According to the model, Leo's initial deposit was $0

The model is given as

a = 18t + 5

When he makes his initial deposit, the value of t is

t = 0

i.e. this represents his balance before he starts saving on a weekly basis

Substitute 0 for t in the equation a = 18t + 5

So, we have

a = 18 * 0 + 5

Evaluate

a = 5

Hence, Leo's initial deposit was $0

So, For this purpose, we know that the

Speed is the time rate at which an object is moving along a path

From the given information:

A cyclist his bike at a speed of 40 kilometers per hour

Then

The distance he covered in 5 hours = 40*5

The distance he covered in 5 hours = 200.

And then

The speed in miles :

We have given that the  1 mile is equal to 1.6 kilometers

Then

If he covers a 40 kilometers in a hour then

in miles it becomes = 40/1.6

In other words,

Speed in miles = 40/1.6

Speed in miles = 25 miles per hour.

The height of the ball according to the function h(t) is 16 feet after 1.92 seconds and after 0.46 seconds.

A function is defined as a expression containing one or more variables.

Technically speaking, a function is a means of linking a set of inputs to a set of outputs.

The height of the ball  at any time t is given by the function:

[tex]h(t)=-16t^2+38t+2[/tex]

Now the required height of the ball(in feet) is 16 feet. We have to find the value of t for which h(t)=16.

Let us substitute the values:

[tex]\implies h(t)=-16t^2+38t+2\\\implies 16=-16t^2+38t+2\\\implies 16t^2-38t+14=0\\\implies 8t^2-19t+7=0[/tex]

This is in the form of a quadratic equation in t.

Solving by using the quadratic formula:

We know that for a quadratic equation [tex]ax^2+bx+c=0[/tex]

[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Therefore for the above quadratic equation:

[tex]t=\frac{-(-19)\pm \sqrt{(-19)^2-4(8)(7)}}{2(8)}\\t=\frac{19+\sqrt{137}}{8},t=\frac{19-\sqrt{137}}{8}\\t=1.919...,t=0.455...[/tex]

Therefore the ball reaches the height of 16 feet at times 1.92 seconds and at 0.46 seconds.

Y=2x-1

Step-by-step explanation:

(0,-1) parallel to y=2x + 4

parallel means the slope is the same (i.e m=2)

general equation would be

y=2x+k

now (0,-1) belongs to line where x=0 and y= -1

-1 =2(0)+k

-1 = k

hence k is -1

Considering the definition of perpendicular line, you obtain:

1) the equation of perpendicular line is y= -5x + 7.

2) the equation of perpendicular line is y= 7x + 54.

A linear equation o line can be expressed in the form y = mx + b

where

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of  1/5. So:

1/5× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (1/5)

slope perpendicular line= -5

So, the perpendicular line has a form of: y= -5x + b

The line passes through the point (2,-3). Replacing in the expression for perpendicular line:

-3= -5× (2) + b

-3= -10 + b

-3 +10 = b

7= b

Finally, the equation of perpendicular line is y= -5x + 7.

In this case, the line is x +7y -12= 0. Expressed in the form y = mx + b, you get:

7y= -x +12

y= (-x + 12)÷ 7

y= -1/7x +12/7

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of  -1/7. So:

-1/7× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (-1/7)

slope perpendicular line= 7

So, the perpendicular line has a form of: y= 7x + b

The line passes through the point (5,-9). Replacing in the expression for perpendicular line:

-9= 7× (-9) + b

-9= -63 + b

-9 + 63 = b

54= b

Finally, the equation of perpendicular line is y= 7x + 54.

In summary, you obtain:

1) the equation of perpendicular line is y= -5x + 7.

2) the equation of perpendicular line is y= 7x + 54.

Step-by-step explanation:

(e)

because BCDF is a parallelogram, it means that F D = B C = 4.

and F B = D C = 6.

because EDCF is a parallelogram, it means that D C = E F = 6.

that means that E F = F B = 6, so the diagonal E B of ABDE is intersected by the other diagonal A D in the middle at F.

because ABCF is a parallelogram, it means that A F = B C = 4.

that means that A F = F D = 4, so, also the diagonal A D of ABDE is intersected by the other diagonal E B in the middle at F.

when 2 line segments E B and A D intersect each other that way, that makes them the diagonals of a parallelogram.

therefore, ABDE is a parallelogram.

Answer: 6.83

Step-by-step explanation: 34.18 - 6.86 = 27.32 /4 = 6.83

Step-by-step explanation:

ok, let's try this again. we need to explain congruence then in its details as an implicit part of the proof, as everything boils down to that.

due to AE = FC we also know that ED = BF.

because as ABCD is a parallelogram, it means AD = BC (and AB = DC).

and AD || BC, AB || DC.

as AD = AE + ED and BC = BF + FC, it means that

AE + ED = BF + FC

with AE = FC we can then simplify to

ED = BF.

as AD || BC, so is also ED || BF.

since the distance from E to D is the same as for B to F, it means that EB and DF must be equidistant to each other, and that means they are parallel.

and because ED || BF, that also means that both line segments are equidistant from each other, and that means that the connections between their end points (EB and DF) must have the same lengths.

therefore, the shape is a quadrilateral with 2 pairs of parallel and equally long line segments. and that is the definition of a parallelogram.

so, BEDF is a parallelogram.

The real number whose sum and product are both 12 area 1.101 and 11.899

Let first number be  " x "

Let other number be " 12 - x "

According to the question the product of two numbers is 12 which is given by         x(12 - x) = 12

                        12x - x² = 12

                         x²- 12x + 12 = 0

Using quadratic formula , we get

Put a = 1 , b = -12 , c = 12 in equation (1) , we get

                      [tex]\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(12)} }{2(1)} \\\\\frac{12\pm\sqrt{144-48} }{2} \\\\\frac{12\pm\sqrt{96} }{2} \\\\\frac{12\pm9.79 }{2} \\\\[/tex]

Answer:

n = 7

Step-by-step explanation:

You will want to add all common factors with each other.

So that would be n + 3n + 5n which would be 9n.

Then -8 + 1 would be -7. So now it should be 9n - 7.

You are going to set 56 equal to 9n - 7, so that would be 9n - 7 = 56.

After that, you will have to leave 9n alone by itself, so you would have to add 7 to both sides. Your final equation should be 9n = 63.

After that, you should divide both sides by 9 since you want n alone.

So 63 ÷ 9 would be 7. So at the end, n = 7.

Answer:

-7

Step-by-step explanation:

To add a positive number, 5, and a negative number, -12, take the absolute value of both numbers.

You get 5 and 12.

Subtract the smaller absolute value from the larger absolute value.

12 - 5 = 7

The sign of the answer is the same sign as the number that has the larger absolute value. The absolute of 5 is 5. The absolute value of -12 is 12. -12 has the larger absolute value, and -12 is negative, so the answer is negative.

5 + (-12) = -7

Step-by-step explanation:

you mean the slope of the line between (8, 9) and (23, 9).

we can see that right away, as the y value does not change. it means it is a flat line, and that means the slope is 0.

now, formally :

the slope of a line is (y coordinate change / x coordinate change) when going from one point on the line to another.

the direction does not matter, but once we pick one for the comparison of one coordinate, we have to use the same direction also for the other.

I prefer to go from left to right.

so, from (8, 9) to (23, 9).

x changes by +15 (from 8 to 23).

y changes by 0 (from 9 to 9).

the slope is therefore 0/+15 = 0.
