Answer:
Annabelle is correct.
Step-by-step explanation:
1. When multiplying two numbers with exponents, the exponents are always added and not multiplied. However, when there is an number with an exponent that has an exponent (for example (5^2)^3) you would multiply them.
2. Applying this to your question would make Annabelle's work correct and Navene's work incorrect.
Hope you understood!
Answer:
See attachment
Step-by-step explanation:
The given parametric equations are;
and
,
.
We can graph this by plotting some few points within the given range or eliminate the parameter to identify the type of curve.
Plotting points;
When
,
and 
This gives the point (-4,3).
When 
and 
This gives the point (0,5).
When 
and 
This gives the point (6,8).
We plot these points and draw a straight line through them.
Eliminating the parameter.


Make t the subject in the second equation;

Substitute into the first equation;

This implies that;


This is an equation of a straight line with slope
and y-intercept 5 on the interval

So, for no.6 I got 1/16 or 0.0625 but I don’t know which one it is out if the ones you have?
and then for no.7 I got 9/4 which is 2.25? Which then isn’t any of the answers that there is to choose from.
sorry to be no help. But that’s what I got :(
Answer:
∠EFG=(3× 11.2+17)º = 50.6°
∠LMN= (12×11.2−5)º = 129.4°
Step-by-step explanation:
We know that if two angles are supplementary two each other sum of these two angles is equal to 180°.
It is given that ∠EFG and ∠LMN are supplementary angles.
Therefore, ∠EFG +∠LMN = 180°
Given that: ∠EFG=(3x+17)º and ∠LMN=(12x−5)º
⇒ (3x+17)º + (12x−5)º =180°
⇒ (15x+12)° = 180°
⇒15x = 168°
⇒ x = 168°/15
x = 11.2°
Then, ∠EFG=(3× 11.2+17)º = 50.6°
Also, ∠LMN= (12×11.2−5)º = 129.4°
