Answer:

1107 feets below sea level

Step-by-step explanation:

Given that :

Initial elevation of submarine = 984.6 feets below sea level

Depth of dive from initial elevation = 122.4 feets below sea level

The elevation after the dive :

Initial elevation + depth of dive

984.6 + 122.4

= 1107 feets below sea level

Answer: 18.8 miles

Step-by-step explanation:

Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:

4.7x = 2.5x + 8.8

Collect like terms.

4.7x - 2.5x = 8.8

2.2x.= 8.8

x = 8.8/2.2

x = 4

To know how fast the kickers are going will be

4.7x = 4.7 × 4 = 18.8 miles

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x)  = 2(3x)² - 1

f(3x)  = 2*9x² - 1

f(3x)  = 18x² - 1

f(g(x)) =  18x² - 1

Substitute x  = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

wait holy gosh dude is this about the congruence stuff? I think I can help!

ok so triangle RST is very similar to triangle ABC BECAUSE triangle RST is just dialated and or turned around it also has the lines so it must be similar or closest to 1.5 for each sides

srry if this is wrong if it is plz correct me nicely in the comments lol

I took the quiz on k12 sooo

Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]

x= [tex]\frac{-2}{5}y-2[/tex]

2-  3x+y+−y=66+−y

3x=−y+66

[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]

[tex]x=\frac{-1}{3}y+22[/tex]

Answer: 3

Step-by-step explanation:

A florist sold 12 flower bouqets yesterday, which included 2 daisy bouquets. This shows that the fraction of daisy bouquet is 2/12 = 1/6.

Therefore, if there are 18 boquetes sold, the number that's expected to be daisy bouquets will be:

= 1/6 × 18

= 3

Answer:

135.71 sea otters

Step-by-step explanation:

y = 70(1.18)^4

y = 70 x 1.9387

y = 135.71

The number of sea otters after 4 years with an exponential growth of 18% will be 135.71.

A connection of the form y = ax, where x is an independent variable that spans the entire real number line and is written as the exponent of a positive number, is known as an exponential function in mathematics.

The exponential growth function is given as,

y = C x^n

y = 70(1.18)⁴

y = 70 × 1.9387

y = 135.71

Hence "After 4 years, there will be 135.71 sea otters, representing an exponential growth of 18%".

Answer:

why

Step-by-step explanation:

Answer:

y = -0.5x + 3

Step-by-step explanation:

The equation of a linear model is generally represented as;

y = mx + b

where m

is slope and b is the y-intercept

We can get slope by using the slope equation

m =

(y2-y1)/(x2-x1)

(x1,y1) = (-4,5)

(x2,y2) = (4,1)

m = (1-5)/(4 + 4) = -4/8 = -0.5

The equation is thus;

y = -0.5x + b

to get b, we substitute any of the two points coordinates

1 = -0.5(4) + c

1 = -2 + c

c = 2 + 1

c = 3

The formula to find area is L x W x H

Length x Width x Height

So 9 ft x 7 ft x 26 ft = 1638 ft

Answer:

B

Step-by-step explanation:

Reflect x-axis means (x,y) becomes (x, -y)

Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x

Up 4 units means f(x) = x becomes f(x)= x + 4

So lets put that together

[tex]f(x) = \sqrt{x}[/tex]

[tex]f(x) = -\sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]
