Answer:

6 2/3 x 1 1/2 is 10

Step-by-step explanation:

Answer:

1. Take the value of X and replace X with that value in the equation.

2. Now you solve Y.

This is simple as the perimeter is given. All you have to do is make an expression and then equate it to the perimeter.

Side lengths:

Shortest Side: [tex]x[/tex]

1st side: [tex]2x[/tex] (Given that it's twice the length of the shortest of twice of [tex]x[/tex])

3rd side: [tex]x + 19[/tex] (Given that it's 19 more than the length of the shortest side or [tex]x[/tex])

Since the perimeter is just the addition of all the sides of the shape, the perimeter is going to be the addition of all the expression we made.

So the final expression is going to be: [tex]x + 2x + x + 19[/tex]

This is nothing but the perimeter so we can therefore equate it to [tex]163[/tex]

[tex]x + 2x + x + 19 = 163[/tex]

Now we solve the equation. Here it goes!:

[tex]4x + 19 = 163\\4x = 163 - 19\\4x = 144\\x = 144/4 = 36[/tex]

Therefore, [tex]x = 36[/tex]

So now we plug them into the previous expressions we made for the sides and you get:

Shortest side: [tex]36[/tex]

1st side: [tex]72[/tex]

3rd side: [tex]55[/tex]

And also, the length of the shortest side is [tex]36[/tex] as mentioned previously :D

Answer:

Step-by-step explanation:

7x+5y=25

3x+2y=10

21x+15y=75

21x+6y=30

0x+11y=45

11y=45

y=45/11

y = 4.09

sub in 4.09 into equation 1

7x+5(4.09)=25

7x+20.45=25

7x=25-20.45

x=4.55/7

Step-by-step explanation:

the answer is D (y=16.9)

I divided 507 and 30 and got the answer 16.9.

if you would've put any other answer it would've been wrong because the answer had the 30 in it after it was divided.(not sure if its 100% correct)

Step-by-step explanation:

Hope this helped, Have a Wonderful Day!!

Answer:

x ≥ - 24

Step-by-step explanation:

Let's solve this with an equal sign and then decide how to handle the at least part.

3/4 x = -18              Multiply by 4

3/4 * 4 x = -18*4     Cancel the left, multiply the right.

3x = -72                  Divide by 3

x ≥ -24

You need  the greater than to indicate that 3/4 of a number can give something larger than - 18.

You need the equal sign to fulfill at least.

At least, in this question means "get larger."

so x > - 24

Answer:

Substitute the given value into the function and evaluate.

23 (y − 6) = −(y + 2) + 1 = y = 137/24

2 = y = 137/24

3 = y = 137/24

y − 6 = −(y + 2) + 1 = y = 5/2

Answer:

R3 <= 0.083

Step-by-step explanation:

f(x)=xlnx,

The derivatives are as follows:

f'(x)=1+lnx,

f"(x)=1/x,

f"'(x)=-1/x²

f^(4)(x)=2/x³

Simialrly;

f(1) = 0,

f'(1) = 1,

f"(1) = 1,

f"'(1) = -1,

f^(4)(1) = 2

As such;

T1 = f(1) + f'(1)(x-1)

T1 = 0+1(x-1)

T1 = x - 1

T2 = f(1)+f'(1)(x-1)+f"(1)/2(x-1)^2

T2 = 0+1(x-1)+1(x-1)^2

T2 = x-1+(x²-2x+1)/2

T2 = x²/2 - 1/2

T3 = f(1)+f'(1)(x-1)+f"(1)/2(x-1)^2+f"'(1)/6(x-1)^3

T3 = 0+1(x-1)+1/2(x-1)^2-1/6(x-1)^3

T3 = 1/6 (-x^3 + 6 x^2 - 3 x - 2)

Thus, T1(2) = 2 - 1

T1(2) = 1

T2 (2) = 2²/2 - 1/2

T2 (2) = 3/2

T2 (2) = 1.5

T3(2) = 1/6 (-2^3 + 6 *2^2 - 3 *2 - 2)

T3(2) = 4/3

T3(2) = 1.333

Since;

f(2) = 2 × ln(2)

f(2) = 2×0.693147 =

f(2) = 1.386294

Since;

f(2) >T3; it is significant to posit that T3 is an underestimate of f(2).

Then; we have, R3 <= | f^(4)(c)/(4!)(x-1)^4 |,

Since;

f^(4)(x)=2/x^3, we have, |f^(4)(c)| <= 2

Finally;

R3 <= |2/(4!)(2-1)^4|

R3 <= | 2 / 24× 1 |

R3 <= 1/12

R3 <= 0.083

Answer:

D. x = 21

Step-by-step explanation:

So a straight line is equal to 180º and that's what we're trying to figure out here. Set both equations to equal 180, it should look like:

5x + 4x - 9 = 180

Now we just solve!

5x + 4x - 9 = 180

5x + 4x = 9x

9x - 9 = 180

     +9     +9

------------------

9x = 189

Divide both sides by 9 to get x by itself.

189/9 = 21

x = 21

Answer:

if x = pi/2, then y =1.

if x = pi/4, then y = [tex]\frac{\sqrt{2 } }{2}[/tex]

if x = pi, then y = 0

Step-by-step explanation:

The required answer as a comma-separated lists are (0, 0),  ([tex]\frac{\pi}{6}[/tex], 0.5), ( [tex]\frac{\pi}{4}[/tex],  [tex]\frac{1}{\sqrt{2} }[/tex]),  ( [tex]\pi[/tex], 0)

Given the equation of a sine graph expressed as:

[tex]y=sinx[/tex] for all values of x within the range 0 < x < 2π

We need to get the value of y for the values of x within the range as shown:

If x = 0;

y = sin0

y = 0

The required solution is (0, 0)

If x = 30;

y = sin30

y = 0.5

The required solution is ([tex]\frac{\pi}{6}[/tex], 0.5)

If x = [tex]\frac{\pi}{4}[/tex];

y = sin [tex]\frac{\pi}{4}[/tex]

y = [tex]\frac{1}{\sqrt{2} }[/tex]

The required solution is ( [tex]\frac{\pi}{4}[/tex],  [tex]\frac{1}{\sqrt{2} }[/tex])

If x = [tex]\pi[/tex]

y = sin [tex]\pi[/tex]

y = 0

The required solution is at ( [tex]\pi[/tex], 0)

If x = [tex]2\pi[/tex]

y = sin[tex]2\pi[/tex]

y = 0

Hence the required answer as a comma-separated lists are (0, 0),  ([tex]\frac{\pi}{6}[/tex], 0.5), ( [tex]\frac{\pi}{4}[/tex],  [tex]\frac{1}{\sqrt{2} }[/tex]),  ( [tex]\pi[/tex], 0)

Answer:

Option 3 :

x → 7+, y → –[infinity]

Step-by-step explanation:

f(x) = (-2x² + 14)/(x² - 49)

x² - 49 = (x + 7)(x - 7)

Hence f(x) goes to infinity at x = - 7 or 7

x < - 7 = (-ve)(-ve) = + ve

=> x → –7–

Here, x² - 49 is + ve

-7 < x < 7 = (+ve)(-ve) = - ve

=> x → –7+ or x → 7– .

here, x² - 49 is - ve

x > 7 = (+ve)(+ve) = + ve

=> x → 7+

Here, x² - 49 is + ve

So (-2x² + 14) is - ve for all [ x → –7– , x → –7+ , x → 7– , x → 7+ ]

As,

-2(-7)² + 14 = -84 and -2(+7)² + 14 = -84

x → –7– = (-ve)/(+ve)

=> y → -[infinity].

x → –7+ or x → 7– = (-ve)/(-ve)

=> y → [infinity]

x → 7+ = (-ve)/(+ve)

=> y → -[infinity].

x → 7+, y → –[infinity]. is the correct option

The statement (C) as x approaches 7 from the left, y approaches -∞ describe the behavior of the graph of the function.

It is defined as a spceial type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a rational function:

[tex]\rm f(x) =\dfrac{-2x^2+14}{x^2-49}[/tex]

x² - 49 cannot be zero:

x² - 49 ≠ 0

x ≠ 7, x ≠  -7

From the graph, as x approaches 7 from the left, y approaches -∞

Thus, the statement (C) as x approaches 7 from the left, y approaches -∞ describe the behavior of the graph of the function.

You are splitting the equation up. (I don't really know how to explain it sorry)

The correct steps to evaluate 5 · 58 using the distributive property following are: 5(58) = 5(50 + 8) = 5 · 50 +5 · 8 = 250 + 40 = 290.

The product of a number by addition is equal to the total of the products of that number by each of the addends, according to the distribution property of multiplication.

The correct steps to evaluate 5 · 58 using the distributive property are:

Start with the expression 5 · 58.

Use the distributive property to rewrite the expression as 5(50 + 8).

Use the distributive property again to rewrite the expression as 5 · 50 + 5 · 8.

Calculate the value of each term in the resulting expression:

5 · 50 = 250 and 5 · 8 = 40.

Add the values of the two terms to get the final result:

250 + 40 = 290.

Therefore, the correct answer is D. 5(58) = 5(50 + 8) = 5 · 50 + 5 · 8 = 250 + 40 = 290.

Answer:

They make 4 approximately tons of oxygen each year.

Step-by-step explanation:

( 250lbs × 32 ) ÷ 2000 = 4t

250 pounds because each tree makes about 250 pounds of oxygen a year.

× 32 because there are 32 trees, so they'll make 32 times more oxygen than one tree.

÷ 2000 because before that everything was in pounds, and the question asks about tons. There are 2000 pounds in a ton, so you divide by 2000 to get the answer, which is 4 tons.
