The x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

The x-intercept of the function is the point or points where the graph of the function crosses the x-axis i.e. the point where the function equals 0

The function is given as

f(x) = cos(x)

And the interval is given as

[0, 2)

The above means that we determine the value of x when the function f(x) equals 0

So, we have

cos(x) = 0

The above equation can be solved graphically

See attachment for the graph of the function f(x) = cos(x)

In the interval [0, 2), the graph crosses the x-axis at points x = π/2 and 3π/2

Hence, the x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

The information illustrated that A. there is a small difference in the mean number of stray cats placed in homes buy a new lease on life animal clinic each week and the mean number of stray cats placed in homes by no raft staff animal hospital each week.

A mean or average is the ratio of the sum of observations to the number of observations.

For the first case:

Mean = (13*5 + 14*10 + 15*19 + 16*13 + 17*4)/75 = 10.21

For the second case:

Mean =(3*2 + 4*10 + 5*21 + 6*11 + 7*5 + 8*3)/33 = 10.48

Therefore, it should be noted that there is a small difference in the mean number of stray cats placed in homes buy a new lease on life animal clinic each week and the mean number of stray cats placed in homes by no raft staff animal hospital each week.

According to the equation does the graph of the systems of equations solve is B.

1/3x+1=2x-4 is correct.

A graph is a structure consisting of a group of items, some of which are "linked." The objects are mathematical abstractions known as vertices, and each pair of connected vertices is known as an edge.

It is evident from the graph that the two lines intersect at the location:

(3, 2).

To put it another way,

at x =3, y = 2

The point where two lines intersect is:

(x, y) = (3, 2) (3, 2).

Now,

x = 3 is the point  of the x-coordinate

y = 2 is the point of the y-coordinate

Now, examine the equation, 1/3x+1=2x-4, to see if it contains the correct x-coordinate value.

(1/3)x + 1 = 2x -4

subtracting 1 from both side:

(1/3)x + 1 -1  = 2x -4 -1

We get:

(1/3)x = 2x -5

subtract 2x from both sides:

(1/3)x -2x = 2x -5 -2x

We get:

-(5/3)x = -5

on simplifying the equation we get:

x = 3

the value of x = 3

this show that the 1/3x+1=2x-4 is correct.

The time taken for Maria to do the job by herself is 3/4 of a hour which is 45 minutes.

It should be noted that it was stated that Maria and her little sister Anita used 1/2 of an hour to shovel the snow off of the sidewalks on their street and that this is 2/3 of the time it takes Maria to do the same job by herself.

Therefore, the time taken for Maria to do the job will be represented by x

Therefore, 2/3x = 1/2

Divide

x = 1/2 ÷ 2/3

x = 1/2 × 3/2

x = 3/4

Therefore, the time taken for Maria to do the job by herself is 3/4 of a hour which is 45 minutes.

Step-by-step explanation:

a) 4

b) 4

c) 4

d) DNE

why is that ? as there is a hollow dot in the curve exactly at x = -3, there is no defined functional value for x = -3.

but it is only this one specific dot that is excluded. so, the lim calculation can still use it for a) - c). although it changes direction there, it is still the same coming from left or from right. and therefore it is the same limit overall.

e) 1

f) -1

g) DNE

h) 1

at x = 0 the function has a jumping discontinuity. therefore, the limits are different when coming from left or from right. and because of this difference, the general limit does not exist. the functional value at x = 0 is part of the curve coming from the left.

i) 2

j) DNE

similar to a) - d). the point (but only the single point) at x = 2 is excluded from the function and has no assigned functional value. nevertheless, it can still be used for the limit calculation.

k) it is not very well to see in the picture. when coming from the right, it appears to be 3.

but it might be possible that it goes further down to 2.

l) similar to k) it is not good to see in the picture. when coming from the left, is the wild "swinging" ending at 2 ? or going back up to 3 to meet the functional curve of k) ?

I would suspect it is 3, but it could be 2.

you need to decide k) and l) when you look at your original, because the picture is too fuzzy to be sure.

The area and circumference of a circle is 40.8cm² and 22.6 cm respectively.

What is meant by a circle's circumference?

AB = r = √(5-2)²+(3-1)²

r = √9 + 4

r = √13

r = 3.605

Determine the circumference

C = 2(3.14)(3.605)

C = 22.6394

Hence the circumference of the circle is 22.6 cm

Determine the area

Area = πr²

Area = 3.14 * 3.605 * 3.605

Area = 40.8cm²

Hence the area and circumference of a circle is 40.8cm² and 22.6 cm respectively.

The exam has 35, 2-point questions, and 15 5-point questions solved by linear equations.

A linear equation is an equation with only one variable. It has the formula Ax + B = 0, where A and B can be any two real values, and x is an unsolved variable.

Let us assume there are x 2-points question, so there are x-50 5-points question .

Hence total no of points: 2×x+5×(50-x)=145 points

This forms a linear equation in x.

Now let us solve the linear equation in x to get the number of 2 mark questions.

2x+250-5x=145

or, -3x=-105

or, x=-105/-3

or, x=35

There are 35 2-points questions

Remaining questions 50-35=15

Hence there are 15 5-points questions.

Solving the linear equation we get 35 2 point questions and 15 5 point questions.

Since the point V is located on line segment UW, the length of the line segment UW is 9 units

From the question, we have the following parameters:

Point V is located on line segment UW

And the lengths are

UV= 3 units

VW = 6 units

Because the point V is located on line segment UW, then we have

UW = UV + VW

This gives

UW = 3 + 6

Evaluate the sum

UW = 9
