Answer:
Option C
Step-by-step explanation:
Given :-
A equation x² + 2x + 4 = 0 .And we need to find out the nature of the roots . The nature of the roots is determined by the Discriminant of the equation , and the Discriminant of a quadratic equation is ,
[tex]:\implies[/tex] Discriminant = b² - 4ac
[tex]:\implies[/tex] Discriminant = 2² - 4(1)(4)
[tex]:\implies[/tex] Discriminant = 4 -16
[tex]:\implies[/tex] Discriminant = (-12)
Now here the value of D is less than 0 .So the roots will be imaginary .
Hence the roots are imaginary and unequal.

Answer:
y = 3
Step-by-step explanation:
If the line needs to be parallel to the x axis, it must be Horizontal. The formula for lines like this is y= mx+c with m being the gradient. With a horizontal line, the gradient is 0 and therefore we get y=c.
To find c, we need to find the y intersect which is where the line passes through the y axis. Since it is horizontal and passes through the dot, we can find that c = 3 as the dot is at 3 on the vertical axis.
From this, we can see that the equation is y = 3.
Answer:
3
Step-by-step explanation:
the x-axis is horizontal and the numbers above and below it are 4 and 2 and the dot was right on the line so it was 3

The triangles are not similar.
What is similarity in triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
The Given triangle ZXB and DZN are not similar
Because,
XZ/DZ =XB/DN ≠ ZB /BN
XZ/DZ = 1/2
XB/DN = 1/2
ZB /BN = 1/3
Hence, the triangles are not similar.

If 25% of $2000 is spent on food,how much money is spent on food?
Answer:
$500
Step-by-step explanation:
Simply change the 25% into a decimal which is 0.25 and multiply $2000.
Or you can change 25% into a a fraction which is 25/100 and simplify giving 1/4. Then simply multiply $2000 by the fraction: 2000/1×1/4. Cross multiply which is 2000×1/1×4=2000/4. Now simply divide 2000 by 4 and you get 500 as your answer.

452.16 rounded to the nearest tenth
Answer: 452.2
Step by Step Explanation: Find the number in the tenth place 1 and look one place to the right for the rounding digit 6 round up if this number is greater than or equal to 5 and round down if it is less than 5
.
Rounding 452.16 to the nearest tenth gives us: 452.1.
Given that we need to round 452.16 to the nearest tenth,
We look at the digit in the hundredth place, which is the second decimal place, and round 452.16 to the nearest tenth.
One is the digit at the hundredth position.
We round down because 1 is less than 5, therefore.
Simply drop all the digits following the tenths place and leave the tenths place digit alone if you want to round down.
Rounding 452.16 to the nearest tenth, we obtain: 452.1.
Hence rounding 452.16 to the nearest tenth gives us: 452.1.

HELPPPPP plsssss i need this answer ASAP
Answer:
0.05 in decimal form or 1/20
Step-by-step explanation:
Since there are 20 blocks, we are going to divide 1 by 20.
Result: 00.5
To get it in fraction form we are going to multiply 1/4 by 1/5 and get 1/ 20 because 4 x 5 = 20. There is no way to simplify this.
Therefore, your answer would be 1/20.

f(x) = 3x + 10g(x) = 4x - 2(f - g)(x) = f(x) - g(x)
(f - g)(x) = (3x + 10) - (4x - 2)
(f - g)(x) = 3x + 10 - 4x + 2
(f - g)(x) = - x + 12
(f - g)(x) = - x + 12 is the right answer.How much force is needed to push a 10kg ball to an acceleration of 0.8 m/s2?
Answer:
Mass of the object (m)= 10kg
Acceleration of the object (a)= 2m/s^2
Force acting on the object (F)= ?
Solution
F = m × a
F = 10 × 2
F= 20N
The force acting on the object is 20N.
Step-by-step explanation:
8N of force is needed to push a 10kg ball to an acceleration of 0.8 m/s²
What is Force?Force is an influence that can change the motion of an object.
Given,
Mass of the object (m)= 10kg
Acceleration of the object (a)= 0.8m/s²
We need to find Force acting on the object (F)= ?
Force=Mass ×Acceleration
F = m × a
Plug in the values of mass and acceleration
F =10 × 0.8
F= 8N

work out the gradient of the line y=5x-3
Answer:
The answer is 5
Step-by-step explanation:
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer. The slope is 5.
The slope is the ratio of rise to run of a line. The gradient of the line y=5x-3 is 5
How to determine the gradient of a line?The gradient of a line is also known as the slope and it is the ratio of rise to run of a line
The standard equation of a line in slope-intercept form is expressed as y = mx +b
m is the slope or gradient
Given the equation of a line y = 5x - 3
