The nth term of a sequence is n^2 + 5.

Find the first three terms and show that 261 is a term in this sequence.

Answer:

64 cm^2

Step-by-step explanation:

First we find the area of the central square: 4^2=16 cm^2

Then we can find the area of the 4 other triangles: 6*4*1/2*(4)->(There are 4 triangles)

We get 48+16, which is 64 cm^2

Answer=

$10.75 is the cost of an adult ticket

Answer:

£10.75

Step-by-step explanation:

6 tickets=£40.50

cost of adult=£6 more than a child's

let's form an equation!

x is the cost of children tickets and since we have 4 of them it leaves us with 4x. And an adult ticket is £6 more than a child's, so that leaves us with 6+x. And since we have 2 of them we get 2(6+x). So with this info, we can make an equation and solve it to find x:

2(6+x)+4x=40.50

12+2x+4x=40.50

12+6x=40.50

6x=28.50

x=4.75=the cost of a child ticket

adult ticket =£10.75

Answer:

If the exponent was 1, the function would remain constant but if the function was between 0-1 it would decrease towards the x-axis.

Answer:

x=-2

Step-by-step explanation:

6(x+1)=-2(3x+9)

Distribute the 6.

6x+6=-2(3x+9)

Distribute the -2.

6x+6=-6x-18

Move the variable to the left-hand side and change the sign.

6x+6+6x=-18

Collect like terms

12x=-18-6

Calculate the difference.

12x=-24

Divide both sides by 12.

x=-2

Answer:

its 19 ur welcome byeeee

Step-by-step explanation:

Answer:  3 seconds

Step-by-step explanation:

h(t) = -16(t)^2 + 112(t)

Set h(t) = 192 feet

192 = -16(t)^2 + 112(t)

0 = -16(t)^2 + 112(t) - 192

Solve using the quadratic formula:  There are two solutions, 3 and 4 seconds.  Three seconds is the first time it reachers 192 feet,  At four seonds it's on its way down.

The function can also be graphed (attached).

Answer:

The length of the plane is 333 in.

Step-by-step explanation:

Plane length = (1.85)(Boat length)      

The 0.85 in (1.85) above represents the added length; the (1.85) represents the length of the boat PLUS 0.85 time the length of the boat.

Plane length is (1.85)(Boat length) = 1.85(180 in) = 333 in

The length of the plane is 333 in.

Answer:

There are 12 boys and 36 girls.

Step-by-step explanation:

This equation should help explain it.

x + 3x = 48

Let's say that there are an x number of boys. Then there would be 3 times x of girls. So x (the boys) plus 3x (the girls) equal 48 (the total amount of students).

To solve this equation, first add x and 3x to get 4x. Then divide that by 48, and we get x = 2.

The amount of boys = x, so there are 12 boys.

The amount of girls = 3x, so there are 3 times 12, or 36 girls.

Hello mariamhifzur!

Given,

A rectangle is 40 cm long & 30 cm wide. So,

Now, using a scale of 1 cm to represent 10 cm we need to draw a scale diagram of the rectangle on the grid.​

At first we need to convert the measurements of the rectangle in real life to its scale measurements.  In the question given, we need to convert 10 cm to 1 cm in the scale. So,

Now, suppose each grid is equal to 1 cm. Then, we can take the measurements as :

Let's draw the figure now. Our rectangle looks like ... (see the attachment).

You didn't really describe what we're supposed to do, but I'm going to assume they want you to graph it.

The first equation has a slope of 3/5x, meaning that for every 3 units it moves upwards, it moves right 5 units. It has a y-intercept of 8, meaning that the line will cross through (0, 8) on the coordinate plane. Start your point on (0, 8) and draw a line that goes up 3 units and 5 units.

The second equation has a slope of -4/5x, meaning that for every 4 units it moves upwards, it moves left 5 units OR for every 4 units it moves down it moves 5 units right. The y-intercept is 1, so the line will go through (0, 1). Start your point on (0, 1), and draw a line that follows the slope, just like last time.

If this is all correct and the best answer, please give me brainliest as I'm trying to rank up. Thanks!

A catfish with a length of 33 inches would weigh 30 pounds.

A linear equation is in the form of:

y = mx + b

where y,x are variables, m is the rate of change and b is the y intercept.

Let y represent the catfish weight with x inches length

From the line of best, it passes through (20, 4) and (23, 10), hence:

y - 4 = [(10 - 4)/(23 - 20)](x - 20)

y = 2x - 36

For a length of 33 inches:

y = 2(33) - 36 = 30 pounds

A catfish with a length of 33 inches would weigh 30 pounds.

Answer:

y = -5 + 2

Step-by-step explanation:

    We can use change in y over change in x to find slope:

[tex]\frac{y2-y1}{x2-x1} =\frac{-8--3}{2-1} =\frac{-8+3}{1} =-5[/tex]

So, our slope (aka m) is -5.

    For our b, or the y-intercept, we will need to find what value y is when x is 0. To do this, we will plug in a point for what we have so far, and then solve for b

y = -5x + b

-8 = -5(2) + b

-8 = -10 + b

2 = b

    And there is our equation,

y = -5 + 2

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y + 4 = [tex]\frac{1}{3}[/tex] (x - 1) ← is in point- slope form

with m = [tex]\frac{1}{3}[/tex] and (a, b ) = (1, - 4 ) → B
