Use Pythagorean therom which is
A^2+B^2=C^2
C is the slant (65mi)
A is the vertical line (25mi)
solving for B so the equation is
C^2-A^2=B^2
4225-625=3600
√(3600)= 60
She can save 60miles
2. B(-5,6)
3. C’(3,7)
4. C’D’
5. angle D’
6. Reflected over the y axis
Answer:
Step-by-step explanation:
n is perpendicular. - 1/(2/5) = - 5/2. n is the negative reciprocal of the given line.
m is neither.
p is parallel to the given line. For example y = 2/5x
and y = 2/5 x + 9 are parallel to each other.
Answer:
159
Step-by-step explanation:
To evaluate f(g(- 5)), first evaluate g(- 5) then substitute this value into f(x)
g(- 5) = 2(- 5)² + 7 = 50 + 7 = 57
f(57) = (3 × 57) - 12 = 171 - 12 = 159
