A man standing 24 feet from a building observes the angle of elevation of its top to be 38°. Find the height of the building to the nearest tenth.

Answer: t>6

Step-by-step explanation:

Amount to pay = Cost of kennel + (Cost per toy )x (Number of toys)

Let t = the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.​

Given, At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy.

Amount to pay =  $(50.75 + 3.75t)

At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy.

Amount to pay =  $(43.25 + 5t)

According to the question , we have

50.75 + 3.75t < 43.25 + 5t

Subtract 3.75t from both sides

50.75+ 3.75t -3.75t   < 43.25 + 5t -3.75t

⇒ 50.75< 43.25 +1.25 t

Subtract  43.25 from both sides, we get

50.75 - 43.25 < 1.25 t

⇒  7.5< 1.25 t

Divide both sides by 1.25 we get

⇒   6<t

Hence, the required inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option:

Step-by-step explanation:

[tex]20 + (y - 10) + 4y \\20 + y -10 + 4y \\20 - 10 + y + 4y \\10 + 5y[/tex]

The simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The linear expression is:

= 20 + (y - 10) + 4y

As we know, the linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

After simplifcation:

Adding like terms:

= 5y + 10

Thus, the simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.

Answer:

The answer would be C

Step-by-step explanation:

778 is greater than 750, therefore the estimate for that would be 800. Then for 23, it is less 25 therefore, 23 would estimate to 20

Answer:

Step-by-step explanation:

Here, "co" means "shared."  Two lines are coplanar if both lie in the same plane (in which case there are three possibilities:  the lines intersect in one point, the lines coincide (are one and the same), or the lines never intersect (in which case we call them "parallel."

Suppose we take a look at a three-dimensional space with perpendicular x-, y- and z-axes.  If we let one of these three variables be a constant, then the resulting area is a plane (with two-dimenions).  if we held z constant, then the plane would be the xy plane, and any two lines lying entirely in this plane are deemed to be "coplanar:"  they lie in the same plane.

Answer and Step-by-step explanation:

F(x) = x^3 (a)

then

compute f(x) dx for each of these, compute the corresponding absolute error.

Solution:  f(x) = x3

            F(x) d(x) = 3x2

The absolute error are ∆x= |x-ẋ|, ∆f=|f(x) – f(ẋ)|

(b) Compute the approximation L, and T, for n=4, 8, and 16 for an integral part.

The linear (L) approximation of function f(x) = x3, n= 4

  f(4) = (4)3 = 64 and f”(4) = 3(4)2 = 48

The linear approximation is  L4(x) = f (4) + f’(4)(x-4)

                           = 64 + 48 (x-4)

For n= 8,

  f(8) = 512 and f,(8)= 3(8)2= 192

The linear approximate is L8(x) = f(8) + f’(8)(x-8)

Similarly for n= 16 the linear approximate is L16(x) = f (16) + f (16) (x-16)

The approximation for T, trapezoidal rule is:

a ʃb f(x)dx = Tn

for n = 4 the T approximation is:

T4  =a ʃb  x3 dx

For n= 8 :

T8 = a ʃb x3 dx

For n= 16 : T16= a ʃb x3 dx.

Estimate one digit past the smallest precisely known digit or marking

Step-by-step explanation:

To determine the last digit in any measured number : Estimate one digit past the smallest precisely known digit or marking

This is employed mostly when trying to round off a measured or calculated number to a precise number of digits and in other to determine the last digit in the given number we will have to estimate one digit past the smallest precisely known digit

The true statement about how to determine the last digit in any measured number is (b) Estimate one digit past the smallest precisely known digit or marking

A measured number is a number derived from taking measurements (take for instance weight, length, distance etc.)

The number that ends the measured number (i.e. the last digit) is always an estimated digit.

This means that, we have to count one digit past the supposed last digit and then estimate (i.e. approximate)

Hence, the true option is (b)

Answer:

its the last one y = -1/3x + 3

Answer:

y= - 1/3x + 3

Step-by-step explanation:

Use 2 points and plug them into the slope formula

(0,3)(3,2)

Slope =(y2−y1)/(x2−x1)

                 (2−3)/(3−0)

                      −1/3

Slope is negative 1/3

Now look on the graph where the line goes through 0,3

This is the y intercept

so your final answer is y= - 1/3x + 3

Answer:

Probability of choosing number = 0.9192

Step-by-step explanation:

Given:

New mean = 87.8

Mean = 85

Standard deviation = 14

Number picked = 49

Find:

Probability of choosing number

Computation:

Probability of choosing number = [New mean - Mean] / [Standard deviation / √Number picked]

Probability of choosing number <= [(87.8-85)]/[(14/7)]

Probability of choosing number = 0.9192

Answer:

x=3

Step-by-step explanation:

1) 10x+1-1 = 12x-5-1, this becomes a new equation

Equation: 10x = 12x-6

2) 10x-12x = 12x-12x-6, this become a new equation

Equation: -2x = -6

3) Divide both sides by -2: -2x/2 = -6/2

4) Once you simplify, you will get x=3

Answer: D. f(-2)=g(-2)

Step-by-step explanation:

This problem is asking which of the options are correct. Looking at the options, you can see that it is saying that the same x-coordinate on f(x) and g(x) gives you the same solution. Therefore, we want to find the solution of the graph.

Looking at the graph, we can see that the solution is (-2,4). We know this because that is the intersection point of f(x) and g(x). Therefore, D is the correct answer.

Answer: x=5/3

Step-by-step explanation:

For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.

5x+5=2x+10

The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".

5x+5=2x+10                     [subtract both sides by 2x]

3x+5=10                           [subtract both sides by 5]

3x=5                                [divide both sides by 3]

x=5/3

Now, we have found the unknown number, x=5/3.

Step-by-step explanation:

f(x) = 38 cos(x²)

Use chain rule to take the derivative.

f'(x) = -38 sin(x²) (2x)

f'(x) = -76x sin(x²)

Use product rule and chain rule to take the derivative.

f"(x) = -76x cos(x²) (2x) + (-76) sin(x²)

Answer:

Adding integers means adding integers with the same signs, while subtracting integers means adding the integers of opposite signs.

Step-by-step explanation:

Answer:

  addition is subtraction of the opposite, and vice versa

Step-by-step explanation:

Subtracting an integer is the same as adding its opposite. Likewise, adding an integer is the same as subtracting its opposite.

  4 - 3 = 4 + (-3) = 1

  4 + (-3) = 4 - 3 = 1

Or, ...

  4 - (-3) = 4 + 3 = 7
