Mr. Martin's car odometer showed 10,393 miles. His wife's odometer showed 26,481 miles. How many more miles were shown on his wife's odometer than on Mr. Martin's odometer?

Answers

Answer:

16,088 more miles

Step-by-step explanation:

Do  26,481-10,393 to get the answer.

26,481-10,393=16,088

The reason that you need to use subtraction to solve this problem is because the word problem says ”how many more”. I’ve learned in school that this is a sign that you have to find the difference to the terms being used in the problem, in this case, 26,481 and 10,393. To find the difference is to subtract the smaller number from the larger number, showing that you have to do 26,481-10,393 to get the answer.

Step-by-step explanation:

Since we already have the values of the variables and the equation, all we have to do is plug in the numbers.

-b + 3x

-(4) + 3(-5)

-4 + (-15)

-4 - 15

-19

Answer:

[tex]\boxed {\boxed {\sf -19}}[/tex]

Step-by-step explanation:

We are asked to evaluate the following expression.

[tex]-b+3x[/tex]

We know the b is equal to 4, and x is equal to -5.

b=4 x=-5

We can substitute the values into the expression.

[tex]-(4) + 3(-5)[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Multiply first. We multiply -1 and 4, then 3 and -5.

[tex][-1 *4] + 3(-5)[/tex]

[tex]-4+ [3*(-5)][/tex]

[tex]-4+-15[/tex]

Add.

[tex]-19[/tex]

The expression -b+3x is equal to -19 when b equals 4 and x equals -5.

Answers

Answer:

k=6

Step-by-step explanation:

Line partition formula

1/b(x2-x1)+x1, 1/b(y2-y1)+y1

Where b is the number partitions.

We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.

1/b(17-2)+2=7

1/b(15)=5

1/b=1/3

b=3

so the partition is 1/3

[tex] \frac{1}{3} (17 - 2) + 2 = 7[/tex]

So let find the y coordinate

[tex] \frac{1}{3} (8 - 5) + 5 = 6[/tex]

So our y coordinate is 6.

B. y2 = 8x2
C. x2 = 8y
D. y2 = 8x

Answers

If the vertex of the parabola is (0, 0) and the focus is (2, 0). Then the equation of the parabola is x² = 8y. Then the correct option is C.

What is the parabola?

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

The vertex of the parabola is (0, 0) and the focus is (2, 0).

Then the equation of the parabola passing through the origin is given as

x² = 4ay

Then the value a is equal to 2.

Then the equation will be

x² = 4 × 2 × y

x² = 8y

6i/9+2i

A. 81-18i/85
B. 2i/3
C. 6i/13
D. 12+54i/85

Answers

Answer:

D

Step-by-step explanation:

We want to simplify the expression:

[tex]\displaystyle \frac{6i}{9+2i}[/tex]

To do so, we can remove the imaginary unit in the denominator by multiply it by the conjugate.

The conjugate of a + bi is a - bi.

Hence, we will multiply the fraction by 9 - 2i:

[tex]\displaystyle =\frac{6i}{9+2i}\left(\frac{9-2i}{9-2i}\right)[/tex]

Multiply:

[tex]\displaystyle = \frac{6i(9-2i)}{(9+2i)(9-2i)}[/tex]

Difference of two squares:

[tex]\displaystyle = \frac{6i(9-2i)}{(9)^2 -(2i)^2}[/tex]

Simplify:

[tex]\displaystyle = \frac{54i-12i^2}{(81)-(4i^2)} = \frac{54i-(-12)}{81-(-4)} = \frac{12+54i}{85}[/tex]

Hence, our answer is D.

Martha has a French cookie recipe that calls for baking the cookies for 14 to 18 minutes at 180∘C. Her oven measures temperature in Fahrenheit only. At what temperature in degrees Fahrenheit should she set her oven to make the cookies per the recipe?

Answers

Answer:

180° Celsius is equal to approximately 356° Fahrenheit

Step-by-step explanation:

I hope this helps.

The value of 180 degree Celcius in Fahrenheit is 356.

What is unit conversion?

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Martha has a French cookie recipe that calls for baking the cookies for 14 to 18 minutes at 180∘C.

The temperature in Fahrenheit will be calculated as,

F = 1.8C + 32

F = ( 1.8 x 180 ) +32

F = 356

Therefore, the value of 180 degree Celcius in Fahrenheit is 356.

HELLO DEAR,

=> 10{(1 - cos²A)²} + 15cos⁴A = 6

=> 10{1 + cos⁴A - 2cos²A} + 15cos⁴A = 6

=> 10 + 10cos⁴A - 20cos²A + 15cos⁴A = 6

=> 25cos⁴A - 20cos²A + 4 = 0

=> 25cos⁴A - 10cos²A - 10cos²A + 4 = 0

=> 5cos²A(5cos²A - 2) - 2(5cos²A - 2) = 0

=> (5cos²A - 2)(5cos²A - 2) = 0

=> cos²A = 2/5

=> cosA = √2/√5 [ secA = √5/√2]

therefore,

sinA = √[1 - 2/5] = √3/√5 [ cosecA = √5/√3]

now,

27cosec^6A + 8sec^6A

=> 27 × {(√5/√3)²}³ + 8 × {(√5/√2)²}³
