Answer 1               8      

Step-by-step explanation:

[tex]y = \frac{1}{2} e^{x}[/tex]  equation is represented by the given graph.

What is graph?

"Graph is defined as the representation of relation between two variables on the coordinate plane."

According to the question,

From the observation of the graph,

for x= 0

y- intercept = [tex]\frac{1}{2}[/tex]

a.  [tex]y = \frac{1}{8} e^{x}[/tex]

Substitute x = 0 in the equation we get,

[tex]y = \frac{1}{8} e^{0}[/tex]  

⇒ [tex]y = \frac{1}{8}[/tex]

Therefore,

Option (a) is not the correct answer.

b. [tex]y = \frac{1}{2} e^{x}[/tex]

Substitute x = 0  in the equation we get,

[tex]y = \frac{1}{2} e^{0}[/tex]  

⇒ [tex]y = \frac{1}{2}[/tex]

which is same as graph value.

Hence, Option (b) is  the correct answer.

One day 197 Eagle Ridge students went on a field trip. Five busses were filled with the same number of students, and two students traveled separately by car. How many students were on each bus?

Answers

Answer: 39 students

Step-by-step explanation:

First, remove the number of students who traveled by car from the total number so we can see the number of students who traveled by bus:

= 197 - 2

= 195 students by bus.

These 195 students traveled in 5 buses. The number of students on each bus is therefore:

= No. of students traveling by bus / No. of buses

= 195 / 5

= 39 students

(259 inches

Answers

Answer:

14.42inches

Step-by-step explanation:

Given the following

b = 5 in

c = 8in

we are to find the measure of the space diagonal line

Using the pythagoras theoreml

l^2 = b^2 + c^2

l^2 = 13^2 - 5^2

l^2 = 169 -25

l^2 = 144

l = 12in

To get the measure of the space diagonal line in the box, we will use the pythagoras theorem;

s^2 = l^2 + c^2

s^2 = 144 + 8^2

s^2 = 144 + 64

s^2 = 208

s= 14.42inches

Hence the required length ix 14.42inches

How do I find the midpoint M C(3,-5) and D(7,9)

Answers

Given:

The two points are C(3,-5) and D(7,9).

To find:

The midpoint M of the given points.

Solution:

We know that,

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the midpoint formula, the midpoint of C(3,-5) and D(7,9) is

[tex]M=\left(\dfrac{3+7}{2},\dfrac{-5+9}{2}\right)[/tex]

[tex]M=\left(\dfrac{10}{2},\dfrac{4}{2}\right)[/tex]

[tex]M=\left(5,2\right)[/tex]

Therefore, the midpoint M of two points C(3,-5) and D(7,9) is (5,2).

Sine cannot be greater than 1.

The given conditions cannot form a triangle, there is no possible value of K.

What is sine law?

In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.

We need to find value of ∠K,

So, using the sine law,

Sin K / k = Sin J / j = Sin I /i

So,

Sin K / k = Sin J / j

Sin K / 64 = Sin 68° / 17

Sin K = 3.5

K = Sin⁻¹(3.5)

K = ERROR

Hence, the given conditions cannot form a triangle, there is no possible value of K.
