Answer:
x=1 and -3
Step-by-step explanation:
log(x)+log(x+2)=log(3)
log(x(x+2))=log(3)
x(x+2)=3, simple quadratic. x=-3 and 1. Answered by Gauthmath
A is the right answer 3+5 is 8 plus 2 is 10. 2+3 is 5 plus 5 is 10
Answer:
∠ XAZ = 50°
Step-by-step explanation:
The measure of the circle = 360°
Given arc XYZ = 230°, then
arc XZ = 360° - 230° = 130°
The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is
∠ XAZ = 
(230 - 130)° = 0.5 × 100° = 50°
<span>This is correct. Data visualisation is done through the creation of graphs, which are simply visual representations of data that show relationships between variables. Bar graphs are a particular type of graph. Others include scatter graphs, line graphs and pie charts.</span>
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
