The measure of b is ____.
Answers
Answer:
[tex]\Huge\boxed{b=21}[/tex]
Step-by-step explanation:
Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
where a and b = legs and c = hypotenuse
we are given a leg and the hypotenuse so we plug in what we have into the formula
[tex]20^2+b^2=29^2[/tex]
now we solve for b
step 1 subtract 20^2 from each side
[tex]b^2=29^2-20^2\\29^2=841\\2-^2=400\\841-400=441\\441=b^2[/tex]
finally we want to get rid of the exponent on the b
to do so we take the square root of each side
[tex]\sqrt{441} =\sqrt{b^2} \\\sqrt{441} =21\\\sqrt{b^2} =b[/tex]
we're left with b = 21
Note: They Pythagorean theorem only works with right triangles

Answers
Answer:
20
Step-by-step explanation:
Given that:
Red flowers = 1/8
Purple = 1/4
(1/8 + 1/4) = (1 + 2) / 8 = 3/8
Fraction left :
1 - 3/8 =. 5/8
Pink flowers :
1/4 of fraction left ;
1/4 * 5/8 = 5/32
Number of pink flowers
Total number of flowers = 128
5/32 * 128
640 / 32
= 20
20 pink flowers

Prove that the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
Answers
The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
The equation is given as:
x^2 + (1 - k).x+k-3 = 0
For an equation to have real root, then the following must be true:
[tex]b^2 \ge 4ac[/tex]
In x^2 + (1 - k).x+k-3 = 0, we have:
a = 1
b = 1 - k
c = k - 3
So, we have:
[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]
Evaluate
[tex]1 - 2k + k^2 \ge 4k - 12[/tex]
Collect like terms
[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]
[tex]k^2 - 6k + 13 \ge 0[/tex]
Using a graphing calculator, the value of k is all real numbers
Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
