Answer:
$63
Step-by-step explanation:
First, we find the percentage that he saves:
9 is 3/5 of 15 which is 60%, 9 is 60% of 15 which means he save 60% of the money that he earns so,
60% of 105 = 63
This means he saved $65 from the money he earned.
Hope this helps!
Answer:
50°
Step-by-step explanation:
θ is located in between the hypotenuse and an adjacent side. So, we can use cosine to find the measure of θ, as cosine is equal to adjacent/hypotense. 16/25 = 0.64, which is listed as the cosine of 50°, so the angle is 50°.
Hope this helps! :)
The required equation of the hyperbola is expressed as
The standard form for calculating the equation of a parabola along the x-axis is expressed as:
where:
(h, k) is the center
(k±c, h) are the foci
is the directrix
From the question given, we can see that foci = (±5, 0)
k±c, h = ±5, 0
k = 0
h = 0
c = 5
From the directrix,
Also, we need to know that;
a²+b² = c²
10 + b² = 5²
b² = 25 - 10
b² = 15
Substituting the gotten values into the equation of a hyperbola;
This gives the required equation of the hyperbola
