Answer:

AB = 15 ÷ 2

Step-by-step explanation:

The computation of the AB is shown below;

Given that

AX : XB as AB : AC

AX = 5

XB = 4

AC = 6

AB = x

Based on the above information

We can write as

5 : 4 as to x : 6

ratios can be written as fractions

5 ÷ 4 = x ÷ 6

(4)(x) = (5)(6)

4x = 30

x = 30 ÷ 4

x = 15 ÷ 2

Hence, the AB = 15 ÷ 2

Given:

[tex]y=2x^2-8x-10[/tex]

To find:

The interval(s) on which the given function is positive.

Solution:

We have,

[tex]y=2x^2-8x-10[/tex]

[tex]y=2(x^2-4x-5)[/tex]

[tex]y=2(x^2-5x+x-5)[/tex]

[tex]y=2(x(x-5)+1(x-5))[/tex]

[tex]y=2(x+1)(x-5)[/tex]

For zeroes, [tex]y=0[/tex]

[tex]2(x+1)(x-5)=0[/tex]

[tex]x=-1,x=5[/tex]

-1 and 5 divide the number line in three parts [tex](-\infty , -1),(-1,5),(5,\infty )[/tex].

Interval        Selected Value      [tex]y=2(x+1)(x-5)[/tex]                      Sign

[tex](-\infty,-1)[/tex]                -2                  [tex]y=2(-2+1)(-2-5)=14[/tex]           +

[tex](-1,5)[/tex]                     0                   [tex]y=2(0+1)(0-5)=-10[/tex]              -

[tex](5,\infty)[/tex]                       6                  [tex]y=2(6+1)(6-5)=14[/tex]                 +

So, the function is positive for interval [tex](-\infty,-1)[/tex] and [tex](5,\infty)[/tex].

We can say that the function is positive for interval x < -1 and x > 5.

Therefore, the correct option is B.

:)

Answer:

Step-by-step explanation:

Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.

Write it out in a line: 3m + 12 - 8m -2

Simplify: -5m +10

Divide by -5 again to simplify further: m - 2

Answer:

=7m+30

Step-by-step explanation:

Distribute:

=(3)(m)+(3)(2)+(4)(6)+(4)(m)

=3m+6+24+4m

Combine Like Terms:

=3m+6+24+4m

=(3m+4m)+(6+24)

=7m+30

Answer:

69

Step-by-step explanation:

Recall that

tan²(x) + 1 = sec²(x)

for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)

Then

tan²(Φ) + sec²(Φ) = 3

tan²(Φ) + (tan²(Φ) + 1) = 3

2 tan²(Φ) + 1 = 3

2 tan²(Φ) = 2

tan²(Φ) = 1

tan(Φ) = ±√1

tan(Φ) = 1   or   tan(Φ) = -1

Φ = tan⁻¹(1) + n 180°   or   Φ = tan⁻¹(-1) + n 180°

Φ = 45° + n 180°   or   Φ = -45° + n 180°

The first family of solution is the set of angles

{…, -315°, -135°, 45°, 225°, 405°, …}

and the second family is the set

{…, -405°, -225°, -45°, 135°, 315°, …}

(showing the solutions for n = -2 to n = 2)

You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that

Φ = 45° + n 90°

If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then

Φ = 45°, 135°, 225° or 315°

Answer:

60 more cubes are needed

Answer:

-6

Step-by-step explanation:

-3a + 4 = -14

-3a = -14 - 4

-3a = -18

a = -18 / 3

a = -6

Answer:

a = 6

Step-by-step explanation:

Step 1: Subtract 4 from both sides.

-3a + 4 - 4 = -14 - 4

+4 and -4 cancel out.

Step 2: Subtract 4 from -14 to get -18.

-3a = -18

Step 3: Divide both sides by -3.

a = -18/-3

Step 4: Divide -18 by -3 to get 6.

a = 6

Let's check our work by substituting a for 6.

-3(6) + 4 = -14

Multiply -3 by 6 to get -18.

-18 + 4 = -14

Add -18 and 4 to get -14.

-14 = -14

This is true, so a = 6.

Answer:

x=3

Step-by-step explanation:

-5(-6-3x)+8=83

Distribute the -5 to both terms in the parentheses by multiplication, multiply the -5 by the -6 and the -3x.

30+15x+8=83

Add like terms, add the 30 and the 8.

38+15x=83

Subtract 38 from both sides to isolate the x on the left side.

15x=45

Divide by 15 on both sides to solve for x.

x=3

Answer:

4 : 1

Step-by-step explanation:

(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.

1 day = 24 hours, 3 days = (3 × 24) hours

3 days = 72 hours

Now both the units are same, so we can easily simplify now.

72 hours : 18 hours

36 : 9 = 12 : 3

= 4 : 1 ( Answer)

Answer:

 [tex]AnB=(5,6,7,8,9)[/tex]

[tex](AUB)=(5,\infty) U (-\infty,9)[/tex]

Step-by-step explanation:

From the question we are told that

A= {z│z > 4}

B= {z│z ≤ 9}

Generally A&B are assumed to be really integers

therefore

A={5,6,7,8,.....}={z│z > 4}

B=(9,8,7,6.....)={z│z ≤ 9}

a)For [tex]AnB[/tex]

Mathematically the [tex]AnB[/tex] is given as

[tex]AnB[/tex]=[tex]A=(5,6,7,8,9,10......) n B=(9,8,7,6,5,4,3,2,1......)[/tex]

[tex]AnB[/tex]=(5,6,7,8,9)

Therefore the intercept [tex]AnB[/tex]  is Given as

[tex]AnB=(5,6,7,8,9)[/tex]

b) for [tex]AuB[/tex]

Mathematically the [tex]AuB[/tex] is given as

[tex]AuB[/tex]=[tex]A=(5,6,7,8,9,10......) U B=(9,8,7,6,5,4,3,2,1......)[/tex]

[tex]AuB[/tex]= [tex](5,\infty) U (-\infty,9)[/tex]

Therefore the union [tex]AuB[/tex] i given as

[tex]AuB[/tex]= [tex](5,\infty) U (-\infty,9)[/tex]

Answer:

1.5

Step-by-step explanation:

When we divide two fractions, such as 3/4 ÷ 1/2, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

We also simplify the answers to fraction problems whenever possible.

Answer: 3/2 or 1 and 1/2

Step-by-step explanation: Remember that dividing by a fraction

is the same thing as multiplying by the reciprocal of the fraction.

The reciprocal of a fraction is just that fraction flipped.

So 3/4 ÷ 1/2 can be rewritten as 3/4 × 2/1.

Before multiplying however, notice that we

can cross-cancel the 2 and 4 to get 1 and 2.

Finally, multiplying across the numerators and

across the denominators, we have 3/2 or 1 and 1/2.

Answer:

825

Step-by-step explanation:

Calculation for what The frequency in this interval is equal to:

Using this formula

Frequency=Population size*Relative frequency interval

Let plug in the formula

Frequency=5,500 observations*0.15

Frequency=825

ThereforeThe frequency in this interval is equal to:825

The frequency in this interval is equal to 825.

Given

A population is of size 5,500 observations.

When the data are represented in a relative frequency distribution, the relative frequency of a given interval is 0.15.

The frequency is defined as the product of population size and relative frequency interval.

The following formula is used to calculate frequency in this interval is;

[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\Frequency= 5500\times 0.15\\\\Frequency= 55\times 15\\\\Frequency= 825[/tex]

Hence, the frequency in this interval is equal to 825.
