-40x = 16x2 + 38
Need the steps to solve this please
Answer:
-1.25 ± 0.90i correct to the nearest hundredth
Step-by-step explanation:
-40x = 16x2 + 38
16x^2 + 40x + 38 = 0 Simplify by dividing by 2:
8x^2 + 20x + 19 = 0
Using the quadratic formula:
x = [ -b ±√(b^2 - 4ac) ] / 2a
Plug in the coefficients of our equation:
x = [ -20 ±√(20^2 - 4*8*19) ] / 2*8
= -5/4 ± √(-208)/16
= -5/4 ± 14.4222i/16
= -1.25 ± 0.90i correct to the nearest hundredth.

g(x)=-|x| ; find g(-4)
Answer:
-4
Step-by-step explanation:
Plug in -4 for x, so the absolute value of -4 is 4. However, there's a minus sign out in front still, so it gets tacked on to the 4. So, g(-4)=-4
Reflect the point (2, -4) over y = x to become... a) (-4, 2) b) (-2, 4) c) (-2, -4) d) (2, 4)

A diver is 50 ft below sea level. Which integer correctly represents the situation?
Answer:
50 feet below sea level. First, look for keywords. The word “below” means you will need to use a negative integer. The answer is -50.
Step-by-step explanation:
hope this helps...
(─‿─)
Negative integers are used to represent values below zero, and in this context, "-50" represents a depth of 50 feet below the sea level.
In the context of sea level and vertical position, we often use positive and negative numbers to represent positions above or below a reference point, which is usually considered to be sea level.
When we say the diver is 50 feet below sea level, it means the diver is at a depth of 50 feet under the surface of the sea. In this case, we use negative numbers to represent positions below sea level.
So, if we consider sea level as the reference point (zero level), the number line extends in both positive and negative directions. Positive numbers represent positions above sea level, and negative numbers represent positions below sea level.
Since the diver is 50 feet below sea level, we represent this as -50. The negative sign indicates that the diver is below the reference point (sea level), and the absolute value of 50 represents the depth of 50 feet.
Therefore, the integer -50 correctly represents the situation of a diver being 50 feet below sea level.

if p q by the consecutive interior angles theorem which angles must be supplementary
Answer:
Angles 3 and 8 are consecutive interior angles
Step-by-step explanation:
Here, we want to use the consecutive interior angles theorem to find the supplementary angles
We start by looking at the transversal line
two angles that are directly above each other on the two lines are consecutive interior angles that are supplementary
We have this two as;
Since it is P and Q that are parallel, it is angles 3 and 8 that are consecutive interior angles
the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery. use the histogram to complete the table.
Answer:
45 and 50
Step-by-step explanation:
each large square is 5 minutes.
for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)
15 x 3 = 45
for 40 < t < 60 there is two columns of 25 minutes (5 x 5)
25 x 2 = 50
From the given histogram we have the values of the empty box are 45 and 50.
We have given that,
the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery.
We have to complete the given table.
What is the histogram?A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson.
each large square is 5 minutes.
for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)
15 x 3 = 45
for 40 < t < 60 there is two columns of 25 minutes (5 x 5)
25 x 2 = 50

Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?
9514 1404 393
Answer:
h = 2m
Step-by-step explanation:
We can put the given values into the area formula and solve for the missing one.
A = (1/2)(b1 +b2)h
7m²= (1/2)(3m +4m)h
7m² = (7/2)m·h
(7m²)(2/(7m)) = h = 2m
The missing height is 2 m.

A train travels 1 kilometre in 1 minute 20 seconds. Picture of steam train Question prompt At this rate, how many kilometres will the train travel in 1 hour?
Answer:
45km
Step-by-step explanation:
Distance covered in 1min 20sec (80sec) = 1km
Distance covered in 1 min (60sec) = 1km/80sec
Distance covered in 1Hr (3600sec) = (1/80)*3600 = 45km.
