Answer:

We conclude that:

[tex]h\left(1\right)=6[/tex]      

Step-by-step explanation:

Given

The function is

[tex]h\left(x\right)\:=\:|1\:-\:7x|[/tex]

To determine

h(1) = ?

Given the function

[tex]h\left(x\right)\:=\:|1\:-\:7x|[/tex]

substitute x = 1 in the function

[tex]h\left(1\right)=\left|1-7\left(1\right)\right|[/tex]

[tex]h(1)=\left|1-7\right|[/tex]

[tex]h(1)=\left|-6\right|[/tex]

Apply absolute rule:   |-a| = a

[tex]h\left(1\right)=6[/tex]        

Therefore, we conclude that:

[tex]h\left(1\right)=6[/tex]

=  11 / ¹/₃

= 33 sections

Answer:

372.5 miles

Step-by-step explanation:

First, find how many miles she traveled at 65 mph:

65(2.5)

= 162.5

Then, find how many she traveled at 60 mph:

60(3.5)

= 210

Add these together:

162.5 + 210

= 372.5

So, Ella traveled 372.5 miles in total

Answer:

31°

Step-by-step explanation:

Answer:

1) Words learned=15x+75

2) 15 is the slope

3) 270 words

4) 21 weeks

Step-by-step explanation:

Let x be equal to the number of weeks that pass.

Let y be equal to the number of words we learn.

1) We're told that we learn 15 words per week. Therefore, 15x would equal the number of words we learn. However, because we already know 75, we add that to 15x, giving us this equation:

y=15x+75

2) The slope is the same thing as the rate of change in a situation. In this scenario, every week, we learn 15 words. Therefore, the rate of change, or the slope, is 15.

3) To find this, plug 13 into our equation as x and solve for y.

y=15x+75

y=15(13)+75

y=195+75

y=270

Therefore, we would learn 270 vocabulary words in total in 13 weeks.

4) To find this, plug 390 into our equation as y and solve for x.

y=15x+75

390=15x+75

Subtract 75 on both sides to isolate x

390-75=15x+75-75

315=15x

Divide both sides by 15

315/15=15x/15

21=x

Therefore, it would take 21 weeks to learn 390 new vocabulary words.

I hope this helps!

Answer:

1+√3

Step-by-step explanation:

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * AC * BD

We need to get AC

AC = AD+DC

Get base AD using SOH CAH TOA

tan 45 = 4/AD

AD = 4/tan45

AD = 4/1

AD = 4

Get DC

tan 30 = 4/DC

DC = 4/tan 30

DC = 4/(1/√3)

DC = 4√3

AC = 4 + 4√3

AC = 4(1+√3)

Get the Area of the triangle

Area = 1/2 * 4 *  4(1+√3)

Area of the triangle = 1+√3

Answer:

x = 10

Step-by-step explanation:

im pretty sure this is right. since the ratio is 5:6, if you multiply 6 x 2, you get 12. so 5 x 2 = 10

34 I think because 300-216=84 and 84-50=34

Answer:

See proof below

Step-by-step explanation:

From the given diagram, we can see that <2 and <3 lies on the same straight line, hence the sum of the angles is 180 degrees (supplementary)

<2 + <3 = 180 .... 1

Similarly. <1 and <2 are also supplementary angles

<1 + <2 = 180 .... 2

Subtract 1 from 2;

<3 - < 1 + <2 - <2 = 180 - 180

<3 - <1 +0 = 0

<3 - <1 = 0

Add <1 to both sides

<3 - <1 + <1 = 0+<1

<3 = <1 (Proved!)

This shows that <3 and <1 are equal

We can also conclude that <3 and <1 are vertically opposite angles and vertically opposite angles are equal

Answer:

  4·log(16) = 16·log(2) ≈ 4.81648

Step-by-step explanation:

The rules of logarithms are ...

  log(a^b) = b·log(a)

Here, we have ...

  log(16^4) = 4·log(16)

However, we recognize that 16 = 2^4, so this becomes ...

  log(16^4) = 4·(log(2^4)) = 4·4·log(2) = 16·log(2)

The base-10 logarithm of 2 is about 0.30103, so this is ...

  log(16^4) ≈ 16·0.30103 = 4.81648

Choose the form of the answer you need:

  log(16^4) = 4·log(16) = 16·log(2) ≈ 4.81648

Answer: 14

Step-by-step explanation:

Answer:

b = -3

Step-by-step explanation:

3.2b + 10 = -1.7b - 4.7

add 1.7b to each side

3.2b+1.7b + 10 = -1.7b+1.7b - 4.7

4.9b +10 = -4.7

Subtract 10 from each side

4.9b +10-10 = -4.7-10

4.9b = -14.7

Divide each side by 4.9

4.9/4.9 = -14.7/4.9

b = -3

Answer: 60%

Step-by-step explanation:

Sixth-graders that picked the museum = 39

Sixth-graders that picked the factory = 26

Total number of sixth graders = 39 + 26 = 65

Therefore, the percentage of the sixth-graders that picked the museum would be:

= Sixth-graders that picked the museum / Total number of sixth graders × 100

= 39/65 × 100

= 60%
