Answer:
9
Step-by-step explanation:
UT^2 = UV * UW
6^2 = (x - 7)(x - 7 + 5)
36 = (x - 7)(x - 2)
36 = x^2 - 2x - 7x + 14
x^2 - 9x - 22 = 0
(x - 11)(x + 2) = 0
x - 11 = 0 or x + 2 = 0
x = 11
UW = x - 7 + 5
UW = 11 - 7 + 5
UW = 9
The height is 3 feet long
you multiply 5 by 4 and get 20 and 20x3=60 therefore 3 is your answer
The quadratic function that models the data given in the table is 203.8x² - 26.6x + 8.6
<h3>What is the quadratic function?</h3>
A quadratic function is an equation that usually has a single variable and it is raised to the power of 2.
A quadratic function has the form : ax² + bx + c = 0
Where: a, b,c are known numbers and x is unknown
Given the quadratic function: 185x²+ 1.
- Number of views when 1 day has passed = 185(1) + 1 = 186
- Number of views when 6 days has passed = 185(6²) + 1 = 6661
Given the quadratic function: 203.8x² - 26.6x + 8.6
- Number of views when 1 day has passed = 203.8(1)² - 26.6(1)+ 8.6 = 185.80
- Number of views when 6 days has passed = 203.8(6)² - 26.6(6) + 8.6 = 7185.80

Answer:
first number= 19/5
second number= 2/5
Step-by-step explanation:
first number= a
second number= b
a+3b=5 equation 1
b+2a=8 equation 2
using equation 2 we have
b=8-2a
using equation 1 we have
a+3(8-2a)=5
a+24-6a=5
24-5=6a-a
19=5a
a=19/5 = first number
so using b=8-2a
we have
b=8-2(19/5)
b=8-(38/5)
b=2/5 = second number
