I need more information to solve this.
Step-by-step explanation:
Standard form is a formula: if I remember correctly, it is Ax+By=C
I hope I helped somehow!
Answer:
Step-by-step explanation:
Use the Law of Cosines
A = arccos[(10²+14²-9.6²)/(2×10×14) ≅ 43.3°
Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
Answer:
45 girls
Step-by-step explanation:
since the ratio is 3:5, 3 being the boys, we can divide 27 by 3. We get nine, which is the number we multiply 5 with. 9*5=45 girls
Answer:

Step-by-step explanation:
Vertex form of the quadratic equation: 
where the vertex is 
Given vertex = (6, 5):

If one the x-intercepts is (8, 0):




Therefore, equation of parabola:

x-intercepts occur when f(x) = 0:






Therefore, the x-coordinate of the other x-intercept is 4.
