(-3/10) (-5/12) you have to multiply

Mathematics

Answer:

1/8

Step-by-step explanation:

Multiply the two numerators to get the product numerator

-3 X -5 = 15

Multiply the two denominators to get the product denominator

10 X 12 = 120

(-3/10) (-5/12)

=15/120

Reduce the fraction by dividing top and bottom by 15.

15/15 = 1

120/15=8

The answer is 1/8.

Answer:

1/8

<h3>Step by Step Instructions</h3>
  1. \frac{ - 3}{10}  \times  \frac{ - 5}{12}
  2. \frac{ - 3}{10}  \times  \frac{ - 5}{12}  =  \frac{15}{120}
  3. \frac{15}{120} = \frac{1}{8}
  4. \frac{1}{8}
<h3>Notes:</h3>
  • Because both fractions are negative, your answer is a positive.
  • To multiply fractions, multiply the numerators and denominators

Help me determine if this function is even or odd!
11Alexandr11 [23.1K]
If u end up with the exact same function that you started with (that is, if f (−x) = f (x), so all of the signs are the same), then the function is even if u end up with the exact opposite of what you started with (that is, if f (−x) = −f (x), so all of the signs are switched) then the function is odd

Answer pls question in the picture
MAXImum [283]
Hi !

I’m sorry I won’t be doing the solving for you because it should be easy but I will give you the logic in case you don’t know how to solve them...

Please look at the picture below

According to the theorem we know that DE is:

DE = 1/2 ( BC)

Solve for X then find the values.

Note: remember that if you want to make your life easy multiply both side by 2 to get rid of the 1/2.

(3) Last Sunday 1,675 people visited the amusement park. 56% of the visitors were adults, 16% were teenagers, and 28% were child
ELEN [110]

Answer:

adults= 938, teens = 268, children= 469

Step-by-step explanation:

line up your givens like this:

1,675 visitors = 100%

? adults = 56%

? teenagers = 16%

? children = 28%

cross-multiply

adults*100 = 1,675*56

teens*100 = 1,675*16

children*100 = 1,675*28

divide each side by 100

adults= 1,675*56/100

teens = 1,675*16/100

children= 1,675*28/100

solve

adults= 938, teens = 268, children= 469

Hope this helps!

2. Factor f(x) = x4 + 10x3 + 35x2 + 50x + 24 completely showing all work and steps with synthetic division. Then sketch the grap
telo118 [61]

We need to use rational root theorem to find out roots here.

The rational root theorem states that if p(x) is a polynomial with integer coefficients and if \frac{p}{q} is a zero of p(x) then p is a factor of constant term and q is a factor of leasing term coefficient.

Here factors of constant term are 1,2,3,4,6,8,12,24,-1,-2,-3,-4,-6,-8,-12, and -24.

And factors of leading coefficient is -1,1.

Hence possible roots may be -1,1,-2,2,-3,3,-4,4,-6,6,-8,8,-12,12,-24 and 24.

Let us plugin these in f(x) to find zeroes.

f(-1)=(-1)^{4}+10(-1)^{3}+35(-1)^{2}+50(-1)+24 =1-10+35-50+24=0

Hence x=-1 is a zero which means x-(-1)=x+1 is a factor.

Let us use synthetic division to find quotient.

-1 | 1  10  35  50  24

  <u>| 0  -1  -9  -26   -24</u>

   <u> 1    9  26  24    0</u>

Hence quotient is x^{3} +9x^{2} +26x+24

Since all coefficients are positive, root must be negative. Let's plugin all remaining negative numbers in the quotient.

(-2)^{3}+9(-2)^{2}+26(-2)+24 = 0

Hence x+2 is another factor.

Let us find quotient again using synthetic division.

-2 | 1   9  26   24

   <u>| 0  -2  -14   -24</u>

   <u>  1    7    12     0</u>

Hence quotient is x^{2} +7x+12

Again we got quotient with all positive coefficients, let us plugin remaining negative numbers from rational root theorem.

(-3)^{2}+7(-3)+12=-9-21+12=0

Hence x+3 is also a factor.

Let us find quotient using synthetic division.

-3 | 1  7  12

   <u>| 0 -3  -12</u>

    <u> 1    4    0</u>

Hence quotient is x+4.

So, f(x)=x^{4}+10x^{3}+35x^{2}+50x+24 =(x+1)(x+2)(x+3)(x+4)

Please have a look at the graph attached.
