Answer:

As we see, the quadratic formula, which is a formula that is used to solve quadratic equations, can easily come up in real-life situations. ... A quadratic equation is an equation that can be put in the form ax2 + bx + c = 0, where the highest exponent is 2.Every parabola has an axis of symmetry which is the line that divides the graph into two perfect halves. Like the ellipse the parabola and its applications can be seen extensively in the world around us. The shape of car headlights, mirrors in reflecting telescopes and television and radio antennae are examples of the applications of parabolas.arabolas have different features too. If a material that reflects light is shaped like a parabola, the light rays parallel to its axis of symmetry will be reflected to its focus, irrespective of where the reflection occurs. Conversely, if the light comes from the focus, it will get reflected as a parallel beam that is parallel to the axis of symmetry. These principles work for light, sound, and other forms. This property is very useful in all the examples seen in the real world.

Can you conclude from the figure that ABC is similar to DEF? Explain.​
pishuonlain [190]

Answer:

Yes, we can conclude that Triangle ABC is similar to triangle DEF because the measures of the 3 angles of both triangles are congruent.

Step-by-step explanation:

We have the measure of 2 angles from both triangles, and we know that triangles have 180°, so we can solve for the measure of the third angle for both triangles.

Triangle ABC:

Measure of angle A= 60°

Measure of angle C= 40°

Measure of angle B = 180°- (measure of angle A + measure of angle C) = 180° - (60° + 40°) = 80°

Triangle DEF

Measure of angle E= 80°

Measure of angle F= 40°

Measure of angle D= 180° - (measure of angle E + measure of angle F) = 180° - (80° + 40°) = 60°

The measures of the angles in Triangle ABC are: 60°, 40°, and 80°.

The measures of the angles in Triangle DEF are: 60°, 40°, and 80°.

Since the measure of 3 angles of the two triangles are the same, we know that the two triangles are similar.

when you subtract one negative integer from another will your answer be greater than or less than integer you started with? Expl
pshichka [43]
Lets take   (-4) - (-6) 
             = -4 + 6     (here we changed the sign because in integers when you are                                                     subtracting <span>an integer, we put its opposite..thats the rule .)
            =. -4 + 6 = 2

so here we got the answer as 2 .....this shows that </span>your answer will be less than the integer you started with ....this is because here in subtraction we will first change the sign and then follow the same rules of addition ...so here if both the numbers have opposite signs then we subtract and put the greater number sign .....
<span>
Hope i am right !!!</span>
