Answer:
29.5 feet
Step-by-step explanation:
A firefighter extends a ladder against the side of a house. The ladder makes a 32°\degree° angle with the ground. The base of the ladder is 25 feet from the house. Find how high the ladder reaches up the side of the house to the nearest tenth of a foot.
We solve using Trigonometric function of Cosine
= cos theta = Adjacent/Hypotenuse
Theta = 32°
Adjacent = 25 feet
Hypotenuse = Height of the ladder
= cos 32 = 25/x
x = 25/cos 32
x = 29.479460084 feet
Approximately= 29.5 feet
Answer:
4 meters
Step-by-step explanation:
Given a quadratic equation in which the coefficient of is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.
Since the divers height, y is modeled by the equation
Step 1: Determine the equation of symmetry
In the equation above, a=-1, b=2, c=3
Equation of symmetry,
Step 2: Find the value of y at the point of symmetry
That is, we substitute x obtained above into the y and solve.
The maximum height of the diver is therefore 4 meters.
Answer:
C.
Step-by-step explanation:
Let x be the total monthly sales.
We have been given that a salesperson earns a salary of $700 per month plus 2% of the sales. The salesperson want to have a monthly income of at least $1800.
This means that 700 plus 2% of total monthly sales should be greater than or equal to 1800. We can represent this information in an equation as:
Let us solve our inequality to find the monthly sales (x).
Subtract 700 from both sides of our inequality.
Divide both sides of inequality by 0.02.
Therefore, the total monthly sales must be greater than or equal to 55,000 and option C is the correct choice.
Answer:
4, 2
Step-by-step explanation:
The formulas for 180 clockwise and counterclockwise wise is -x,-y since both of them are negative they would become positive because -x * -x = + same with y.
