Hey there, hope you are having a nice day! :)

5 less than 25 simply means we subtract 5 from 25.

Now, let's write it as a numerical expression (let's express it in numbers)

Answer:

k=37

Step-by-step explanation:

If we plug in 2 for t, which it tells us is the input, then the output of the problem will be 37

k=13t-2

Plug in the value for t.

k=13(2)-2

k=39-2

k=37

The half-life of the element is 13 minutes, which means after 13 minutes, any starting amount decays to half. So element X decays with a rate k such that

[tex]\dfrac12 = e^{13k}[/tex]

Solve for k :

[tex]\ln\left(\dfrac12\right) = \ln\left(e^{13k}\right)[/tex]

[tex]-\ln(2) = 13k \ln(e)[/tex]

[tex]-\ln(2) = 13k[/tex]

[tex]\implies k = -\dfrac{\ln(2)}{13}[/tex]

Now, we solve for t such that

[tex]36 = 710e^{kt}[/tex]

[tex]e^{kt} = \dfrac{18}{355}[/tex]

[tex]\ln\left(e^{kt}\right) = \ln\left(\dfrac{18}{355}\right)[/tex]

[tex]kt = \ln\left(\dfrac{18}{355}\right)[/tex]

[tex]-\dfrac{\ln(2)}{13} t = \ln\left(\dfrac{18}{355}\right)[/tex]

[tex]\implies t = -\dfrac{13 \ln\left(\frac{18}{355}\right)}{\ln(2)}[/tex]

[tex]\implies t = -13 \log_2\left(\dfrac{18}{355}\right) \approx \boxed{55.9}[/tex]

The value of the missing angle is [tex]34.1^{o}[/tex]. Option C.

Trigonometric functions are a set of functions which can be used to determine the value of an unknown side or angle of a given right triangle.

To determine the missing angles, we have;

sin x = opposite/ hypotenuse

        = 14/ 25

sin x = 0.56

x = sin^-1 0.56

Answer:

Your answer is 114.

Step-by-step explanation:

Since theres 342, and 6 pounds try to see what each pound equals first. Try to divide 342 in half, which gets you 171 one third of 171 is 57. So your answer is 57. To check your answer 57 x 3 would get 171. 171 x 2 would get you 342 so your answer is 57 + 57 = 114

Answer:

Domain: [tex][-2,1)[/tex]

Range: [tex][0,4][/tex]

Step-by-step explanation:

Domain

We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write [tex][-2,1)[/tex]. Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.

Range

Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be [tex][0,4][/tex].

Answer:

[tex]y=\frac{6}{5}x+3[/tex]   and    [tex]y=-\frac{2}{5} x-5[/tex]

Step-by-step explanation:

To find the slope (gradient) of a line, choose 2 points on the line and put their coordinates into the formula:  [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the 2 points.

The y-intercept is the y-coordinate of the point where the line crosses the y-axis.

The question has given you one point that both lines pass through: (-5, -3)

You also need to determine the points where both lines cross the y-axis to determine their y-intercepts - use those as the second points.

From inspection, for the upper line this is (0, 3) and for the other line this is (0, -5)

Therefore, the slope of the upper line is: [tex]m=\frac{3--3}{0--5}=\frac{3+3}{0+5} =\frac{6}{5}[/tex]

This line crosses the y-axis (0, 3) so its y-intercept is 3

Therefore, the equation is [tex]y=\frac{6}{5}x+3[/tex]

The slope of the lower line is: [tex]m=\frac{-5--3}{0--5}=\frac{-5+3}{0+5} =\frac{-2}{5}[/tex]

This line crosses the y-axis (0, -5) so its y-intercept is -5

Therefore, the equation is [tex]y=-\frac{2}{5} x-5[/tex]

3. Finally, the answer is:

Step-by-step explanation:

radius of a circle=7.5 cm

now,

circumference of a circle=2[tex]\pi[/tex]r

                                          =2*3.14*7.5

                                          =47.1 cm

6) 65 * 7200 /100 = 4680 $

7) OP=price/ (1− Discount percentage)

original price = 32.89 / (1- 0.85)

= 219.26 $

8)Let the total people in crew is x of which 8(66.2/3%) are men.

x *(66.2/3/ 100 ) =8 or

(x⋅200/3 )*(1 /100)=8 or

x=3 * (8/2)=12

there are 12 people in the crew

9) 12,800 * 15 /100 = 1920$ taken as taxes

Solve for c :

x⁴ + cx² + 100 = 0

cx² = -(x⁴ + 100)

c = - (x⁴ + 100)/x²

If x = 0, the right side is undefined and c would have no solution.

Answer:

Step-by-step explanation:

Answer:

6.25 Years

Step-by-step explanation:

First, find 8% of 40,000 which is 3,200 which represents how much the initial amount increases per year.

Next, find out how much you need to increase by subtracting 40,000 from 60,000 which means you need 20,000 more dollars.

Next, divide how much money you need by how much it increases to see how many years it will take.

20,000 divided by 3,200 is 6.25

Answer:

Option C.

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

            = x² + [-(i)²√(13)²]  [Since i = √(-1)]

            = x² - (i√13)²

            = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]

Option C will be the answer.

Answer:  D) Van: 8, Bus: 25

Bus can carry 25 students ,  van can carry 8 students.

Explanation:

Let vans be v and buses be b

Equations:

6v + 2b = 98 ..........from Theory 1

10v + 2b = 130 ..........from Theory 2

Making b the subject:

6v + 2b = 98

b = (98 - 6v)/2 ............. equation 1

10v + 2b = 130

b = (130 - 10v)/2  .........equation 2

Solving them simultaneously:

(130 - 10v)/2 = (98 - 6v)/2

130 - 10v = 98 - 6v

-6v + 10v = 130 - 98

4v = 32

v = 8

Therefore each van can carry 8 students.

Then the bus can carry: (98 - 6v)/2

                                    → (98 - 6(8))/2

                                    →  25 people
