

0.27 =

0.27 × 100/100 =

(0.27 × 100)/100 =

27/100 =

27%

So we have proved that the calculations are correct.

Answer:

Answer:

The number could be [tex]-7.5[/tex] or [tex]8[/tex].

Step-by-step explanation:

I'm going to assume this means "The square of a number is 60 greater than half of the number." Let the number be [tex]x[/tex]. The square of [tex]x[/tex] will be [tex]x^{2}[/tex]. "is" denotes that we use the "[tex]=[/tex]" sign, so our equation so far is [tex]x^{2} =[/tex] . Half of [tex]x[/tex] is [tex]\frac{1}{2}x[/tex], and "greater than" implies addition, so [tex]60[/tex] greater than [tex]\frac{1}{2}x[/tex] is [tex]\frac{1}{2}x+60[/tex]. Therefore, the equation is [tex]x^{2} =\frac{1}{2}x+60[/tex].

Solving for [tex]x[/tex], we get:

[tex]x^{2} =\frac{1}{2}x+60[/tex]

[tex]2x^{2} =x+120[/tex] (Multiply both sides of the equation by [tex]2[/tex] to get rid of the fraction)

[tex]2x^{2} -x-120=0[/tex] (Subtract [tex]x+120[/tex] from both sides of the equation to make it easier to solve)

[tex]2x^{2} +15x-16x-120=0[/tex] (Split [tex]-x[/tex] into [tex]15x-16x[/tex] to make the LHS easier to factor)

[tex]x(2x+15)-8(2x+15)=0[/tex] (Take a common factor out of the first two terms and the last two terms)

[tex](2x+15)(x-8)=0[/tex] (Take another common factor out)

[tex]2x+15=0,x-8=0[/tex] (Zero Product Property)

[tex]x=-7.5,8[/tex] (Solve)

Hope this helps!

Answer:

C. [tex]\sqrt{3x^2+21x}[/tex]

Step-by-step explanation:

When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.

[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]

y-yi=m(x-xi)

y-3=1/4(x-4)

y-3=x-4/4

4y-12=x-4

4y+x-12+4=0

4y+x-8=0

so the equation of

the line perpendicular

to

y=1/4-5 through

the point(4,3)

is4y-x-8=0

Given:

The expression is

[tex]2\times 2\times 2\times 2\times 2[/tex]

To find:

The index notation of the given expression.

Solution:

Index: The power of a number and a variable is called its index.

Index notation: The expression which has a base and a power.

In the given expression 2 is multiplied 5 times, so by using the property of exponent we get

[tex]2\times 2\times 2\times 2\times 2=2^{1+1+1+1+1}[/tex]       [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]2\times 2\times 2\times 2\times 2=2^{5}[/tex]

Therefore, the index notation of the given expression is [tex]2^5[/tex].

Answer:

y = 2

Step-by-step explanation:
