Given the vectors u= <2, 1> and v= <5, 4>, determine the components of a vector represented by 2u - 3v

kati45 [8]

Answer:

C.) <-11, -10>

Step-by-step explanation:

Let's define how to work with vectors.

For two vectors:

V = <a, b>

W = <c, d>

The product of a scalar k and a vector is given by:

k*V = k*<a, b> = <k*a, k*b>

And the sum (or difference) of two vectors is given by:

V ± W = <a, b> ± <c, d> = <a ± c, b ± d>

Now that we know this, we can solve the problem.

Here we have the vectors:

u = <2, 1>

v = <5, 4>

then:

2u - 3*v = 2*<2, 1> - 3*<5, 4>

= <2*2, 2*1> - <3*5, 3*4>

= <4, 2> - <15, 12>

= <4 - 15, 2 - 12>

= < -11, -10>

Then the correct option is C.

Evaluate. Write your answer as an integer or as a decimal rounded to the nearest hundredth. tan 32° = _____

Advocard [28]

Answer

0.63

Explanation:

Given the expression

tan 32

Using Calculator

tan 32 = 0.6248

Converting to nearest hunderdth

tan 32 = 0.63

hence tan 32 to the nearest hunderdth is 0.63

Evaluate each expression (image provided). A.) 5 B.) 7 C.) 4 D.) 6

Mkey [24]

<h3>The answer is option A.</h3>

Step-by-step explanation:

$log_{3}(243)$

Can be written as

$log_{3}( {3}^{5} )$

Which is the same as

$5 log_{3}(3)$

But

$log_{3}(3) = 1$

So we have

5(1) = 5

On a certain hot summer's day, 225 people used the public swimming pool. The daily prices are $1.75 for children and $2.00 for

NikAS [45]

Answer:

Step-by-step explanation:

Let us represent:

Number of children = x = 59

Number of Adults = y = 166

On a certain hot summer's day, 225 people used the public swimming pool.

x + y = 225

x = 225 - y

The daily prices are $1.75 for children and $2.00 for adults. The receipts for admission totaled $435.25.

$1.75 × x + $2.00 × y = $435.25

1.75x + 2y = 435.25

We substitute 225 - y for x

Hence:

1.75(225 - y ) + 2y = 435.25

393.75 - 1.75y + 2y = 435.25

Collect like terms

-1.75y + 2y = 435.25 - 393.75

0.25y = 41.5

y = 41.5/0.25

y = 166 Adults

Note that:

x = 225 - y

x = 225 - 166

x = 59 children

Hence, the number of children is 59 and the number of Adults is 166
