Answer:
2
Step-by-step explanation:
f(x)= 2x^5-3x^3+2x^2+1
Let x=1
f(1)= 2(1)^5-3(1)^3+2(1)^2+1
= 2*1 -3*1+2(1) +1
= 2-3+2+1

Answer:
-343p^3
Step-by-step explanation:
This is the answer because -7x-7x-7 would be -343 and you MUST keep the negative sign. The p x pxp would be p^3
Multiply the numbers:
-343p^3 would be your answer
Hope this helps!! :D
Answer:
1530cm
Step-by-step explanation:
First figure (9x10)x9=810
Second figure (18x10)x4=720
720+810=1530
Answer:
D
Step-by-step explanation:
Parallel lines have the same gradient.
A line with a slope of zero is a horizontal line. Although two lines that have a slope of zero will result in two parallel lines, not all parallel lines are horizontal lines. Since the question is asking for which statement <u>must</u> be true, option A is incorrect.
If the slopes of two lines are negative reciprocals, they are perpendicular to each other. This is because the product of the gradients of 2 perpendicular lines is -1. Let the gradient of the first line be A and the other be B.
AB= -1


Thus, option B is incorrect too.
Undefined slopes gives vertical lines. Like option A, if two lines have an undefined slope, they will be parallel to each other. However since parallel lines are nit necessarily vertical lines, option C is also incorrect.
Answer:
T = 1yrs and 8month
Step-by-step explanation:
S.I = $97.3O
S.I = PTR/100
$<u>97.30</u> = <u>$1200 × 4.5 × T</u>
1 100
Cross multiply
$5400T = $9730
divide both sides by$5400
T = 1.8yrs
