Step-by-step explanation:
Given two expressions:
and
a. When
then
and
b. When
then
and
c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
I think the last one. Sorry if I’m wrong. Minus year 2 and 5
Answer:
×=30⁰ :)
Step-by-step explanation:
x⁰+(x+30⁰)= 90⁰
x⁰+x⁰= 90⁰-30⁰=60⁰
2x⁰=60⁰
60⁰÷2=30⁰ => x⁰=30⁰
verification:
30⁰+(30⁰+30⁰)=90⁰
Answer:
The Facility cost for each spark plug is $1.4.
Step-by-step explanation:
Given:
Mark up cost = 25%
Charges for each spark plugs for customers = $1.75
We need to find the cost of each spark plug for the facility.
Solution:
Let the Facility cost of each spark plug be 'x'.
So we can say that;
Markup cost =
So we can say that;
Facility cost of each spark plus the Markup cost is equal to cost facilty charges for customer.
framing in equation form we get;
Dividing both side by 1.25 we get;
Hence the Facility cost for each spark plug is $1.4.

Step-by-step explanation:
1. Plot the point (5,-2). This point lies in the fourth quadrant.
2. Draw a line from the origin to the point and trace to the axes to form a right triangle.
3. Use Pythagoras Theorem to find the hypotenuse.
4. Use the mnemonics SOH CAH TOA to find the values of sine, cosine and tangent of the angle respectively and then find the reciprocals, co-secant,secant and cotangent.
NB: In the fourth quadrant, only the cosine and its reciprocal are positive.
