B edge 2020

Step-by-step explanation:

Answer:

x=-26

Step-by-step explanation:

Distributive property first (both sides)

you would get

4x+2 = 3x-24

next you will subtract 3x from both sides

1x+2=-24

add 24 to both sides

1x+26=0

move 26 to the other side but since you flipped it you have to make it negative

x=-26

Answer:

Step-by-step explanation:

     ____

a) 0.36   = 0.3636........    

x = 0.363636.......    

{After decimal two digits are there and both are repeated. So, multiply both side by 100}

100x = 36.3636.......  equ(i)

    x =   0.3636......   equ(ii)   {Now, subtract equ (ii) form (i)

99x  = 36

x = 36/99

x = 4/11

0.3636...... = 4/11

B)    __

 0.36     = 0.366666.....

{After decimal point two digits are there but only one digit, 6 is repeated. so first multiply both sides of equation [x=0.366...] by 100 and mark it as equation (i) and then multiply both sides of the equation [x=0.366...] by 10 and mark it as (ii) equation }

x = 0.3666....

100x = 36.66666.....     ---------- (i)

10x  =    3.66666......      ---------(ii)  {Now subtract (ii) from (i)}

90x = 33

x = 33/90

x = 11/30

0.36666..... = 11/30

c)

[tex]0.36=\frac{36}{100}\\\\= \frac{9}{25}[/tex]

The key characteristics of graph of f(x) = cosecx are, The range of the function is (−∞, −1]∪[1, ∞) and Asymptotes occurs every π, beginning at x = 0. So statements 1 & 3 are correct

Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.

There are 6 commonly used functions in trigonometry with their name and abbreviations-

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)

Given that,

A trigonometric function,

f(x) = cosecx

The range of cosecx is (−∞, −1]∪[1, ∞)

At x = 0, it is approaching to infinity from both the sides

So, y intercept is not 1

At every π interval, it has Asymptotes

It never intersects the x axis, So x-intercept is not exist here

Hence, statements 1 & 3 are correct

The graph of f(x)=cscx has a range of (−∞, −1]∪[1, ∞) , no y-intercept, and asymptotes at every multiple of \pi, but no x-intercepts.

The key characteristics of the graph of the function f(x)=cscx include the following:

This is because the cosecant function is the reciprocal of the sine function, which ranges from -1 to 1.

So, the cosecant function will take on all values that are less than -1 or greater than 1.

The sine function, which is the reciprocal of the cosecant, equals 0 at this point, and division by zero is undefined.

since cosecant is the reciprocal of sine, the function is undefined at these points;

so statement c is incorrect.

Answer:

225

Step-by-step explanation:

Using the basic components of summation ∑

∑n = [tex]\frac{1}{2}[/tex] n(n + 1) and ∑1 = n

Thus

∑ (2n - 1) ← for n = 1 to 15

= ∑2n - ∑1

= 2∑n - ∑1

= 2 ([tex]\frac{1}{2}[/tex] n(n + 1)) - n

= n(n + 1) - n ← Evaluate for n = 15 ( the upper value )

= 15 × 16 - 15

Answer:

771.4 units^3

Step-by-step explanation:

Formula for volume of a cylinder = V=πr^2h

Plug in the numbers to solve for the height (note: the height of an oblique or slanted cylinder is the same as a regular right cylinder)

2314.25 = π(8.9)^2 h

h=9.3

Then plug the height into the formula for a pyramid

V = 1/3πr^2

V = 1/3 π (8.9)^2 (9.3)

V = 771.4 units ^3

       7x + 2 = 7

             - 2  - 2

              7x = 5

              ---    ---

               7     7

                x = 5/7

Step 3; Plug x into y=x+1

y = 5/7 + 1

y = 12/7

Answer:

{(5/7 , 12/7)}

Step-by-step explanation:

First plug y into one of the x's

5x + 2(x + 1)  = 7

Now solve for X

5x + 2x + 2 = 7

Combine like terms

7x + 2 = 7

Subtract 2 from each side

7x = 5

Divide to get x by itself

x = 5/7

Now plug that into the second equation for x

y = 5/7 + 1

now just solve it

y = 12/7 if they want it simplified then it's 1 5/7

Zachary ran faster with 4 minutes per lap compared to Khloe's 3 minutes per lap.

To compare the speeds of Khloe and Zachary, we need to find their respective speeds in terms of minutes per lap.

Khloe ran around the track 7 times in 21 minutes, so her speed is [tex]\( \frac{21}{7} = 3 \)[/tex] minutes per lap.

Zachary took 4 minutes to run around the track once, so his speed is [tex]\( 4 \)[/tex] minutes per lap.

Comparing their speeds, Zachary's speed is faster at 4 minutes per lap, whereas Khloe's speed is 3 minutes per lap.

In summary, Zachary ran faster than Khloe because he completed each lap in 4 minutes compared to Khloe's 3 minutes per lap.

The number of games played is 9

Let the number of games played = g

Amount of bet per game = $2

Number of games won by Marty = 4

Number of games won by Wendy will be;

Amount won by Wendy = $10

This means ;

cost per bet × number of games won by Wendy = 10

2(g - 4) = 10

2g - 8 = 10

2g = 18

g = 9

Hence, They played 9 games.

The equation that has the solution x = 4 is [tex]log_ 4 (3x+4) = 2[/tex].

Option A is the correct answer.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We also find the solution in a system of equations using the substitution or elimination method.

Example:

2x + 4 = 8

The solution is x = 2.

We have,

To find which equation has x = 4 as the solution,

We can substitute x = 4 into each equation and see which one gives a true statement.

Now,

[tex]log_4 (3x+4) = 2\\log_3 (2x-5) = 2\\log_x 64 = 4\\log_x 16 = 4[/tex]

We can write it as,

4² = 3x + 4

16 = 3x + 4

16 - 4 = 3x

3x = 12

x = 4

3² = 2x - 5

9 = 2x - 5

9 + 5 = 2x

14 = 2x

x = 7

[tex]x^4[/tex] = 64

x = [tex]64^{1/4}[/tex]

[tex]x^4[/tex] = 16

x = 16[tex]16^{1/4}[/tex]

x = 2

Step-by-step explanation:

Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:

[tex]Speed(S) = \frac{distance(d)}{time(t)}\\ S=\frac{d}{t}[/tex]

plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.

The time spent (t₁) in going east is given by:

[tex]S=\frac{d}{t_1}\\ t_1=\frac{d}{S} =\frac{d}{400mph}[/tex]

The time spent (t₂) in going east is given by:

[tex]S=\frac{d}{t_2}\\ t_2=\frac{d}{S} =\frac{d}{280mph}[/tex]

The total time (t) = t₁ + t₂

t = t₁ + t₂ = 8.5 hours

[tex]\frac{d}{400}+\frac{d}{280} =8.5\\280d+400d=952000\\680d=952000\\d=1400miles\\[/tex]

Therefore the one way distance is 1400 miles

You can find that because on the graph, the top of the curve is on Y and its positive. Its at positive 4 so its positive......sorry im not good at explaning hope this helped.....also you can check google images or videos and it explanes.

Answer:

Positive

Step-by-step explanation:

In order to answer this question, we need to figure out the equation of the quadratic.

We see that the vertex is at (0, 4) and that the points (1, 3) and (2, 0) are on the graph. The generic quadratic is: ax^2 + bx + c, so we can just plug in these three points to find a, b, and c:

4 = 0 + 0 + c  ⇒  c = 4

3 = a + b + c = a + b + 4  ⇒  a + b = -1

0 = 4a + 2b + c = 4a + 2b + 4  ⇒  4a + 2b = -4

We now have two linear equations (a + b = -1 and 4a + 2b = -4) so multiply the first one by 2 and subtract it from the second:

  4a + 2b = -4            ⇒             4a + 2b = -4

- 2(a + b) = (-1) * 2       ⇒         -   2a + 2b = -2

______________     ⇒       ______________

Our difference is 2a = -2, so a = -1. Plug this back in to find b: a + b = -1.

-1 + b = -1

b = 0

So our equation is -x^2 + 4 = 0.

The discriminant is just b^2 - 4ac. Here, it is: 0^2 - 4 * (-1) * (4) = 16.

So the discriminant is positive.

Hope this helps!
