what are the value of x in the equation x^2+4-1 =0
Answer:
x = ±sqrt(3) i
Step-by-step explanation:
x^2+4-1 =0
Combine like terms
x^2 +3 = 0
Subtract 3 from each side
x^2 +3-3 = 0-3
x^2 = -3
Take the square root of each side
sqrt(x^2) = sqrt(-3)
x = ±sqrt(3) sqrt(-1)
x = ±sqrt(3) i

what is the vertex of a parabola represented by the equation f(x) = -2 (x-4)^2 - 7
Answer:
f ( x ) = x ^2 + 1
f ( x ) = 7 x^ 2 + 5 x − 4
f ( x ) = 4 ( x − 3 ) ^2

Determine wether the lines are parallel perpendicular or neither
Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

1. Samuel is out with a kite. When he takes a break he attaches it to the floor. The kite is on a thread that is 16 meters long and makes a 30 degrees angle with the floor. How high above the floor is the kite?
Answer:
[tex]h=8m[/tex]
Step-by-step explanation:
From the question we are told that:
Slant height [tex]S=16meters[/tex]
Angle [tex]\theta =30[/tex]
Generally the equation for Height h is mathematically given by
[tex]h=Ssin\theta[/tex]
[tex]h=16*sin30[/tex]
[tex]h=8m[/tex]
y+1=3(x – 4)
2-intercept:
C
y-intercept:
Answer:
x-intercept is (13/3, 0)
y-intercept is (0,-13)
Step-by-step explanation:
change y+1 = 3(x-4) into slope-intercept form:
y+1 = 3x-12
y = 3x-13
y-intercept is (0,-13)
to get x-intercept, plug zero in for 'y' and solve for 'x':
0 = 3x-13
13 = 3x
13/3 = x
x-intercept is (13/3, 0)

Answer:
after 4 hours she cycled 48+ 20 which is 68 miles
Step-by-step explanation:
Answer:
So, d(4)=68. That means that after 4 hours, Joanna has cycled 68 miles.
Step-by-step explanation:
First, we need to find what d(4) equals. In this equation t=4, so to solve plugin 4 and simplify. Therefore, the equation is [tex]d(4)=12(4)+20[/tex]. Once you multiply and add you get d(4)=68; this answers the first question.
Then, the next two questions ask you to interpret this answer. To do that go back and read what each variable stands for. "t" is for the time Joanna has cycled. So, in the equation d(4), 4 hours have passed. Additionally, "d(4)" represents the number of miles she has ridden. This means since d(4)=68 she has cycled 68 miles.
Note that since I cannot see the options I guessed at the exact wording, but the answers should be similar to what I wrote.
fractions whose values are between 9/20 and 13/25
Answer:
10/25

The quotient of a number and - 2/3 is -9/10
What is the number?
1 7/20
3/5
29/30
20/27
Answer:
n = 3/5
Step-by-step explanation:
Represent this quotient as:
n
---------
-2/3
and set it equal to -9/10:
n -9
--------- = -------
-2/3 10
Cross multiplication yields:
10n = 6, so that n = 6/10 or n = 3/5
Find the area of the shaded region. Round to the nearest tenth.
Given: the radius of the circle is 5 inches.
Answer:
a = 21.5 in²
Step-by-step explanation:
Area of square
a = s²
a = 10²
a = 100
--------------------
Area of circle
a = πr²
a = π5²
a =π*25
a = 78.5398163397
-----------------------
Area shaded
a = square - circle
a = 100 - 78.5398163397
a = 21.4601836603
Rounded
a = 21.5 in²
