Answer:2x squared + 9x +4

Step-by-step explanation:you would multiply the 2x by everything in the second set of parenthesis and the multiply the 1 to everything in the other set of parenthesis.

There are 2 x’s so it’s 2x^2 + 9x because 2x4 is 8 + 1 x and then + 4 because you connect like terms so it would be 2x^2+9x+4

Do a and b have the same value in the equations 2(a-1.1)=5.8 and 5/2b-2 3/4=7 1/4

luda_lava [24]

Answer:

Step-by-step explanation:

Solve each equation and compare the solutions

2(a - 1.1) = 5.8
a - 1.1 = 5.8/2
a - 1.1 = 2.9
a = 2.9 + 1.1
a = 4

(5/2)b - 2 3/4 = 7 1/4
2.5b = 7 1/4 + 2 3/4
2.5b = 10
b = 10/2.5
b = 4

Both a and b have same value

Calculate a vector c in the same direction of the vector a and that has the same length as the vector b

Viktor [21]

For any scalar $t>0$ , $t\vec a$ is a vector pointing in the same direction as $a$ .

To force this vector to have the same length as another vector $\vec b$ , first normalize $t\vec a$ by dividing it by its norm,

$\dfrac{t\vec a}{\|t\vec a\|}=\dfrac{t\vec a}{t\|\vec a\|}=\dfrac{\vec a}{\|\vec a\|}$

then multiply this vector by the norm of $\vec b$ , so that

$\vec c=\dfrac{\|\vec b\|}{\|\vec a\|}\vec a$

To confirm that $\vec c$ has the same length as $\vec b$ :

$\|\vec c\|=\left\|\dfrac{\|\vec b\|}{\|\vec a\|}\vec a\right\|=\dfrac{\|\vec b\|}{\|\vec a\|}\|\vec a\|=\|\vec b\|$
