Answer:
Step-by-step explanation:
ax² + bx + c = 0
[tex]x_{1}[/tex] = [tex]\frac{-b - \sqrt{b^2 -4ac} }{2a}[/tex]
[tex]x_{2}[/tex] = [tex]\frac{-b+\sqrt{b^2 -4ac} }{2a}[/tex]
~~~~~~~~~~~~~~~~~~~
x² + 4x - 16 = 0
a = 1 , b = 4 , c = - 16
[tex]x_{1}[/tex] = ( - 4 - [tex]\sqrt{16+64}[/tex] ) ÷ 2 = - 2 - 4√5
[tex]x_{2}[/tex] = - 2 + 4√5

What is 34107.12 to the nearest half centimeters? 
Answer:
34107cm
Step-by-step explanation:
Find the area of the figure
Answer:
132cm^2
Step-by-step explanation:
to solve for the area of this we can split it into smaller shapes and sum the areas afterward-
the top rectangle has an area equal to Length x Width
4x7 = 28cm^2
the centre rectangle is done similarly-
7x8 = 56cm^2
lastly the two triangles which are solved with base x height divided by two
now since we know that the centre piece is 7cm across, and that the two side triangles are equal in size, that means that we know the base to be 19-7 divided by 2 which gives 6 each-
[tex]\frac{(6)(8)}{2}[/tex] (2) = (6)(8) = 48cm
now summing them we have 28 + 56 + 48 = 132cm^2

Which graph represents the parametric equations x(t) = t – 4 and y(t) = t2 + 5 for –1 ≤ t ≤ 2?
Which graph indeed?
Eliminate the parameter:
x = t - 4 ⇒ t = x + 4
⇒ y = t² + 5 = (x + 4)² + 5
which is the equation of a parabola with vertex at (-4, 5) and opening upwards, plotted with domain
-1 ≤ t ≤ 2 ⇒ -1 ≤ x + 4 ≤ 2 ⇒ -5 ≤ x ≤ -2

A) 520 ft3
B) 528 ft3
D) 548 ft3
C) 550 ft3
Answer:
B.
Step-by-step explanation:
1) the volume can be calculated as sum:
V=V₁+V₂;
2) V₁=6*8*8=384 [ft³];
3) V₂=0.5*6*6*8=144 [ft³];
4) the required volume:
V=384+144=528 [ft³]

What is the total length of border needed in feet and
inches?
Find the perimeter and area of the shaded region.
Answer:
1. 144 m; 2. 720m²;
Step-by-step explanation:
1.
First we need to know how much edges are of the figure. Since there is 12, we need to multiple the length of an edge to how many of them are:
12 • 12 = 144 m
2.
Since one edge is 12 m, first calculate the plot of a little square (as there are 5 in the pic):
12 • 12 = 144 m² (one square)
Now we know that one square's plot is 144 m².
Since there is 5 of them, we need to multiply the plot 5 times, since there are five mini squares:
144 • 5 = 720 m²
Now we know the plot of the full figure.

Probability which can be classified as an event
The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible. Converting the fraction 35 to a decimal, we would say there is a 0.6 probability of choosing a banana. This basic definition of probability assumes that all the outcomes are equally likely to occur.

Estimate the values for the two
missing quantities. Enter your
estimates into the blank boxes in
the table.
The first missing quantity is force due to gravity, and it is 215.1 N.
The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.
Force between two massesThe force between two masses is determined by applying Newton's law of universal gravitation as shown below;
[tex]F = \frac{GMm}{R^2}[/tex]
where;
M is mass of Earth = 5.97 x 10²⁴ kgm is mass of the satelliteR is the distance between the satellite and the EarthG is universal gravitation constantFirst missing quantityThe first missing quantity is force due to gravity, and it is calculated as follows;
[tex]F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N[/tex]
Second missing quantityThe second missing quantity is distance between the statellite and the Earth,
[tex]R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km[/tex]
