Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Mathematics
1 answer:
Maru [420]3 years ago
6 0

Answer:

f(x)=8x^2+73x-70

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

f(x)=a(x-(-10))(x-\frac{7}{8})

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

f(x)=8(x-(-10))(x-\frac{7}{8})

now, we can simplify it

f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)

so, we get

f(x)=8x^2+73x-70

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.5 years with a
olga_2 [115]

Answer:

S.E = 0.108

Step-by-step explanation:

From the question we are told that:

Mean age \=x=5.5

standard deviation \sigma= 0.7 years.

Sample size n=43

Generally the equation for Standard error is mathematically given by

S.E= \sigma \bar x

S.E= \frac{\sigma}{\sqrt n}

S.E= \frac{0.7}{\sqrt 43}

S.E = 0.108

One leg of a right triangle is 3 cm and the hypotenuse is 5 cm. Joni found the length of the other leg by evaluating √32 + 52. W
vladimir2022 [97]

Answer: See explanation

Step-by-step explanation:

We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:

x² + 3² = 5²

x² + 9 = 25

x² = 25 - 9

x² = 16

x = ✓16

x = 4cm

The other leg is 4cm

Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.
