draw the tree, the person and the shadows - notice the similar triangles
the following proportion counts
x : 5 = 130 : 10
x = (5*130)/10
x = 65 feet
y = x ^2+ 8x + 15 what is the vertex, axis of symmetry, and y-intercept? Pleaseee help
Answer:
Step-by-step explanation:
y = x^2 + 8x + 15
= x^2 + 8x + 4^2 - 4^2 + 15
= (x+4)^2-1
Answer:
(−4, −1)
vertex, axis of symmetry, and y-intercept: y = (x + 4)² −1

b)4
c)6
Step-by-step explanation:
Simplify the expression
Hi there!
So what we need to do here is this...
Multiply -3/4 with there own parentheses and multiply 2 with it’s own parentthese also.
[tex]- \frac{3}{4} x 5p = 3 \frac{3}{4} p[/tex]
[tex]-\frac{3}{4} x 12 = 9[/tex]
Then do the second parenthese...
[tex]2x8=16[/tex]
[tex]2x - \frac{1}{4} = \frac{1}{2}p[/tex]
Add them like this...
[tex]( 3 \frac{3}{4}p + 9 ) + ( 16 -\frac{1}{2}p )[/tex]
Simplflied it again.../ since 3 3/4 and 1/2 both have p, add them...
[tex]3 \frac{3}{4} + - \frac{1}{2}p=3 \frac{1}{4}p[/tex]
Add the rest:
[tex]3 \frac{1}{4}p+9+16[/tex]

How would 125% be expressed as a decimal. You also need to explain what is the rule in changing Percent to decimal . Give another 3 examples . pa help po ty po in advance ❤
Answer:
[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]
[tex]\frac{10}{100} = 10%[/tex]
Step-by-step explanation:
125 % can be expressed as decimal as
[tex]\frac{125}{100} \\\frac{25}{20} \\\frac{5}{4}[/tex]
Rule in changing Percent to decimal
a) Divide a percent by 100
b) Remove percent sign
example
30%
= 3/10
45 %
[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]
[tex]\frac{10}{100} = 10%[/tex]

Is it possible to construct Triangle ABC with angles 40, 60 and 90 degrees?
EXPLAIN WHY OR WHY NOT
Answer:
No, it's not possible
Step-by-step explanation:
A triangle must equal 180 degrees. 40+60+90 is 190, which is over 180.
Please Help This is due at midnight please and thank you
Answer:
Measure of angle s:
Sum all angles of triangle is = 180 degrees
So,
31 + 58 + x = 180
x = 180 - 31 - 58
x = 91
Measure of angle s: 91 degrees

solve for x. 9 4 13.5 x+4
Answer:
x = 2
Step-by-step explanation:
The parallel lines divide the transversals into proportional segments, that is
[tex]\frac{x+4}{13.5}[/tex] = [tex]\frac{4}{9}[/tex] ( cross- multiply )
9(x + 4) = 54 ( divide both sides by 9 )
x + 4 = 6 ( subtract 4 from both sides )
x = 2

What is the value ofx?
Answer:
x = 39
Step-by-step explanation:
∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.
2x - 14 + 26 = 90
2x + 12 = 90
2x = 78
x = 39

Please help!! Use the discriminate to determine the number of solutions and types of solutions for the quadratic equation.
Discriminant=__
Number of solutions for the quadratic equation=___
a^2+3a=7
Answer:
two unequal, complex roots
Step-by-step explanation:
Rewrite this quadratic as a^2 + 3a - 7 = 0. The coefficients are {1, 3, -7}. The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.
Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.
