Answer:
(5) The perpendicular height of the triangle is 8.48 mm.
(6) The 1184.86 cm far up the wall the ladder reach.
Step-by-step explanation:
Part (5):
When a perpendicular is drawn in an isosceles triangle then the perpendicular divided the base into 2 equal parts.
The figures is shown below.
In ΔABC,
CB = 6 mm
So,
CD = BD = 3 mm
Now calculating the perpendicular height of the triangle.
Using Pythagoras theorem in ΔADC:
Thus, the perpendicular height of the triangle is 8.48 mm.
Part (6):
The figure is shown below.
Converting meter to centimeter:
1 m = 100 cm
So,
12 m = 1200 cm
Using Pythagoras theorem in ΔXYZ:
Thus, 1184.86 cm far up the wall the ladder reach.
You left off the choices but we don't need them.
The point slope form, a line with slope m through (a,b), is
y - b = m(x-a)
We have m=1.8 and (a,b)=(-4.5,1.4) so
Answer: y - 1.4 = 1.8(x + 4.5)
You'll have to find that one among the choices yourself.
We solve for y to get the slope intercept form
y = mx + (b - ma)
Here we have m=1.8 and (a,b)=(-4.5,1.4) so
y = 1.8x + (1.4 - 1.8(-4.5))
y = 1.8x + 9.5
Answer:
f(3) = -11
Step-by-step explanation:
f(3) means you sub the value that is inside into x
f(3) = -3(3) - 2
= -9 - 2
= -11
When someone dies everyone wonders what will happen to all of their possessions. If the person had a will then everyone will know what they have to keep. If the person did not have a will then no one will know what to keep and what not to keep. That can cause problems among family and friends. To keep the peace and sentimental value in balance a will is very important to make.
