In the diagram below, find the value of y.

Answers

Answer 1

Answer:

y=130

Step-by-step explanation:

1) combine all like terms for the inside angles of the triangle

(3x-19) + (4x+8) + (x+7)3x-19+4x+8+x+78x-4

2) because the sum of all angles = 180 add that to the sum of all like terms

8x-4=180add 4 on both sides and divide both sides by 8this should be x=23

3) now you replace the x's with 23

(3(23) -19)69-1950

4) now we know that (3x-19)=50

5) take 180 and subtract 50

this is because y and (3x-19) creates a supplementary angle which also equals 180

6) 180-50=130

Lucy invested $19,000 in an account paying an interest rate of 3% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 8 years?

Answers

Answer: 24100

Step-by-step explanation:

The money in the account after 8 years is $24068.631.

Given that, principal=$19000 and the rate of interest=3%.

What is the formula to find the compound interest?

The formula to find the compound interest is CI=A-P.

Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.

Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]

=19000[tex](1.03)^{8}[/tex]

=19000×1.26677008139

=$24068.6315464

=$24068.631

Therefore, the money in account is $24068.631.

9. ∠DEF and ∠FEG are complementary. m∠DEF = (3x − 4)°, and m∠FEG = (5x + 6)°.
Find the measures of both angles.

Answers

Answer:

29°61°

Step-by-step explanation:

Complementary angles are two angles that add up to be 90 degrees.

We can write an equation and solve for x.

(3x - 4) + (5x + 6) = 90

~Combine like terms

8x + 2 = 90

~Subtract 2 to both sides

8x = 88

~Divide 8 to both sides

x = 11

Angle DEF:

3x − 4

3(11) - 4

33 - 4

29°

Angle FEG:

5x + 6

5(11) + 6

55 + 6

61°

Check:

29 + 61 = 90°

Which sequence of steps is a correct derivation of the difference quotient for f(x) = 3 – log x?

Answers

Answer:

Step-by-step explanation:

Where are the answer choices?

Still, it's possible to help you without your having shared those choices.

The "difference quotient" is defined as:

f(x + h) - f(x)

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

where h represents an incremental (small) change in x.

Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).

Therefore the difference quotient is:

{3 - log (x + h)} - {3 - log x}

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

This can be simplified. In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x

and the difference quotient is

-log ( x + h) + log x

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

This can be rewritten as

log x - log (x + h) x x

--------------------------- , or (1/h)*log ------------ , or (1/h) log { ----------- }

h (x + h) x + h

Answer:

47.67 miles (in 40.86 minutes or 40 minutes and 51.6 seconds)

Step-by-step explanation:

Simple. Multiply these values together to cancel out the quantity in the denominator (cross multiply).

0.681 * 70 = 47.67

let x be the distance in miles:

70.0/1 = x/0.681

0.681 * 70 = 1 * x

47.67 = 1 * x

47.67 = x

Answer:

The expression are

[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]

and

[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]

Step-by-step explanation:

Generally from the diagram the energy change from state A to state B is

[tex].\ \ \Delta E_2 \ \ \ \ \ \ \ \ \Delta E_2 \\A \ \ \to \ \ \ C \ \ \ \to \ \ \ B\\[/tex]

Also

[tex].\ \ \Delta E_3 \ \ \ \ \ \ \ \ \Delta E_4 \\A \ \ \to \ \ \ D \ \ \ \to \ \ \ B\\[/tex]

So two expressions for the difference in internal energy between state a and state b are

[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]

and

[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]
