Of(x) = 6+2Lx-1), where x > 0
O (x) = 6+2[x+1), where x > 0
Of(x) = 6+2x+1), where x > 0

Answer:

Option B is correct.

Step-by-step explanation:

[tex]\sqrt[5]{32x^5y^10z^15}[/tex]

We need to solve the above expression.

32 = 2x2x2x2x2 = 2^5

and we know 5√ = 1/5

solving

[tex]=\sqrt[5]{2^5x^5y^{10}z^{15}}\\=(2^5)^{1/5}(5x^5)^{1/5}(y^{10})^{1/5}(z^{15})^{1/5}\\=2xy^2z^3[/tex]

So, simplified form is 2xy^2z^3

So, Option B is correct.

a = interest rate of first CD

b = interest rate of second CD

[tex]\bf a-b=3\qquad \implies \qquad \boxed{b}=3+a~\hfill \begin{cases} \left( \frac{a}{100} \right)X=240\\\\ \left( \frac{b}{100} \right)X=360 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \left( \cfrac{a}{100} \right)X=240\implies X=\cfrac{240}{~~\frac{a}{100}~~}\implies X=\cfrac{24000}{a} \\\\\\ \left( \cfrac{b}{100} \right)X=360\implies X=\cfrac{360}{~~\frac{b}{100}~~}\implies X=\cfrac{36000}{b} \\\\[-0.35em] ~\dotfill\\\\[/tex]

[tex]\bf X=X\qquad thus\qquad \implies \cfrac{24000}{a}=\cfrac{36000}{b}\implies \cfrac{24000}{a}=\cfrac{36000}{\boxed{3+a}} \\\\\\ (3+a)24000=36000a\implies \cfrac{3+a}{a}=\cfrac{36000}{24000}\implies \cfrac{3-a}{a}=\cfrac{3}{2} \\\\\\ 6-2a=3a\implies 6=5a\implies \cfrac{6}{5}=a\implies 1\frac{1}{5}=a\implies \blacktriangleright 1.2 = x\blacktriangleleft[/tex]

[tex]\bf \stackrel{\textit{since we know that}}{b=3+a}\implies b=3+\cfrac{6}{5}\implies b=\cfrac{21}{5}\implies b=4\frac{1}{5}\implies \blacktriangleright b=4.2 \blacktriangleleft[/tex]

Answer:

h(1) = 1.81 and h(2) = 21.44

Step-by-step explanation:

* Lets read the problem and solve it

- Evaluate means find the value, so evaluate h(x) means find the value

 of it at the given values of x

∵ h(x) = 2.8x³ + 0.01x² - 1

∵ x = 1 and x = 2

- Then find h(1) by substitute x by 1 and find h(2) by substitute x by 2

# At x = 1

∴ h(1) = 2.8(1)³ + 0.01(1)² - 1

∴ h(1) = 2.8(1) + 0.01(1) - 1

∴ h(1) = 2.8 + 0.01 - 1

∴ h(1) = 1.81

# At x = 2

∴ h(2) = 2.8(2)³ + 0.01(2)² - 1

∴ h(2) = 2.8(8) + 0.01(4) - 1

∴ h(2) = 22.4 + 0.04 - 1 ⇒ simplify

∴ h(2) = 21.44

* h(1) = 1.81 and h(2) = 21.44

Answer:

[tex]y = \frac{1}{2}x+10[/tex]

Step-by-step explanation:

The given path is:

y = -2x+5

Comparing with the standard form of equation:

y = mx+b

So,

m = -2

We know that product of slopes of two perpendicular lines is -1

Let m1 be the slope of the perpendicular line

m*m1=-1

-2*m1 = -1

m1 = -1/-2

m1 = 1/2

So the slope of perpendicular path is 1/2.

Since the new path passes through (-2,9)

[tex]9 = \frac{1}{2}(-2) +b\\9 = -1 +b\\b = 10[/tex]

Putting the values of m and b in standard form

[tex]y = \frac{1}{2}x+10[/tex]

Hence the equation of new path is:

[tex]y = \frac{1}{2}x+10[/tex] ..

Option: B is the correct answer.

         B)    [tex]\dfrac{24}{25}[/tex]

We know that the cosine trignometric ratio corresponding to a angle theta(θ) is defined as the ratio of the adjacent side to the angle theta to the hypotenuse of the triangle containing θ as one of the angle.

By looking at the figure we observe that the triangle is a right angled triangle and the length of the side adjacent to angle 16° is: 24 and the hypotenuse of the triangle is: 25.

Hence, we get:

[tex]\cos 16=\dfrac{24}{25}[/tex]

According to the given figure, the value of Cos 16° = 24/25.

Hence the correct option is B.

Given that a right triangle with hypotenuse 25, base 24 and the perpendicular is 7 units.

We need to find the value of Cos16°.

To find the value of cos(16°) in the given right triangle, we can use the trigonometric ratio for cosine:

cos(θ) = adjacent side / hypotenuse

In this case, θ = 16°, and we know the adjacent side is the base of the right triangle, which is 24 units, and the hypotenuse is 25 units.

Now, plug the values into the formula:

cos(16°) = 24 / 25

Hence the value of Cos(16°) = 24 / 25

Hence the correct option is B.

Answer:

x = 4 ± 3[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Given

4(x - 4)² - 180 = 0 ( add 180 to both sides )

4(x - 4)² = 180 ( divide both sides by 4 )

(x - 4)² = 45 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{45}[/tex] = ± 3[tex]\sqrt{5}[/tex]

Add 4 to both sides

x = 4 ± 3[tex]\sqrt{5}[/tex]

The value of x is equal to [tex]4 +3\sqrt{5}[/tex] and [tex]4 -3\sqrt{5}[/tex] by solving the quadratic equation that is taking the square root of both sides and also by using the concept of transposition.

Given the quadratic equation [tex]4(x-4)^2-180=0[/tex] by taking the square root of both sides

To solve a quadratic equation [tex]4(x-4)^2-180=0[/tex] by taking the square root of both sides, follow steps:

Step 1: Consider the given quadratic equation:

[tex]4(x-4)^2-180=0[/tex]

Add by  18  on both sides, gives;

[tex]4(x-4)^2-180+180=0+180[/tex]

On operating algebra sum results:

[tex]4(x-4)^2=180[/tex]

Step 2: Isolate the LHS [tex]4(x-4)^2[/tex]  from number 4 by dividing both sides by 4 yields:

[tex]\frac{4(x-4)^2}{4} =\frac{180}{4}[/tex]

On cancelation of 4 on LHS and divide 180 by 4 on RHS results in :

[tex](x-4)^2=45[/tex]

Factorize RHS with a perfect square 9 :

[tex](x-4)^2=9\times5[/tex]

Step 3: Taking the square root of both sides results :

[tex]\sqrt{(x-4)^2} = \sqrt{9\times5}[/tex]

On taking square roots results:

[tex](x-4) = \pm3\sqrt{5}[/tex]

Add by 4 on both sides, gives:

[tex]x=4 \pm3\sqrt{5}[/tex]

Therefore, the value of x is equal to [tex]4 +3\sqrt{5}[/tex] and [tex]4 -3\sqrt{5}[/tex] by solving the quadratic equation that is taking the square root of both sides and also by using the concept of transposition.

Answer:

19 red beads

Step-by-step explanation:

We first need to find a common denominator of 4/9, 1/5 and 1/4.

The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.

Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.

Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.

Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.

180 - (silver+gold+blue) = red beads

180-161 = 19 red beads b/c ----->

80+36+45+19 = 180

To find the estimate of beads that are red, you add the fractions of silver, gold, and blue beads first and subtract that from the total. In this case, it is estimated that the red beads are 19/180 of Julia's total collection.

To find the fraction of the red beads that Julia collects for her craft projects, we first need to sum up the fractions of the silver, gold, and blue beads as these are given fractions.

By addition, we have 4/9 (silver beads) + 1/5 (gold beads) + 1/4 (blue beads). Add these fractions together to get the total fraction of non-red beads. Now, to get the fractions into a form that's easier to add, find the least common denominator (LCD).

The LCD of 9, 5, and 4 is 180. Then, convert each fraction to have this denominator: 80/180 (silver) + 36/180 (gold) + 45/180 (blue). Now you can add these fractions directly to get 161/180.

Since the total should be 1 (or 180/180 to keep the denominator constant), to find the fraction of the red beads, subtract the sum of the other beads from 1. Thus, 1 - 161/180 = 19/180. Therefore, Julia’s collection consists of approximately 19/180 red beads.

Answer: 300 feet

Step-by-step explanation:

Note that:

Step-by-step explanation:

You have an arithmetic sequence in which

a₁ =  90

a₂ = 120

a₃ = 150

1. Calculate the explicit formula

This is an arithmetic sequence, because there is a constant difference of 30 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,  

aₙ = 90 + 30(n - 1) = 90 + 30n - 30

aₙ = 30n + 60

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

(1)

let (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 4), then

m = [tex]\frac{4+1}{4-0}[/tex] = [tex]\frac{5}{4}[/tex]

Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = [tex]\frac{5}{4}[/tex] x - 1 ← in slope- intercept form

(2)

let (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (1, - 6), then

m = [tex]\frac{-6-3}{1-4}[/tex] = [tex]\frac{-9}{-3}[/tex] = 3, hence

- SAS similarity : In two triangles, if two sets of corresponding sides  

   are proportional and the included angles are equal then the two  

   triangles are similar.

- Example : In triangle ABC and DEF, if m∠A = m∠D and  

  AB/DE = AC/DF then the two triangles are similar by SAS

* Lets solve the problem

- In Δ ABC and Δ DEF

∵ AB/DE = BC/EF = 1/2

- That means two sets of corresponding sides are proportion

∵ AB is a vertical side and BC is a horizontal side

∵ DE is a vertical side and EF is a horizontal side

∵ Horizontal and vertical lines are perpendicular

∴ AB ⊥ BC and DE ⊥ EF

- So angles B and E are right angles by definition of perpendicular

   lines

∵ All right angles are congruent

∴ m∠B = m∠D

∵ The two triangles have two sets of corresponding sides are

  proportion and the included angles are equal then the two

  triangles are similar

∴ △ABC ~ △DEF by the SAS similarity theorem

Answer:

1. Perpendicular

2. B and E

3. Congruent

Step-by-step explanation:

Horizontal and vertical lines are always perpendicular. So, the answer for the first gap is PERPENDICULAR.

Line BC is horizontal line, line AB is vertical line, so lines BC and AB are perpendicular and, therefore, angle B is right angle. Line EF is horizontal line, line ED is vertical line, so lines EF and ED are perpendicular and, therefore, angle E is right angle. So, answer for the second option is angles B and E.

Every two right angles are congruent.

Having two pairs of proportional sides and a pair of congruent adjacent angles, you can apply SAS similarity Postulate.
