Mathematics

larisa86 [58]3 years ago
4 0

Answer:

f(-14)=-15

Step-by-step explanation:

What ever is in the parentheses after the letter (in this case it's f) will be the x value since f(x).

So

f(-4)=5(-4)+5

Then solve.

f(-4)=-20+5

f(-4)=-15

-15

If x= 14 units y=8units and h =6 units what is the area of the trapezoid shown above
11111nata11111 [884]

Here's an answer, with some big 'IF's attached.  We can't be
sure of anything, because you never shared the picture of it
that was 'shown above'.

The area of a trapezoid is (1/2) (height) (base-1 + base-2).

Now, <u>IF</u> 'x' is one of the bases, and <u>IF</u> 'y' is the other one,
and <u>IF</u> 'h' is the height of the trapezoid, then

 Area = (1/2) (6) (14 + 8)

         =      (3)      (22)  =  <em>66 square units</em>.

But if any of them is not, then it isn't.

A demand loan for $8,944.61 with interest at 7.8% compounded semi-annually is repaid after two years, seven months. What is the
disa [49]

Answer:

the correct answer is option D which is $1,954.94

Step-by-step explanation:

loan amount =  $8,944.61

interest =  7.8% = 7.8 %/2 = 3.9 %

compounded semi annually =  2 × 12 + 7 = 31 months

                         time = 31/6 months

I =P(1+\dfrac{r}{100})^{\frac{31}{6}}-P\\ \\I =  8994.61(1+\dfrac{3.9}{100})^{\frac{31}{6}}-8994.61 \\I =1954.94

hence, the correct answer is option D which is $1,954.94

Y varies directly with x it has a constant rate of change of 6. When the value of y is 11, then the value of x could be?
makvit [3.9K]

Answer: \frac{11}{6}

<u>Explanation:</u>

y varies directly with x means: \frac{y}{x} = k  ; where k is the rate

  • \frac{y}{x} = k
  • \frac{11}{x} = 6
  • (x)\frac{11}{x} = 6(x)
  • 11 = 6x
  • \frac{11}{6} =\frac{6x}{6}
  • \frac{11}{6} = x
