A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?

The balance after 9 years is $1139.94 rounded to the nearest cent.

The formula to use in this case is A = P(1 + r)^nt, where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years.

Given the information in the problem, we know that:

P = $800.00 (the principal or starting amount)

r = 0.04 (the interest rate as a decimal)

n = 1 (the interest is compounded annually)

t = 9 (the number of years)

Plugging these values into the formula, we get:

A = $800.00(1 + 0.04)^9

To solve for A, we need to calculate (1 + 0.04)^9

=1.04^9

=1.041.041.041.041.041.041.041.041.04

=1.424928

A = $800.00*1.424928

A = $1139.94

So the balance after 9 years is $1139.94 rounded to the nearest cent.

Therefore, The balance after 9 years is $1139.94 rounded to the nearest cent.

Using the given information, we can calculate the z-score as z = (56.4 - 67.6) / 3.5, which gives us a z-score of -2.3. This means that 2.3 standard deviations below the mean of adult men's heights is the doorway height of 56.4 inches. Since the area under the normal curve from -∞ to -2.3 is 16%, this means that 84% of adult men can fit through the door without bending.

Using the given information and the desired percentage, we can calculate the z-score as z = (x - 67.6) / 3.5, where x is the doorway height. Solving for x, we get x = 57.6 inches. Therefore, a doorway height of 57.6 inches would allow 40% of adult men to fit through without bending.

Step-by-step explanation:

The difference between the largest 8-digit number and the smallest 7-digit number is 98999999.

The aim is to find the smallest 7-digit and largest 8-digit numbers, and then we need to determine the difference between these two values.

Let's start by finding the smallest 7-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 therefore it  can be used in the highest place value.

Thus, we can create the required 7-digit smallest number with 0 and 1.

Hence, the smallest 7-digit number is 1000000.

Now, we will discover the largest 8-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 8-digit number with the digit 9.

Thus, the largest 8-digit number is 99999999.

Now, find the difference between these two values.

So, we can determine the difference between the smallest 7-digit and the largest 8-digit numbers by subtracting the smallest from the largest.

Thus, we get,

⇒99999999−1000000

⇒98999999

Hence, 98999999 is the difference between the smallest 7-digit and the largest 8-digit numbers.

The length of BD and CD are 15 units and 20 units respectively

By the Angle Bisector Theorem, we have:

BD/DC = AC/BC = 21/28

We can use the Pythagorean Theorem to find AC:

AC² + BC² = AB²

21² + 28² = AB²

AB = 35 units

Now we can use the Angle Bisector Theorem to find BD:

BD/DC = 21/28

BD + DC = AB

BD = (21/49) × AB

BD = (21/49) × 35

BD = 15 units

To find CD, we can use the fact that BD + DC = AB:

CD = AB - BD

CD = 35 - 15

CD = 20 units

Therefore, the length are BD = 15 and CD = 20 units.

The perimeter of the pentagon is 76 units. The solution is obtained using tangent to circle.

What is tangent to a circle?

A line that touches a circle only once is said to be tangent to it. A point to circle can only have one tangent.

In the figure, the circle is circumscribed by the pentagon.

We are given QZ = 10, YX = 9, WX = 9, UW = 17, and US = 10

VW = WX = 9   (tangent of circle)

So, VU = UW - VW

VU = 17-9= 8

Since, VU and UT are tangents of circle, therefore

UT = 8

US = UT + TS

⇒10 = 8 + TS

⇒TS = 2

Now, TS and SR being tangents, therefore

TS = SR = 2

Also, RQ and QZ are tangents, therefore

RQ = QZ = 10

Similarly, ZY and YX are tangents, therefore

ZY = YX= 9

Thus, Perimeter = SQ + QY + YW + WU + US

⇒Perimeter = SR+ RQ+ QZ+ ZY+ YX+ XW+ UW+ US

⇒Perimeter = 2+ 10+ 10+ 9+ 9+ 9+ 17+ 10

⇒Perimeter = 76 units

Hence, the perimeter of the pentagon is 76 units.

The value for a in quadratic function a(x-1)²+3 is obtained as a = 2.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The vertex of the quadratic function is (1,3).

The line passes through the points (3,5).

The equation is in the form - a(x-1)²+3

It is known that the vertex form of a quadratic function is f(x) = a(x-h)² + k, where (h,k) is the vertex of the parabola.

So it can be written -

f(x) = a(x-1)² + 3

Substitute the value of (1,3).

f(1) = a(1-1)² + 3 = 3

And for the point (3,5) the equation will be -

f(3) = a(3-1)² + 3 = 5

Set up a system of equations -

a(1-1)² + 3 = 3

a(3-1)² + 3 = 5

Solving for a in these equations -

a = 2

So, the value of k that makes the system of equations kx - 5y = 2, 6x + 2y = 7 has no solution is -1.

A system of linear equations has no solution when the equations are inconsistent, which means that there is no set of values for the variables that would make both equations true at the same time.

In the case of the system of equations kx - 5y = 2, 6x + 2y = 7, we can check for consistency by trying to find a unique solution for the system. We can use different methods such as elimination, substitution or Gaussian elimination.

If we use elimination method, we try to eliminate one of the variable from one equation and substitute it in another equation. By adding the two equations, we get: (k + 6)x = 9, which implies that the value of x is x = 9/(k+6).

Now by substituting this value into the first equation we get k*9/(k+6) - 5y = 2

And we can find the value of y by dividing both sides by -5/1: y = (2*(k+6))/(5*k)

Now if we substitute this value of x and y into the second equation:

6x + 2y = 7

We get: 6*(9/(k+6)) + 2*((2*(k+6))/(5*k)) = 7

And if we simplify this equation we get: 9 + 4/(5*k) = 7(k+6)/(k+6)

And that gives us k = -1, which means the system has no solution.

Therefore, the value of k that makes the system of equations kx - 5y = 2, 6x + 2y = 7 has no solution is -1.

a₁x + b₁y + c₁ = 0

and

a₂x + b₂y + c₂ = 0

we don't have to make any changes to them

According to the law, an equation has infinitely many solutions if

The four conditions of a binomial distribution are: independence, normality, symmetry, and rarity.

Independence: Each trial in a binomial distribution is independent of the other trials, meaning that the outcome of one trial does not affect the outcome of any other trial.

Normality: The distribution of the data follows a normal distribution, meaning that it is bell-shaped and symmetrical.

Symmetry: The binomial distribution is symmetrical around the mean, meaning that the probability of the outcome being above the mean is the same as the probability of the outcome being below the mean.

Rarity: The binomial distribution is characterized by rare events, meaning that the probability of an event occurring is relatively low. This is because the outcomes of each trial are determined by a random process.

The equation states the ratio of two numbers, where the numerator and denominator can be changed to obtain an equivalent equation. To solve for the meaning term, the numbers in the numerator and denominator must be manipulated to get the same ratio. To do this, the numerator and denominator of the first equation can be multiplied or divided by the same number to get the same ratio as the second equation. When the ratio is the same, the meaning term can be found by dividing the numerator of the second equation by the denominator of the first equation. For example, the equation 2:3 = N:21 can be solved by multiplying 3 and 21 by 2, giving 6:42 = N:42, which has the same ratio. The meaning term is then found by dividing 42 by 3, giving N = 14.
