1. The product of two consecutive integers is 20. Find the values of these integers.

1 answer:

4 0

First find the factors of 20
1 & 20
2 & 10
4 & 5
-1 & -20
-2 & -10
-4 & -5

Now find the pairs that have a difference of 1

-4 & -5
4 & 5

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?

Ghella [55]

Increased height:-

$\\ \sf\longmapsto 23\times 15\%$

$\\ \sf\longmapsto 23\times \dfrac{15}{100}$

$\\ \sf\longmapsto \dfrac{345}{100}$

$\\ \sf\longmapsto 3.45$

Now current height:-

$\\ \sf\longmapsto 23+3.45=26.45ft$

The x intercepts of the function f(x) = 2x(x-5)^2(x+4)^3 are…

Leokris [45]

Answer:

$\boxed{\sf x- intercepts = 0 , 5 \ and \ -4}$

Step-by-step explanation:

A function is given to us and we need to find the x Intercepts of the graph of the given function . The function is ,

$\sf \implies f(x) = 2x( x - 5 ) ^2(x+4)^3$

For finding the x intercept , equate the given function with 0, we have ;

$\sf \implies 2x ( x - 5 )^2(x+4)^3= 0$

Equate each factor with 0 ,

$\sf \implies 2x = 0$

Divide both sides by 2 ,

$\sf \implies\bf x = 0$

Again ,

$\sf \implies ( x - 5)^2=0$

Taking squareroot on both sides,

$\sf \implies x - 5 = 0$

Add 5 to both sides,

$\sf \implies \bf x = 5$

Similarly ,

$\sf \implies \bf x = -4$

Hence the x Intercepts are -4 , 0 and 5 .
