Answer:

[tex]\textsf{length}=6x - 1[/tex]

[tex]\textsf{width}=x+3[/tex]

Step-by-step explanation:

Area of a rectangle = length × width

Given area:  [tex]A=6x^2+17x-3[/tex]

Therefore,  [tex]6x^2+17x-3=\sf length \cdot width[/tex]

To find the length and width, we need to factorize the given expression for area.

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]

Find 2 two numbers (d and e) that multiply to ac and sum to bRewrite b as the sum of these 2 numbers: d + e = bFactorize the first two terms and the last two terms separately, then factor out the comment term.

[tex]6x^2+17x-3 \implies a=6, b=17, c=-3[/tex]

[tex]ac=6 \cdot -3=-18[/tex]

[tex]d+e=17[/tex]

So we are looking for a pair of numbers that multiply to -18 and sum to 17.

Factors of 18: 1, 2, 3, 6, 9, 18

Therefore, the two numbers (d and e) that multiply to -18 and sum to 17 are:

18 and -1

Rewrite [tex]17x[/tex] as [tex]+18x-x[/tex]:

[tex]\implies 6x^2+18x-x-3[/tex]

Factor first two terms and last two terms separately:

[tex]\implies 6x(x+3)-1(x+3)[/tex]

Factor out common term [tex](x+3)[/tex]:

[tex]\implies (6x-1)(x+3)[/tex]

As length > width,

[tex]\textsf{length}=6x - 1[/tex]

[tex]\textsf{width}=x+3[/tex]

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is

prime". Let B be the event "the outcome is a divisor of 3". Find P(A|B).

Answers

Answer:


P(A|B) = 0.5


Step-by-step explanation:


A: set of prime numbers ={1,2,3}


B: set of divisors of 3 ={1,3}


P(A)=P(1)+P(2)+P(3)= 0.1+0.1+0.3 =0.5


P(B)=P(1)+P(3)=0.1+0.3=0.4


P(A|B) means: probability of A knowing that B


In other words we have to find the probability that a prime outcome occurs knowing that it is a divisor of 3


Its formula is given by:


P(A|B) = P(AintersectionB) /P(B)


A intersection B: outcome is prime and a divisor of 3 at the same time. (common elements between sets A and B)


A int B= {1,3}


P(AintB)= P(A)xP(B) = 0.5x0.4=0.2


Now back to the formula:


P(A|B) =P(AintB) / P(B)


=0.2/0.4=0.5

Identify the trinomial that is a perfect square.

B. 16x2 + 20x + 9
C. 36x2 + 60x + 25
D. 4x2 + 30x + 25

Answers

Answer:

Option C, [tex]36x^2 + 60x + 25[/tex]

Step-by-step explanation:

Step 1:  Determine the perfect square

According to online, "When an expression has the general form a²+2ab+b², then we can factor it as (a+b)². For example, x²+10x+25 can be factored as (x+5)². This method is based on the pattern (a+b)²=a²+2ab+b², which can be verified by expanding the parentheses in (a+b)(a+b)"

The only one that seems to work is Option C so lets factor it.

[tex]36x^2 + 60x + 25[/tex]

[tex](6x + 5)(6x + 5)[/tex]

[tex](6x + 5)^2[/tex]

Yup!  We can see that Option C would give us a perfect square

Answer:  Option C, [tex]36x^2 + 60x + 25[/tex]

Gretchen made a paper cone to hold a gift for a friend. The paper cone was 15 inches high and had a radius of 2 inches. Find the volume of the paper cone to the nearest tenth. Use 3.14 for π.

Answers

Answer

91.67inch^3

Step-by-step explanation:

The volume of a cone can be calculated using below formula

V= 1/3 π.r^2h

Where h= height of the cone

r= radius of the cone

V= volume of the cone

Given :

height= 11 inches

radius= 5 inches

π= 3.14

Then substitute into the formula we have

V= 1/3 × 3.14× 5^2 ×11

V= 91.67inch^3

Therefore volume of the cone is 91.67inch^3

If we have f(x) and it's inverse, and we compose them

we will get

[tex]f {}^{ - 1} (f(x) = x[/tex]

So here we compose

[tex]( \frac{1}{ \frac{1}{x} + 1 - 1} [/tex]

[tex] \frac{1}{ \frac{1}{x} } [/tex]

So the composition is x, so they are inverses.

Answers

Answer:

  a. exception: C; obtuse angle with a different measure

  b. corresponding angles are congruent; corresponding sides are proportional

  c. corresponding angles are congruent among the similar triangles; they are not congruent when the triangles are not similar

  d. corresponding sides are porportional; they are not proportional when the triangles are not similar

Step-by-step explanation:

As you know, similar triangles have congruent corresponding angles, and proportional corresponding sides. This gives them the same shape, but they may be of differenent sizes.

__

a.

Figure C appears to have a larger smallest angle and a smaller largest angle than the rest of the figures. Its long side relative to its second-longest side appears to be shorter, consistent with a smaller largest angle.

__

b.

The similar triangles have congruent corresponding angles and proportional corresponding sides.

__

c.

See (b) regarding similar triangles. Non-similar triangles have different angles.

__

d.

See (b) regarding similar triangles. Non-similar triangles have different side proportions.
