(36)^-2 x (9)^-2 i need help

Answers

Answer: 1/104976

Step-by-step explanation:

You can get rid of negative exponents by flipping the number. So in this case,  the expression would change to: 1/(36)^2 x (9)^2.

From there, simplify the expression. 36 squared is 1296. 9 squared is 81. Multiply those together to get 104,976.

A tree that is 30 tall casts a 40 shadow. What is the distance from the top of the tree to the end of the shadow?

Answers

The distance from the top of the tree of height 30 tall to the end of the shadow is 50.

What is distance?

Distance is the length between two point.

To calculate the distance from the top of the tree to the end of the shadow, we use the formula below.

Note: The tree and the shadow form a right angle.

Formula:

a = √(b²+c²)................. Equation 1

Where:

a = Distance of from the top of the tree to the end of the shadowb = Height of the treec = Length of the shadow

From the question,

Given:

b = 30 c  = 40

Susbtitute these values into equation 1

a = √(30²+40²)a = √(900+1600)a = √2500a = 50

Hence, the distance from the top of the tree to the end of the shadow is 50.

the graph of linear f passes through the point 1 -9 and has a slope of -3 what is the zero of f
(A) 2
(B) 4
(C) -6
(D) -2

Answers

Answer:

(C) -6

Step-by-step explanation:

Given the following data;

Points on the graph (x1, y1) = (1, -9).

Mathematically, the equation of a straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

To find the zero of the linear function f, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - (-9) = -3(x - 1)

y + 9 = -3x + 3

y = -3x + 3 - 9

y = -3x -6 = mx + c

Intercept (c) or zero of a function = -6

Write an equation that represents a discount of 18% on a retail price of $55. Let p represent the new price. f

Answers

An equation that represents a discount of 18% on a retail price of $55 can be written as follows:

p = 0.82 * 55

In this equation, p represents the new price after the discount has been applied, and 0.82 represents the percentage of the original price that remains after the discount has been applied (100% - 18% = 82%).

Solving this equation, we find that the new price, p, is equal to $45.90.

Note: This equation represents a discount, which means that the final price, p, will be less than the original price. If you want to represent a markdown (i.e., a price increase), you would use a value greater than 1 for the percentage factor (e.g., 1.18 for a markdown of 18%).
The equation here is 0.88

On solving the provided question we cans ay that - here in linear equation, y = 3 and x = -1/2

What is a linear equation?

The algebraic equation y=mx+b is known as a linear equation. B is the y-intercept, and m is the slope. The previous sentence, where y and x are variables, is commonly referred to as a "linear equation in two variables." Bivariate linear equations are those that contain two variables in them. The linear equations 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples. When an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is referred to as being linear.

y = 2x + 1 - linear equation.

value of y;

[tex]x = 0\\y = 2(0) + 1\\y = 2 + 1\\y = 3[/tex]

Two tourists start walking across the Golden Gate Bridge at the same time but from opposite
ends. One of the tourists is walking at a leisurely rate of 0.9 meters per second, and the other
is walking at a rate of 1.1 meters per second. Given that the bridge is 2,738 meters in length,
how long will it take for the tourists to meet?
minutes and
seconds

Answers

Answer:

The tourists will meet at the midpoint of the bridge, which is 2738/2 = 1369 meters from each end.

At their respective walking speeds, it will take the first tourist 1369/0.9 = 1521.67 seconds to reach the midpoint, and it will take the second tourist 1369/1.1 = 1242.73 seconds.

Therefore, it will take them a total of 1521.67 + 1242.73 = 2764.4 seconds to meet.

Since there are 60 seconds in a minute, the time in minutes is 2764.4 / 60 = 46.07 minutes.

Therefore, it will take the tourists 46 minutes and 0.4 seconds to meet.
