Answer:
65.1 km/hr
Step-by-step explanation:
The car travelled 217km in 3 hours and 20 minutes. We can divide the km by the time to obtain a speed that is km per a time value. If we would like it expressed as km/hour, we will need to convert the 20 minutes into hours.
20 minutes is (20 minutes)*(1 hour/60 minutes) = (1/3) hour
The total time to travel 217km is 3 and 1/3, or (10/3) hours.
The speed is (217 km/((10/3) hours)
Speed = 65.1 km/hr
Answer:
Step-by-step explanation:
To find the quadratic equation when the roots are given , we will use the formula:
sum of roots + product of roots = 0
sum of roots = -6 + 2 = -4
product of roots = -6(2) = -12
substituting into the formula, we have
Parallel lines has equal slopes, so a line parallel to y = 1/2x + 6 will have a slope of 1/2.
The equation of a line passing through a point (x1, y1) with a slope, m, is given by: y - y1 = m(x - x1)
y - 2 = 1/2(x - 0)
y = 1/2x + 2
Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.
The theorem that can be used to prove that both right triangles are congruent is: A. LL
<h3>What is the Leg-leg Congruence Theorem (LL)?</h3>
The LL congruence theorem states that if two legs of one right triangle are congruent to two corresponding legs of another right triangle, then both right triangles are congruent triangles.
From the image given, both triangles have the following:
Two pairs of congruent legs - GM ≅ EO and MO ≅ OM
Therefore, the theorem that can be used to prove that both right triangles are congruent is: A. LL
