Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

how do you find the axis of symmetry?
Answers
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

Convert each radian measure into degrees.
4) 8pi/3
Answers
Answer:
[tex]\boxed {\boxed {\sf 480\textdegree}}[/tex]
Step-by-step explanation:
First, remember that π radians is equal to 180 degrees. Therefore, to convert from radians to degrees, multiply by 180/π.
The radian measure given is 8π/3
[tex]\frac {8 \pi}{3} * \frac{180}{\pi}[/tex]
Multiply the fractions. Multiply across the numerator, then across the denominator.
[tex]\frac{8 \pi *180}{3 * \pi}[/tex]
The pi in the numerator and denominator will cancel out.
[tex]\frac{8 *180}{3 }[/tex]
Multiply.
[tex]\frac{1440}{3}=480[/tex]
The radian measure 8π/3 is equal to 480 degrees.

What is the Pythagorean theorem?Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
We have,
Hypotenuse = 137 feet
One side length:
Horizontal length = 105 feet
Another side length = side = length of the sand dune.
Using the Pythagorean theorem we get,
137² = side² + 105²
18769 = side² + 11025
side² = 7744
side = √7744
side = 88 feet
Thus,
The length of the sand dune is 88 feet.

A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.
Answers
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Answer:
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48Step-by-step explanation:
Let the larger number be = xLet the smaller number be = yAs the larger number is twelve more than a smaller, so
x = y + 12
As the sum of larger and smaller numbers is 84, so
x + y = 84
now substituting x = y + 12 in th equation x + y = 84
x + y = 84
(y + 12) + y = 84
2y + 12 = 84
subtract 12 from both sides
2y + 12 - 12 = 84 - 12
2y = 72
divide both sides by 2
2y/2 = 72/2
y = 36
Thus,
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48A computer repair company charges an initial fee plus $40 per hour for repair work. The total cost

Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.
Answers
Answer:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Step-by-step explanation:
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39

Answers
Answer:
the answer would be 160H
The cost of a job that lasts 1.5 hours is $ 192.5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The charge of each job by the plumbing company = $ 95
The charge on each hour for each job = $ 65
The equation for the cost of a job is = 65h + 95
where h is the number of hours for the job
Now , to calculate the cost of job that lasts 1.5 hours ,
substitute the value of h as 1.5
And , the equation becomes
= 65h + 95
= 65 ( 1.5 ) + 95
= 97.5 + 95
= $ 192.5
Hence , the cost of a job that lasts 1.5 hours is $ 192.5
