Given two vectors a⃗ = 4.60 i^+ 7.20 j^ and b⃗ = 5.10 i^− 2.70 j^ , find the scalar product of the two vectors a⃗ and b⃗ .

grin007 [14]

A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9

If f(x)=2x-1+3 and g(x)=5x-9, what is (f-g)(x)?

dangina [55]

Answer:

$\large\boxed{(f-g)(x)=-3x+11}$

Step-by-step explanation:

$(f-g)(x)=f(x)-g(x)\\\\f(x)=2x-1+3=2x+2\\g(x)=5x-9\\\\\text{Substitute:}\\\\(f-g)(x)=(2x+2)-(5x-9)\\\\=2x+2-5x-(-9)\\\\=2x+2-5x+9\qquad\text{combine like terms}\\\\=(2x-5x)+(2+9)\\\\=-3x+11$

in an election 32 thousand people voted for mayor Jackson. A total of 56 thousand people voted in the election. what is the rati

Alenkinab [10]

<span>Let us first find out how many votes were not for mayor Jackson. We get the answer by subtracting the votes for mayor Jackson from the total number of votes. Total votes = 56,000 less votes for mayor Jackson = 32,000 Votes not for mayor Jackson = 24,000 The ratio of number of votes not for mayor Jackson to the total number of votes: 24,000 : 56,000 (both the numbers are divisible by 8000 which is a common factor) So the ratio in its lowest for is 3 : 7</span>
